How big of circuit breaker do I need for 1500 watt water heater?
In a US household, the current draw for a 1500 watt water heater is 12.5 amps. Now, in order to choose an electric breaker, multiply the current draw of the water heater with 125 per cent in order to determine the size of the breaker you will need. In the above example, we would require a 15.6 amp circuit breaker for our US readers.
When to replace a circuit breaker on a water heater?
If after replacing the circuit breaker it is found that the water heater trips the breaker then the circuit wiring and breaker should be increased and replaced, as long as the water heater is working properly and without fault.
What kind of breaker do I need for a mobile water heater?
My electrical wiring project involves Change the Wiring a Water Heater in the Bathroom of a Mobile Home. An acquaintance has an older mobile (galvanized branch water lines), and his water heater: 40-gal/240v/dual 4500w (18.75A), connected to the circuit breaker panel Double Pole-40A breaker with a #12/20Amp cable.
How can you tell the size of a breaker for a water heater?
In order to determine the size of the electric breaker, we have to first know the current rating of the water heater. This can be found with the help of the power output of the heater and the working voltage which are present on the heater’s specification tag.
