-trade size 27 (1")
-trade size 41 (1 ½")
-trade size 21 (¾")
-trade size 35 (1 ¼")

Answer 1

The size of conduit required for forty No. 14 RW90, non-jacketed, 600 V conductors is trade size 35 (1 ¼").

Step-by-step explanation:

The size of conduit required for forty No. 14 RW90, non-jacketed, 600 V conductors is trade size 35 (1 ¼").

The size of a conduit is determined by the number and size of the conductors that will be installed. In this case, there are forty No. 14 conductors, which have a diameter of approximately 1.628 mm. Based on industry standards, these conductors can be accommodated by a trade size 35 conduit, which has an inner diameter of 1.4 inches (35.6 mm).

It is important to match the size of the conduit to the size of the conductors to ensure proper installation and compliance with electrical codes.
