Basic wire sizing guide for US 120 and 240 volts. Added by: snoofer . Useful info: # = American Wire Gauge (AWG), the lower the number the larger the wire guage. "Service cable" is large insulated stranded copper cable (usually refers to single #4 wire and up).

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. 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.

A 240-volt, 3-wire receptacle has three prongs (two hot and one ground) to accept a 3-prong plug. Plugs and receptacles for a 240/250-volt circuit can come in a number of configurations . Note : New electric ranges and clothes dryers require circuits that provide 120 volts and 240 volts at the receptacle.

Wiring residential homes with 240 volts is a necessity, for powering some heating and cooling equipment as well as some large appliances. The 220-volt circuits as they were known prior to the 1960s are now commonly known as 240-volt circuits and 110-volt circuits are now 120-volt circuits.

– The calculator allows entry of a voltage drop, but caution should be used when doing so to make sure you are calculating the wire sizes in accordance with NEC article 210-19 (FPN No. 4.) The NEC allows a maximum of a 3% voltage drop on the main branch of a circuit at the farthest outlet of power and 5% total to both feeders and branch circuits to the farthest outlet.
