Rodney Chant Apr 1, 20201 min readCable Temperature Rise part 2.You can see that the cable at 20 amps 2cicuits will rise about 30 degrees above ambient. So if the roof space was already 40 degree, or 50 degrees and you have HWS circuit and Air Cond circuit tgether??

Voltage Drop.To find the voltage drop on a circuit , you need to know the cable size , the cable length and load current. Using the formula Vd = ...
I leant that you can not put two circuits in an insulation especially when all the circuits draws more current like HWT and Air con .
