Just did a house today that had the laundry circuit tapped off the kitchen small appliance circuit. So when the GFCI in the kitchen was tripped all the electricity in the laundry, including the ceiling lights shut off. Another bit of information is the entire circuit was 14/2 AWG. Cool huh. That was just a couple of things I found. House was a POS.
