I guess I know the answer to these questions; I just want some reassurance
that it is reasonable.
I am removing three circuits from my workshop and putting in a subpanel; the
three are not adequate, and while I wish I had put a subpanel in much
earlier, it is better later than never. I will end up with 2 240v circuits
and 2 120v circuits.
1) My present 240v machines draw less then 10a, but I plan on replacing
themeventually with ones that draw 18-20a, so I will use #10 and 30a
breakers. Is it okay to use 30a outlets and put 30a plugs on my current
2) I don't think I will ever use more than 20a on the two 240v machines and
maybe 3a on the 120v at the same time, so a 50a breaker and #6 SER aluminum
is adequate. Does that seem right? The run to the breaker box is 80'; any
advantage to using #4 SER? It is not all that much more expensive, but I
expect it is much more difficult to work with.
