Outlets & switches
Standard duplex outlet
The familiar wall receptacle with two plug-in positions. A grounded receptacle has two slots and a ground opening at each position.
Types, warning signs & next steps
What it does
Provides a connection for portable appliances and lamps. The face alone does not confirm wiring condition or available circuit capacity.
Know the differences
Standard, tamper-resistant, decorator-style and specialty receptacles can look similar. A three-slot replacement does not by itself add an equipment grounding conductor.
What you may notice
A plug that will not stay seated, a cracked face, discoloration, unusual heat or intermittent power deserves attention. Stop using a damaged receptacle; do not hold a loose plug in place.
What to tell Guardian
Tell us the room, what was connected and whether other outlets are affected. A photograph of the intact faceplate is enough; leave the cover on.

What to tell Guardian
Describe how many switch locations control the light and what changed. Do not remove the plate to identify wiring.
Further information: Consumer Product Safety Commission
Residential slide dimmer.
Outlets & switches
LED-compatible dimmer
Usually a slider, rotary knob or rocker with a small brightness adjustment. Some versions have an electronic indicator bar.
Types, warning signs & next steps
What it does
Adjusts brightness when the lamp or driver and dimmer are compatible. A lighting dimmer is not a universal motor-speed control.
Know the differences
Forward-phase, reverse-phase and other control methods serve different equipment. Compatibility, load range and multi-location arrangements matter.
What you may notice
Flicker only at low brightness, a delayed start or lights dropping out can point to compatibility or adjustment issues. New heat, odor or crackling needs professional attention.
What to tell Guardian
Send the lamp or fixture model and dimmer model if visible without opening equipment. Note whether flicker affects one lamp or several rooms.
Further information: Leviton dimming guidance
Radio-controlled dimmer and remote, rather than a Wi-Fi model.

Types, warning signs & next steps
What it does
Adds scheduling, occupancy response or remote control to compatible lighting or equipment.
Know the differences
Occupancy controls can turn lights on automatically; vacancy controls commonly require manual-on. Smart switches may depend on a hub, network and particular wiring.
What you may notice
Lost app control is different from loss of electrical power. Lights switching unexpectedly may involve schedules, sensor coverage or configuration as well as hardware.
What to tell Guardian
Tell us the desired behavior, device brand and any existing hub. Never assume a neutral conductor is present based on the faceplate.
Further information: Consumer Product Safety Commission
Breaker panel with its outer door open and protective front in place.
Panels & power
Electrical panel / load center
A metal cabinet containing rows of circuit breaker handles behind a protective front. The main disconnect may be here or elsewhere.
Types, warning signs & next steps
What it does
Distributes power into circuits. Its condition, listed equipment and supply arrangement matter as much as the number of empty spaces.
Know the differences
Main-breaker panels, main-lug panels and subpanels have different roles. A panel rating does not establish the complete service capacity.
What you may notice
Missing protective pieces, water marks, corrosion, unusual sounds or repeated circuit problems should be assessed. Do not remove the screwed-on protective front or touch suspect equipment.
What to tell Guardian
Share a safe photograph of the exterior and existing labels. Tell us what you want to add and any utility or inspection notice.
Further information: Eaton equipment guidance

