Infratech says it's UL approved. And it will be inspected, however they don't always look at every detail and just expect me to install correctly.
I just want to make sure it's safe and each individual heater wire has over current protection. Technically each 4KW heater wire is not a separate circuit.
45A or 50A breaker & #8 wiring feeds it then it's #10 to each heater on the contactor. Maybe the contactor has integral thermal protection up to 6KW, but that still doesn't necessarily protect the #10 for overload, unless part of the UL approval determined that each heater will never exceed it's KW rating.
