Yes, and while we're on dangerous., the neutral (white) wire should never be bonded to ground at the sub-panel, only at the main panel.
Adding second "dedicated" breaker box.
I am getting ready to hook up 3 20amp dedicated lines for my system and am wondering if installing a second breaker box directly off of the main line would be worth the effort. I thought this would be a better set-up than running them off the main box or a sub-panel. Thanks for the replies in advance.
