- Two 12-2 AWG and two 14-2 AWG nonmetallic-sheathed cables enter a box. Each cable has an equipment grounding conductor. The 12 AWG conductors are connected to a receptacle. Two of the 14 AWG conductors are connected to a toggle switch. The other two 14 AWG conductors are spliced together because they serve as a switch loop. The box contains two cable clamps. Calculate the minimum cubic-inch volume required for the box.arrow_forwardQUESTION 12 What is the minimum sized IMC conduit we should use for the above wire run if it is 24 inches long? a 1/2" b 3/4" c 1" d 1 1/4"arrow_forward12.
