Sorry for the possibly dumb question, new to this sorta stuff!
If this were a house I'd be all set but I haven't seen a breaker that looks quite like this.
Our lower 20a breaker hums and clicks off a lot due to running a big electric heater off of the outlet most the winter which wore it out (being on the verge of popping off so long).
So, need a replacement now but not sure where to find one! Is it standard or is it some weird proprietary obsolete thing?
