How do I know what size breaker I need?
Every circuit breaker has a specified amperage (amount of current). This rating is labeled on the breaker itself. The standard for most household circuits are rated either 15 amps or 20 amps. An important note to remember is that circuit breakers can only handle about 80% of their overall amperage.
What are different types of circuit breakers?
There are three basic circuit breaker varieties: standard breakers (which include both single-pole and double-pole circuit breakers), ground fault circuit interrupter circuit breakers (GFCIs) and arc fault circuit interrupter circuit breakers (AFCIs).
What does the issue number mean on a circuit breaker?
Thank you for the chanced to answer your question. Circuit breakers are marked according to UL with mandatory markings. The numbers you refer to are “issue” numbers which are allowed but not required by the UL (underwriters laboratories). Issue number is a manufacture number similar to catalogue or lot number.

Square D QO breakers are compatible with QO breaker boxes and CSEDs. Each ANSI-certified and UL-listed. Homeline circuit breakers are built with the same Square D brand quality you have come to expect at a price that makes them the best value in their class.
Can I use a GE breaker in a Siemens panel?
Siemens breakers can be used in GE breaker boxes, and they are generally known to be compatible. Match the size and voltage requirements when using Siemens breakers, as using the wrong breakers can have dangerous results. If the wrong breaker is used it could fail to break (shut off power) during a surge.
What breaker will interchange with Siemens?
The Siemens QP, QT, QAF, and QPF are the standard “interchangeable” plug-on type breakers used in loadcenters under several brand names including Siemens, Murray, Gould, and Sylvania to name the most common. It also fits most Midwest Power and Milbank Mfg metering equipment.
What is the difference between CH and BR breakers?
CH was originally Cutler Hammer (and now Eaton). BR has been rebranded a number of times, and was previously Westinghouse, Bryant, Cutler Hammer, and now Eaton. Me: I typically don’t install BR panels from scratch, everything is kind of cheap on quality.
