I am installing a tanning bed for my wife, and it requires and 80Amp breaker which says #4 wire. I am putting a 100 amp disconnect box beside bed ( because cannot find an 80amp disconnect box) and I want to know if the neutral wire needs to also be #4 in size or can it be smaller? The spot in box to connect the neutral wires looks to be smaller then the hot wire connection spots. Can anyone with knowledge on this help me out?
