230 volt single phase wire colors. Single phase power equations single phase electrical power equations. Because a red colored wire also serves as an ungrounded conductor these wires are used to connect the second leg of the electrical system to loads which require 240 volts. These systems are common in home and office environments. For wires that will be 120 208 or 240 volts the following wiring color standards are used.

Two hot wires each 133v from ground and not one hot wire 230v from ground and a neutral wire. The red wire is also used as a by pass in a two way switched lighting circuit and will often be used also as an interconnection or communication wire in a circuit that requires it such as a smoke detector circuit. This ensures secure connections. If the wiring system has one phase at a higher voltage than the others using a high leg connection that phase s wires should be marked with orange.

It is important to note that with this type of wiring there are multiple phases in place each of which will get its own color wire to make it clear what it is for those working on it.
