yojoe79 said:Hi I am preparing for MY Red Seal Exam and I need some help with the conductor sizing for voltage drop. here is my question What is the minimum size RW90XLPE conductor for a load drawing from a 20amp Double pole breaker (120/240) if the distance is 94m?
As Aegis noted, 28-104 is for motor supply conductors, which is the last section of wire to the motor. But where possible, the wire running to that last junction point (which is connected to the motor supply conductors) if 90C wire, can be taken from the 90C column.Thanks. Also if you are sizing conductors for motors I was told that you always have to use the 75 degree column unless its a class A motor
