Double pole right circuit breaker.

Can you run a 240v heater on 120v.

Contrast with a properly wired 240v circuit which can carry 3840 watts or almost 3x as much that is why baseboard heaters are mostly 240v. And your 120v wiring is correct as well you are indeed correct that the two water heater hots should be connected to hot and neutral of the 120v supply and the supply ground should ground the water heater. Single pole left vs. Prograde certified electrical contractor replied 2 years ago no a 50 amp circuit is not suitable for that use in that manner.

However your 240v wiring is a miss. Clothes dryers water heaters and and other high power 240 volt appliances cannot be run. Electrical circuit breakers should have amperage marked on the togle handle or on the top part of the module. So it wouldn t matter if you got a big baseboard heater that is 120v you couldn t hook it up anyway.

A 120 volt will normally have a single pole. Generally a 240 volt circuit breaker will have a double pole due to the large supply of energy that is needed to power the heater. As we know that the same water heater rated for 240v can be operated on 120v. Keep in mind that the same power rating water heater can be operate on both 120v or 240v ac.

You are indeed spot on that your heater will draw 9 375a when connected across a 120v supply. Keep in mind that you can t operate a 120v water heater on 240v ac. Can the breaker be changed to a 30 amp 240v and the outlet run the 2 1500 watt 30 amp 120v heaters. To get 240v from a 120v supply you use a 120 240v step up transformer.

There are no adaptors. Yes you can wire a 240 volt rated water heater with 120 volts exchanging the second hot red wire for a white neutral wire to the neutral bus.
