Does anyone know what FICA score marks are, like in practical am aware that you need 65% of the installation to be completed and working but I was wondering if anyone knew like what % the lighting circuit was, motor circuit etc
R1+r2, you can get a meter value for that by linking out the contractor and overload (so it closes the circuit) and test from there, using the r1+r2 you get you could then add that on to the ze of the board it is feed from? No? So for example say you're r1+r2 for the motor circuit is 0.85 and Ze...
So when you're doing what you're saying have you linked out the contactor and overload or just pushed the contactor in? To close the circuit? I was thinking, see how zs=ze+(r1+r2)
could you use the r1+r2 given by the meter and the ze from the meter reading
