I figured that, but just in case someone googled it and came in
halfway, I wanted that caveat to be there.
I've seen lots of recommendations here to use the next-size-bigger
wire just to avoid resistive losses, no surprises there.
And, it's possible to get 10 gauge wire that is *not* rated for 30
amps, depending on the insulation it's got. Remember, it's a fire
thing, not a capacity thing. Unlikely, but something to beware of.