Panels & power
Branch circuit breaker
A small labeled handle in the electrical panel, sometimes with a TEST button. Some circuits use a linked multi-pole breaker.
Types, warning signs & next steps
What it does
Protects its circuit against overcurrent. It is selected for the circuit and compatible panel, not simply by fitting into an opening.
Know the differences
Standard, AFCI, GFCI and dual-function breakers have different protective features. Brand, series, poles and ratings need to match the intended installation.
What you may notice
A breaker that repeatedly trips is a symptom to investigate. Installing a larger breaker or repeatedly resetting it is not a repair.
What to tell Guardian
Note which rooms or equipment lost power and what was running at the time. Read labels only from a safe position with protective covers in place.
Further information: Eaton equipment guidance
Guardian installation photo: main breaker exposed during professional work. Keep installed panel covers in place.
Panels & power
Main breaker
Often a larger breaker or linked handle marked MAIN in a panel or separate service enclosure. Location varies by property.
Types, warning signs & next steps
What it does
Provides overcurrent protection and a disconnecting means for the equipment it supplies. It may not shut down every energy source at a property.
Know the differences
A main breaker is different from the smaller branch breakers. A main-lug panel may rely on an upstream disconnect.
What you may notice
Widespread power loss, damage or unusual sounds at service equipment can involve more than one branch circuit. Stay clear of heat, arcing, water or damaged equipment.
What to tell Guardian
Tell us whether neighbors are affected and whether the home has solar, a generator or batteries. Do not open the enclosure or attempt service work.
Further information: Eaton equipment guidance

Cracked insulation, damaged sockets, missing plug parts, hot connections or rain-related trips are reasons to stop using the affected set. Do not bypass protective equipment.
What to tell Guardian
Read the set’s labeling for connected-string limits and intended location. Ask about a properly planned exterior outlet instead of relying on permanent extension-cord routing.
Further information: Consumer Product Safety Commission
Guardian ceiling-fan project.
Lighting & fans
Ceiling fan
Blades surround a motor mounted at the ceiling, sometimes with a light below. A short downrod, flush housing, pull chain or wall remote can help identify the style; none reveals whether the hidden support is suitable.
Types, warning signs & next steps
What it does
Moves room air for comfort. The light and motor may use separate controls, and a fan needs support designed for its weight and movement.
Know the differences
Flush-mount and downrod fans suit different clearances. Indoor, damp-rated and wet-rated models serve different locations. Remote, smart and wall controls must be compatible with the selected fan.
What you may notice
New wobbling, scraping, unusual noise, intermittent operation or a light that flickers deserve attention. A fan that hums but will not turn can have several causes. Stop using a visibly loose or damaged fan rather than trying different speeds to make it settle.
What to tell Guardian
Share the model, ceiling height, control type and whether the fan or only its light is affected. Photograph from the floor; do not remove the canopy or climb to inspect wiring.
Further information: U.S. Department of Energy
Bathroom exhaust grille; the motor and duct are concealed.
Lighting & fans
Bathroom exhaust fan
Usually a grille in the bathroom ceiling or wall, sometimes surrounding a light. Its motor connects to an exhaust route above or behind the finished surface; the visible grille does not show where the air goes.
Types, warning signs & next steps
What it does
Removes moist or stale room air through a suitable outdoor exhaust route. Electrical power, controls and the air path all affect the result.
Know the differences
Fan-only, fan/light and fan/heater combinations have different electrical demands. Humidity sensors and timers add control choices. Airflow, sound rating and duct compatibility matter alongside grille size.
What you may notice
Persistent moisture, rattling, slow starting or a running fan that moves little air may involve the fan, duct or outside termination. A new motor alone may not solve a blocked or unsuitable air path. Stop using equipment with burning odor or visible damage.
