Finishing the basement and I need some more circuits. My load center is a square-d homc30uc. Best I've been able to tell is that this puppy will not accept tandem breakers. I figured no problem I'm put in a sub panel while it's all open. The sub panel I purchased does however accept tandem breakers. I was thinking about purchasing some of these for the sub panel just to leave a little bit of breathing room.
However on the instructions it indicated that my load center must be single phase. How can I determine this?
