# Readers ask: What Size Circuit Breaker Do You Need For A 15 Kw Heating Element?

## How many amps does a 15000 watt heater use?

So 15,000/240 = 62.5 amps. Keep in mind if you are calculating the size of a wire to service power to the heater, the maximum current allowed is 80% of the rating for the wire. That means 62.5/.

## How many amps does a 10 kW heater use?

10kw thermal bands are often 9.6 kw. Fixed space heating equipment are assumed to have a continuous charge, so without any other charge considered, there are 9,6240 x 1,25 or 50 amps.

## What size breaker do I need for a 42 amp heater?

Your heater draws 10,000W / 240V= 41.67A, Since it will be on for more than 3 hours at a time, it is a continuous load, and the circuit supplying it must be sized at no less than 125% of the load. 41.67A X 1.25 = 52.08A. You need a 60A circuit protected by a 60A 2-pole breaker.

## What size breaker do I need for 3000 watts?

The 3000 watt is powered by a 14/2 cable and 15 Amp double pole breaker.

## How many amps is a 3 phase?

For example, a three phase circuit using 25,000 watts of power and a line voltage of 250 will have a current flow of 25,000/(250 x 1.73), which is equal to 57.80 amperes.
