Will This Fit In Square D Homeline ?

Will This Fit In Square D Homeline ?
Asked by: Joe
Hi Joe, It is not recommended that you "Mix and Match" circuit breakers by using one brand in another manufacturers panel. Using a Siemens type QP circuit breaker would not be listed as approved in a Square D Homeline panel. If your panel were to be inspected it would not pass.

Do I need two of these to connect a range?

My box has two rows, will this connect across both sides in the circuit breaker?
Asked by: Lotek
Would have to see your service panel (box). These are typically stacked one atop one another, and the bus bar will have alternating stabs for each phase of the service (see picture). So, yes, this will be the breaker you would need to connect a 240V range rated at around 32A, but only if you have the same type of bus bar in your service panel.
