Installing wiring for a welder or air compressor is not as hard as you may think. Whether you are installing a new outlet or moving your existing 220 outlet to a new location this article will help you wire the outlet and breaker in the electric panel.
Current building codes require 220 outlet inslations to have a 4 wire cable, 2 hot wires, 1 neutral and a ground.
Dryers use a 10/3 wire and a 30 amp 220 volt breaker in the electrical panel. Check with the power requirements of your welder or air compressor to make sure that the wiring is sufficient for the power needed.
Dryers: When planning the new location of your dryer be sure to consider the length of the dryer vent and the length of dryer cords. Dryer vents can be up to 14 feet with 2 90 degree bends. If you need more bends then you must deduct 2' for each additional bend. The wiring for a dryer and the dryer outlet must be located close to your dryer location because the pig tails on most dryers are only 4' to 6' long.
