jmp output transformer wiring color code

For single-phase, Black (for 120V) or Red (for 277) is used for Line and Grey is used for Neutral.Earth or protective conductor: Green/Yellow or Green or bare copper conductor.But most do share at least one thing in common: a way to identify each wire. Whether you install, repair or upgrade wires, you may have noticed, no two wiring systems are exactly the same. Neutral: White (for 120, 208, or 240 V), or Grey (for 277, or 480 V) But behind switch plates and outlets lies a colorful, spaghetti-like network of wires: red, black, yellow, green each designed to connect, and keep us safe.

The field coil finish is connected to pin 1 and the field coil start is connected to pin 4.

This system can be used where the field coil is used as a choke in the negative side of the power supply or where the coil is shunted to ground.

Phase – 3: Blue (for 120, 208, or 240 V), Yellow (for 277, or 480 V). Here the field coil and output transformer wiring are kept separate in the cable.

The color code adopted in the US is as follows: NEC does not instruct any requirements for other conductors. NEC mandates the color codes for neutral and protective ground as grey and yellow-green respectively.

National Electrical Code is followed in the United States and sometimes in Canada.
