However typically electric furnaces require a draw between 60 and 80 amps.
15kw electric furnace breaker size.
The manual says it needs a single circuit 80 amp breaker to split to 2 breakers in the unit with a jumper kit.
I am replacing a propane furnace with a rheem air handler and 15kw heater kit.
Element size heating output.
That is 15000watt 200volt x 68 2amp.
The size of a breaker is determined by the amp draw.
Can i use 2 40 amp breakers with 6 wire instead of one 80 amp on a 4 wire.
Also just to be sure is it a 1 5k which is 1500 watts or 15kw which is 15 000 watts.
To protect against material failures the national electric code.
The electric furnace heating element options are displayed within the electric furnace pricing.
Each kw produces about 3400 btu s of heat so the heating output of the various heat strip options are as follows.
G g electric plumbing at 1900 ne 78th street ste.
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.
A 1500 watt heater on a 120 volt circuit thus needs a breaker of 15 6 amps.
Multiply the value for current by 125 percent to determine the size of the breaker you need for the heater.
The input voltage will make a big difference in what size breaker you need to use.
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.
