I have a Winchester electric Furnace with 20 KW heat kit. I need info on what wire to use from the main breaker panel and what size breaker to install for it. here is the info from the website:
Requires dedicated double-pole circuit breakers, the appropriate gauge 240V wiring with proper polarity and ground. Register online for a 10 year limited parts warranty, including the heating element.
Direct drive, multiple-speed blower motor is permanently lubricated for maintenance-free operation and the speed is adjustable to match the air flow requirement of the installation application
Designed for use with both air conditioning and heat pump systems just match the width of the air handler cabinet to the width of the appropriate air conditioning or heat pump coil
20 kW heat strip with 60 and 50 amp double-pole circuit breakers
5 year limited parts warranty - 10 year limited parts warranty with online registration
MFG Model # : WMA48-20
MFG Part # : WMA48-20
The supply circuit needs to be sized to 125% of the load. 20 kW is 83.3 amperes at 240 volts. 125% would be 104.7 amperes. That would require no less than #2 copper conductors IF the terminals at the furnace are rated to 75 degrees C. More likely as not the furnace is designed to use two branch circuits of 52 amperes each which would require no less than #6 copper conductors with 55 or 60 ampere circuit breakers.
If the above is geek to you then you need to do some more studying of electrical systems.
The manual for that unit.
