[QUOTE="Tim McCulloch, post: 30721, member: 67"] Re: L5-30 wire for 220V? This is being fed from 2 phase legs of a 3 phase service. That's why you metered a nominal 208v. between the 2 hot legs. There is no neutral, or the neutral is being used illegally as the ground... or there is no neutral and the receptacle is wired correctly for a 220v load that does not require a neutral such as an electric range, clothes dryer or room air conditioner. For those types of appliances, Code permits the use of the ground as neutral for timers, internal control circuits and small lights that require 120v. In our contracts we specify either "100 amp, single phase (split phase), 4 wire service" or "100 amp 3 phase 5 wire service." "All electrical service shall have separate Neutral and Ground wires that are not bonded except at the point of service. If you are unsure please consult a licensed electrician and have him/her call us while on your premises." You should not use this outlet. Tim Mc [/QUOTE]
