Wiring 240 Volt Circuits How to Wire a 120/240-Volt Receptacle for an Electric Range The electrical circuit that powers an electric range must be of sufficient amperage to supply the necessary power to the range. The power demand of ranges varies depending on the rating of the appliance, but in most cases, a 50-amp 240-volt circuit is required, wired with #6-gauge wire. Understanding 220 or 240 volt Electrical Circuits That is why some 240 volt circuits have four wires: 1) A black wire which is often known as the "hot" wire, which carries the current in to the fixture. 2) Another "hot" wire which is red, which also carries current in to the fixture. 3) A white wire called the neutral which completes the electrical circuit for the 120 volt accessories only. Understanding 220 and 230 Volt Wiring | DoItYourself 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 as 110-volt circuits are now 120-volt circuits.
