Fill in the blank
The resistance of a wire is 126.48 ohms at 1000C and 100 ohms at 300C. The temperature coefficient of this wire at 00C is ____________ per C0.
determine the correct box size for each of the following conditions:1. Two nonmetallic sheathed cables with two 12 AWG conductors, a grounding conductor, and a switch in a metal box.
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.
