240v GFCI work with no neutral ?? Mike Holt's Forum Re: 240v GFCI work with no neutral ?? Sun Dance Instruction ManualCheck out the instruction manual for this spa.In the wiring diagram it shows a load neutral connection on the breaker not used.Thanks for your info.I am going to do some more reshearch.I have not had a chance to read your article yet. Paul Understanding 120 240V Wiring Color Code | DoItYourself No wire with any of those colors can be used for establishing a ground or neutral connection. 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. 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. 4 Smart Switches That Work With No Neutral Wire Looking at the diagram above, you should be able to see there are three ways to create a circuit: Connect A to neutral = 120V; Connect B to neutral = 120V; Connect A to B = 240V; Most wiring in your home is either 1 or 2 (120V). Certain applications that require a lot of power, such as a stove, are usually wired for 240V (3). Why no neutral with 220V wiring? Google Groups On a 240v circuit you only need a neutral if there are 120v loads. If it is a "pure" 240v load there would be no purpose for the neutral but you still need the Equipment Grounding Conductor for safety reasons. There was an aberration in the National Electric Code since the copper Can you wire 240V GFCI without a neutral wire? Answers On a 240 volt circuit both line wires are hot, so they may both be black, depending on the wire used. There is normally no neutral required unless you are also tapping off 120 volts between hot ... 2 hots no ground...explain this. | All About Circuits While doing some renovations on a house with a friend I realized I had bought a 240 volt baseboard heater for a small room. I said I'd go exchange it rather than have to re wire. Old house with only hot and neutral wire. He then said it was possible to run 240 with just 2 hot wires. Home Electrical Wiring Diagram and Installation Basics Most residential and light commercial homes in U.S. have a single phase 3 wire 120V 240V service. It consists of two inverted relative to each other lines and a grounded neutral. Connecting an electric load between any line and the neutral yields 120 volts AC. Connecting between both lines yields 240 volts AC (see the diagram). Wiring Diagrams for Electrical Receptacle Outlets Do it ... Wiring a 20 Amp 240 Volt Appliance Receptacle. This outlet is commonly used for a heavy load such as a large air conditioner. The outlet should be wired to a dedicated 20 amp 240 volt circuit breaker in the service panel using 12|2 awg cable.. With this wiring, both the black and white wires are used to carry 120 volts each and the white wire is wrapped with electrical tape to label it hot. Electric Work: How to wire 240 volt outlets and plugs How to wire 240 volt outlets and plugs 30 50 amp 3 prong Range: 10 AWG for 30 amp. ... Ignore Neutral screw if no neutral wire available MORE ILLUSTRATIONS BELOW ... the hot wires connect to side of outlet. Brass screw => Hot wire. 240 volt electric circuit has 2 hot wires. Green screw => bare copper or green ground wire Silver screw => Neutral.
