Will A 240v Heater Run On 208v

220v is a line to ground voltage of a 380 220y system.

Will a 240v heater run on 208v.

208v commercial electric water heaters previously purchased great for a variety of commercial installations these efficient units are built to last providing temperature controlled water where and when it s needed. Say the tank draws 20 amps. Can run 208v heater on 240v. Putting it all together.

Therefore if you put 120v in you will get 120v out 208v in gets you 208v out 240v in gets you 240v out etc. It will take longer to heat your water with less wattage. 240v is the line to ground of a 415 240y system. 20a x 208v 4160 watts.

208v is a line to line voltage of a 208 120y system. When you run 120 208v single phase power into an isolation transformer the two individual hot conductors of 120v are combined into one 208v waveform. Can you run a 240v clothes dryer on a 208v 3 phase connection. For example 120 240 and 120 208 both provide 120v on standard receptacles but when using a dryer or hot water heater for example that appliance would be using 240v or 208v respectively.

The important dfference othere than maybe having too high or low a voltage is that one of the input leads is either ground referenced or both are hot.
