Circuit breaker differences


Need to add a few breakers to my panel for new circuits for bath remodel. I am likely going to hire this part out, but just out of curiosity, are all breakers the same? Meaning that home improvement stores carry multiple brands and even multiple models of the same rating breakers. I am sure when you shop for a light switch you can go by look and feel and color, but how does one shop for breakers?

In most cases the breaker you buy needs to be from the Mfg of the panel

There is the Square D reg 20a breaker
Then a 20a Square D Homeline breaker - less expensive model
Breaker must match the Mfg & in Square D's case the model line of panel

If you read the label in the panel it will tell what types of breakers can be installed.

Like SD said the brands and types must match.