What to tell Guardian
Describe noise, room conditions and whether the light or fan works. Share the model if already available and mention attic access. Guardian can define electrical work and any separate duct or finish work.
Further information: Broan-NuTone guidance · Broan-NuTone guidance
Exterior cap of a powered attic ventilator.
Lighting & fans
Powered attic ventilator
A powered attic ventilator may sit behind a gable grille or under a roof-mounted cover. It is different from a whole-house fan that draws air from living rooms through a ceiling opening.
Types, warning signs & next steps
What it does
Moves air through the attic as part of a ventilation arrangement. Intake openings, controls and the building itself must be considered with the motor.
Know the differences
Roof and gable units use different mounting arrangements. Models may use electrical or solar power and temperature or humidity controls. They are not interchangeable with bathroom or whole-house fans.
What you may notice
New vibration, repeated starting and stopping or failure to run under its expected control conditions can signal a problem. A hot attic alone does not prove the fan has failed. Water staining near roof equipment also needs the roof and flashing assessed.
What to tell Guardian
Share any known model and control settings, when the behavior occurs and whether roof work was recent. Stay off the roof and avoid entering an unsafe attic to identify equipment.
Further information: Broan-NuTone guidance
Combination smoke and CO alarm; age and condition cannot be confirmed from a photo.
Safety & protection
Smoke and carbon monoxide alarms
Often round or rectangular ceiling or wall devices with a test button, openings and indicator lights. Read the visible label: a smoke alarm does not necessarily detect carbon monoxide, and a combination unit should identify both functions.
Types, warning signs & next steps
What it does
Warns occupants about the hazard the device is designed to detect. Smoke and carbon monoxide require different sensing functions, even when combined in one housing.
Know the differences
Smoke-only, CO-only and combination alarms may use batteries or building power with backup. Interconnection can make compatible alarms sound together. A commercial fire alarm system is a different arrangement.
What you may notice
Treat a smoke or CO alarm as an emergency: leave for fresh air and call 911 from outside. A periodic chirp can mean battery, fault or end-of-life information, but patterns vary by model. Never assume a sounding alarm is harmless because nothing is visible or smells unusual.
What to tell Guardian
After immediate danger is addressed, share the model, age if known and displayed message. Follow the manufacturer's maintenance guidance; do not disable alarms to stop the sound. Guardian can assess electrical supply and replacement compatibility.
Further information: Kidde alarm guidance · Kidde alarm guidance
Whole-home surge protective device shown for identification.
Safety & protection
Whole-home surge protective device
May be a labeled module at the electrical panel, a device mounted beside it or protection integrated into compatible equipment. Status lights can be visible, but a closed panel's appearance alone does not establish whether surge protection is installed.
Types, warning signs & next steps
What it does
Helps limit transient voltage surges reaching equipment. It does not replace circuit-breaker protection, correct every voltage problem or keep appliances powered during an outage.
Know the differences
Service or panel protection and point-of-use protection serve different positions in a system. A power strip is not automatically a surge protector. Product ratings and installation requirements matter.
What you may notice
A changed indicator, fault message or visible damage warrants checking the exact product instructions and arranging assessment. Indicator colors vary. Appliances failing after a storm do not by themselves prove that a surge protector failed or that the original problem was a surge.
What to tell Guardian
Send a safe exterior photo of the label and indicator plus the event timeline. Leave panel covers in place. Ask which equipment the proposed protection covers and what any manufacturer warranty actually includes.

