Red white black and copper wire. Im confusedi thought white was always considered a neutral wire. The supply circuit has a black red white and copper wires. Youll have two cables in the switch box a live one with a black and white wire and the one going to the outlet which has a red black and white wire. They should both be of the same wire gauge. Join the black wires from both cables together add a 6 inch jumper cable of. The standard ground wire color is either bare copper or green.
I color coded them but i am left with the blue wire from the fan and the copper and red wire from the supply circuit. In the standard wire color code the hot wire in a cable with two conductors plus ground is black and the extra hot wire in a three conductor set is red. When a white wire is augmented with a red or black color marking this often indicates that it is being used as a hot wire rather than a neutral wire. White wires are always neutral in 110 volt circuits but can be used as the second hot wire or switch leg in 240 volt applications and three way switches respectively. The wires running to the element are black and white but the white wire is wrapped with red tape. 12 awg for 20 amp circuits and 14 awg for 10 and 15 amp circuits.
According to the instruction stated to connect the ground conductor of the 120v supply this may be a bare or a wire with green colored insulation to the green. Red wires are also hot wires.
