Standard single-pole and double-pole breakers
Standard circuit breakers provide overcurrent protection for overloads and short circuits. On a typical residential 120/240V supply, a single-pole breaker commonly serves a 120V circuit. A two-pole breaker is commonly used for 240V equipment, with the required arrangement determined by the circuit and equipment.
Pole count, amp rating and protective features describe different things. A two-pole breaker is not simply a way to double the usable capacity of an existing outlet. Wiring, equipment requirements and the panel’s approved arrangements must be considered together.

AFCI, GFCI and dual-function protection
An AFCI breaker adds detection of dangerous arcing associated with electrical fires. A GFCI breaker adds protection against ground-fault shock hazards. A dual-function breaker combines these two protective functions as well as its overcurrent protection.
“Combination AFCI” is a different term: it refers to protection against both series and parallel arcing, not automatically to GFCI protection. Guardian identifies the actual device and circuit rather than choosing a replacement by the color of a test button.

Compatibility is more than physical fit
A breaker must be suitable for the exact panel and application. Matching appearance, width or brand name alone is not enough. Manufacturer labeling and applicable listed or classified compatibility documentation govern the selection; some specifically classified replacements are approved for identified panels from other manufacturers.
Do not install a higher-rated breaker to stop repeated trips or replace a protective type with a standard breaker to avoid its warnings. The cause may be the load, wiring, connected equipment or the protective device itself. Diagnosis comes before a remedy.

What to send with your request
Describe the affected rooms or equipment, when the issue began and any recent changes. If safely accessible, a photo of the outside of the closed panel can help; leave protective covers in place. The estimate depends on diagnosis, compatible part availability, equipment condition and any circuit repairs required.

Questions about circuit breakers
Does a tripping breaker mean the breaker is bad?
Not necessarily. It may be responding correctly to a fault or excessive demand. Guardian reviews the symptoms and circuit before recommending replacement.
Can you install AFCI or GFCI protection in my existing panel?
That depends on the panel, circuit arrangement and available approved equipment. We review suitable options instead of assuming every protective breaker fits every panel.
Will a new breaker fix a damaged panel?
A breaker replacement and a panel repair or replacement are separate scopes. Damage at the equipment or connection may require wider work, which should be explained before proceeding.
