15kw electric furnace breaker size.
Each kw produces about 3400 btu s of heat so the heating output of the various heat strip options are as follows.
To protect against material failures the national electric code.
By multiplying the volts by amps you will receive total wattage.
I am replacing a propane furnace with a rheem air handler and 15kw heater kit.
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.
The electric furnace heating element options are displayed within the electric furnace pricing.
Element size heating output.
101 vancouver washington 98665 how to calculate breaker size wire size and wattages the chart below will help you determine fuse or breaker size and the necessary wire size to service various wattage loads.
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.
The manual says it needs a single circuit 80 amp breaker to split to 2 breakers in the unit with a jumper kit.
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.
However typically electric furnaces require a draw between 60 and 80 amps.
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.
