I am building a dedicated music room. I had to get a new sub-panel placed, and want to set this up right the first time. So how does one make certain the breakers are in phase? Is there a test or trick to determine the phase orientation?
I have some very nice aftermarket audiophile fuse cartridges, but they are DIN and don’t fit my breaker bar. Is there a way I can use these with my breaker panel without having to do anything crazy?
