Assuming all terminals are rated 75°C and you have a #10 AWG THHN/THWN conductors in a conduit and the conduit is run on the roof off a office building where the ambient temperature never rises above 30°C the largest size circuit breaker or fuse permitted to protect these wires is:?
QUESTION 3 We are running 3 wires and a ground in a RMC to a control panel with a 60 amp circuit breaker disconnect in the control panel. The conduit is run along the ceiling where the ambient air temperature is 100 degrees. The control panel feeds our secondary cooling pump. What size are the ungrounded conductors? All conductors have typeTHHN insulation.
