phase wire

Each phase wire provides around 230 V to loads connected between it and the neutral.

The service drop consists of three phase wires and a neutral wire which is grounded.

With the 'delta' connection, this can cause variations in the voltages on the 3 phase wires.

Quadruplex is used where three phase wires are needed such as for 120/208 V high intensity lighting at stadiums.

The correct colour coding for the phase wire in a flexible mains lead is:

The three incoming phase wires connect to the busbars via a main switch in the centre of the panel.

However, "spur lines" branching off the main line to provide power to side streets often carry only one or two phase wires, plus the neutral.

Domestic properties are supplied with electricity by means of two wires, one termed the 'phase wire', the other the 'neutral'.

In this context, "polarity" refers to the order in which the neutral and phase wires are connected.

A "wye" ("star") transformer connects each winding from a phase wire to a common neutral point.

Each of the phase wires carries 50 Hz alternating current which is 120 out of phase with the other two.

In many countries outside North America, entire houses are typically wired from a single 240 volt single phase wire so this problem does not occur.

In this case the optical fiber is integrated into the core of a phase wire of overhead transmission lines (OPPC).

The phase wire is connected to one of the three phase wires forming part of the Electricity Board's main supply (3 phase and 1 neutral).

Transformers providing three-phase secondary power, which are used for residential service in the European system, have three primary windings and are attached to all three primary phase wires.

Phase wire in a circuit may be black, red, orange (high leg delta) insulated wire, sometimes other colors, but never green, gray, or white (whether these are solid colors or stripes).

The faulted, but energized, feeder can be found with a ring-type current transformer collecting all the phase wires of the circuit; only the circuit containing a fault to ground will show a net unbalanced current.

In balance condition the flux due to the current through the phase wire will be neutralized by the current through the neutral wire, since the current, which flows from the phase will be returned to the neutral.
