Electric hot water heaters typically require a dedicated 30-amp, 240-volt breaker. The wire supplying power from the breaker panel to your water heater will usually be a 10/2 Romex cable (Blk wire - hot , Marked White wire - hot , Bare copper wire - ground).
Beside above, what size wire do I need for a 4500 watt water heater? A 4500- watt element requires 10/2 wire and a 30 amp (220volt) breaker . The 3800 can be wired with 12/2 wire and a 20 amp breaker .
Consequently, what size wire do I need for a 50 gallon water heater?
The standard for water heater circuits is #10, two conductors with ground (10/2) and a 30 amp circuit breaker for a water heater . If you are running cable anyway, just run #10 and replace the breaker so it's done right, once and for all.
How many amps is a 50 gallon water heater?
Most 50 amp water heater will come with 4500 watt elements. On a 240 volt circuit that is 4500 / 240 = 18.75 amps , so, no, that will not trip a 20 amp breakers, however, it will be operating the breaker nearly 95% of its 20 ampacity rating and most breakers are not rated for that.
