Electrical Repair Questions? Ask an Electrician for Answers ASAP
A Master Electrician here to help. I am a double qualified; USA & UK electrician. Please give me a moment to formulate a reply.
10 Kw at 240 volts is 41.66 amps. 125% of this rating is 52 amps so the correct circuit breaker size is 60 amps and the disconnect will also be 60 amps. Wire size will depend on the length of run and the type of wire
Therefore please tell me the type of installation (residential commercial etc) and the approximate distance from panel to heater.
less than 60 ft. copper conductos
And will this be romex or conduit ?
Romex will need #6 copper
In fact in this case THHN in conduit would too.

A typo $12.
Thank you for using JA.
Any thing else?
what type of thermostat to use?
You will need a Line voltage thermostat but it may be very hard to locate one rated AT 60 AMPS. In this case it would be normal to use a thermostat controlling a contactor.
This would require some research by you at a supply soto
Home depot won't carry these contactors
thanks thats all.
