Common questions
Can I put a Siemens breaker in any panel?
No. Breakers must match the panel's listing — Siemens Q breakers are for Siemens/EQ panels or panels explicitly listed for them. Confirm compatibility with a licensed electrician and the CEC before installing.
What's the difference between GFCI and AFCI breakers?
GFCI breakers protect people from ground-fault shock; AFCI breakers detect arc faults that can start fires. Many Canadian circuits now require one or both — a licensed electrician can confirm per the CEC.
How do I know what amperage breaker I need?
The breaker must match the circuit's wire gauge and load — for example, 15A on 14-gauge copper. Never upsize a breaker to stop nuisance tripping; have a licensed electrician assess per the CEC.
