I currently have a 200amp main panel that has no room for additional breakers. However I want to add circuits for the following: 1) 50amp circuit for a hottub 2) 50amp circuit for my garage for intermittent use of a welder and air compressor 3) 15-20amp circuit for general use
I plan to add a sub-panel this weekend. What I'm trying to determine, and I seem to get varying answers from the supply stores, is WHAT amperage do I need to supply the new sub-panel with? My initial thought was 100amps just to make sure I had the required power, but appropriately, it was pointed out that not all of these items would run at the same time, so a 60amp breaker may be sufficient to run the sub-panel.
I'd like to get some sound advice on which I should run, and what gauge of wire should be run between the two panels. My thought is to run a 4gauge regardless.
Any thoughts are sure appreciated.
