What size breaker do I need for an electric heater?

Multiply the value for current by 125 percent to determine the size of the breaker you need for the heater. A 1500-watt heater on a 120-volt circuit thus needs a breaker of 15.6 amps. Because a 15-amp breaker would be too small, you need a breaker with the next highest rating, which is 20 amps.

How do I stop my electric heater from tripping the breaker?

The first thing to do when a space heater trips the circuit breaker is to see if you are running the heater on the highest level. Most heaters have 2 settings for watts used. If your has that, reset the breaker and try to use it at the lower level. It might work fine on LOW heat (without tripping) but not on HIGH heat.

Does an electric heater need a dedicated circuit?

Space heaters usually consume upward of 1,000 watts, making them the kind of appliance that requires a dedicated circuit – not a general one. If your space heater is continually overloading a general-purpose circuit, you may want to switch it to a dedicated one.

Why does my heater trip the circuit breaker?

A furnace that starts up but immediately trips the breaker can be caused by an electrical short circuit or ground fault inside of the furnace itself. Both short circuits and ground faults greatly increase the amount of electrical current your furnace is pulling, which trips the breaker.

What size breaker do I need for a 5000W heater?

How to calculate water heater wire and breaker size

No.	Water heater element power (W)	Circuit breaker (A)
5	3,000	20
6	4,000	25
7	4,500	30
8	5,000	35

Will a bad element trip breaker?

Bad Heating Element As we’ve discussed, most electric water heaters have upper and lower heating elements. Sometimes, the casing on the heating element can split. This exposes the electrical portion of the element to the water in the tank, causing the element to short the circuit and trip the limit switch or breaker.

Does a 1500 watt heater need its own circuit?

Space heaters can range from 400 to 1500 watts, but a good rule of thumb is that the maximum watts per outlet should never exceed 1500 watts. In other words, yes, your 1500-watt heater needs its own circuit.

How many amps does a 1500 watt heater use?

12.5 Amps
According to google – A 1500 watt space heater (on high setting) will draw 12.5 Amps.

How do I reset my furnace breaker?