An enclosed engine unit permanently located outdoors, typically connected to fuel and transfer equipment. Its cabinet differs from a wheeled portable generator. A wall display or app may show readiness, running status or a fault.
Types, warning signs & next steps
What it does
Produces electrical power when the arranged backup system calls for it. Capacity, selected loads, fuel supply and transfer equipment determine what the home can operate.
Know the differences
Permanent standby systems and portable generators require different arrangements. Whole-home and selected-circuit plans describe the intended loads; the generator's size and load-management design still need review.
What you may notice
Missed exercise cycles, fault messages, unexpected shutdowns or a running engine without expected house power need assessment. Generator exhaust contains carbon monoxide. If a CO alarm sounds, get everyone outside and call 911. Portable generators must never operate indoors or in a garage.
What to tell Guardian
Share the model, displayed fault, service history and which loads are affected. Do not open energized equipment or experiment with connections. Electrical transfer work and engine or fuel maintenance should be identified in the service scope.
Further information: www.generac.com · Consumer Product Safety Commission
Automatic transfer switch with enclosure open for the reference photo. Installed equipment should remain closed.

A labeled electrical enclosure near service or distribution equipment, sometimes with a visible operating handle or status display. It can resemble another panel. The label and installed system, not cabinet size, identify its role.
Types, warning signs & next steps
What it does
Selects the approved supply arrangement for backed-up circuits and separates sources as designed. It is a key part of safely connecting backup power to building wiring.
Know the differences
Automatic and manual transfer equipment serve different systems. Selected-circuit and service-level arrangements have different scopes. A suitable interlock arrangement is another design option, not an interchangeable switch accessory.
What you may notice
Backup equipment running without the expected circuits receiving power, an unusual transfer delay or a displayed fault deserves professional review. Those symptoms can involve controls, supply or the generator itself. Do not force a handle, bypass protection or feed a home through an ordinary receptacle.
What to tell Guardian
Provide exterior equipment labels, generator details and which circuits you expected to run. Keep covers closed. Guardian can review compatibility, load planning and the electrical transfer arrangement before recommending changes.
Further information: www.generac.com · support.generac.com

Backup & connected systems
Electric vehicle charging equipment
Usually a wall-mounted unit or cordset with a vehicle connector, cable and status indicator. Some plug into a receptacle; others are hardwired. The connector shape alone does not establish available charging power or circuit capacity.
Types, warning signs & next steps
What it does
Supplies controlled power to the vehicle for charging. The vehicle, equipment settings and electrical installation together determine the achievable charging rate.
Know the differences
Home AC Level 1 uses a compatible 120-volt arrangement; AC Level 2 generally uses 240 volts. Connector compatibility, hardwired versus plug-in installation and load management need to match the actual vehicle and property.
What you may notice
Interrupted charging, repeated protective-device trips, damaged cables, discoloration or unusual heat deserve assessment. Slow charging can also reflect vehicle settings, scheduling or equipment limits. Stop using visibly damaged equipment; do not substitute an extension cord or adapter to work around an unsuitable supply.
What to tell Guardian
Share the vehicle, charging-unit model, fault message and intended parking location. Note whether the issue affects one car or several. An empty panel space alone does not confirm capacity for a new charger.
Further information: afdc.energy.gov · afdc.energy.gov
Wall-mounted solar inverter; displays and connections vary by model.
Backup & connected systems
Solar inverter
May be a labeled wall-mounted enclosure near electrical equipment; other systems use smaller inverters at individual solar panels. Roof panels alone do not show which arrangement is present. Status may be displayed on the unit or monitoring app.
Types, warning signs & next steps
What it does
Converts solar-generated direct current into alternating current for the electrical system. Its controls and approved connection determine how the system interacts with the building and utility.
Know the differences
String inverters, panel-level microinverters and hybrid inverter systems use different designs. Solar production alone does not establish outage backup; backup requires the appropriate equipment and operating arrangement.
What you may notice
Fault messages, an unexpected extended production loss or damaged exterior equipment need investigation. Weather, shade and monitoring communication can affect reported output. A loss of app data is not proof the array has stopped producing. Keep away from damaged solar wiring and equipment.
What to tell Guardian
Share the inverter model, installer records, app message and when output changed. Stay off the roof and do not open disconnects or inverter cabinets for inspection. Guardian can establish the electrical scope and coordination required.

Types, warning signs & next steps
What it does
Delivers the electrical supply specified for the appliance. Circuit capacity, conductor arrangement, protection and connection method must suit the equipment and installation.
Know the differences
Dryers, ranges, ovens, dishwashers, water heaters and HVAC equipment can require different supplies. A replacement appliance may differ from the old one. Hardwired and cord-connected models are not universally interchangeable.
What you may notice
Repeated trips, intermittent heating, a discolored connection or power loss when equipment starts can involve the appliance or building wiring. Stop using a visibly damaged or overheating connection. Do not use a plug adapter or larger breaker to work around an incompatible installation.
What to tell Guardian
Share the exact appliance model, existing connection photo if accessible without moving heavy equipment, and whether the issue started after replacement. Guardian can assess the electrical supply; internal appliance repairs may require its service technician.
