It is more likely a 208v 230v or 240v motor.
Will a 240v heater run on 208v.
Putting it all together.
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.
Some motors are actually dual rated for both 50 and 60 hz with corresponding different speed and amp ratings.
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.
20a x 240v 4800 watts.
240v is the line to ground of a 415 240y system.
It will take longer to heat your water with less wattage.
Can you run a 240v clothes dryer on a 208v 3 phase connection.
220v is a line to ground voltage of a 380 220y system.
Therefore if you put 120v in you will get 120v out 208v in gets you 208v out 240v in gets you 240v out etc.
Say the tank draws 20 amps.
208v is a line to line voltage of a 208 120y system.
20a x 208v 4160 watts.
