15kw Electric Furnace Breaker Size

However typically electric furnaces require a draw between 60 and 80 amps.

15kw electric furnace breaker size.

We use 220 instead of 240 just to be safe one does not always get 240volt on the circuit but it is the peak the above is true when there is zero loss. The input voltage will make a big difference in what size breaker you need to use. By multiplying the volts by amps you will receive total wattage. That is 15000watt 200volt x 68 2amp.

Element size heating output. Can i use 2 40 amp breakers with 6 wire instead of one 80 amp on a 4 wire. To protect against material failures the national electric code. 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. The size of a breaker is determined by the amp draw. Also just to be sure is it a 1 5k which is 1500 watts or 15kw which is 15 000 watts. 5kw 17 000 btu s 7kw 24 000 btu s 8kw 27 000 btu s 10kw 34 000 btu s 12kw 41 000 btu s 15kw 51 000 btu s.

I am replacing a propane furnace with a rheem air handler and 15kw heater kit. G g electric plumbing at 1900 ne 78th street ste. Each kw produces about 3400 btu s of heat so the heating output of the various heat strip options are as follows. The exact amps an electric furnace requires is solely based on the size of the furnace and its performance capabilities.
