![]() Watch out: as you see in the two illustrations at the left of our sketch, a circuit with a ground wire will present a bare or green-insulated wire and there will be three wires (or more) present. We discuss how electricians address un-grounded receptacles or circuits by other approaches such as replacing the receptacle with a Ground-Fault Circuit Interrupters (GFCI) type receptacle or "wall plug". National Electrical code such as NEC Article 250.130 Equipment Grounding Conductor Connections. We describe how to add a grounding conductor on older two-wire circuits that lacked an original grounding conductor, citing pertinent sections of the U.S. Here we discuss how to select & wire a two-wire ungrounded electrical receptacle when the electrical circuit has no grounding conductor. How to Hook up an Electrical Receptacle (wall outlet) on a Two-Wire Electrical Circuit We also provide an ARTICLE INDEX for this topic, or you can try the page top or bottom SEARCH BOX as a quick way to find information you need. Better to get help from a licensed, trained electrician. Watch out: if you are not trained in proper, code-legal, safe electrical wiring you should know that making a mistake can kill someone or set the building on fire. Electrical receptacles (also called electrical outlets or "plugs" or "sockets") are simple devices that are easy to install, but there are details to get right if you want to be safe. ![]() This article series describes how to choose, locate, and wire an electrical receptacle in a home. This article explains that when there is no safe grounding conductor or "ground wire" at an electrical receptacle location, you need to choose the proper receptacle type and make the proper wire connections for safety. ![]() How to wire an electrical receptacle ("outlet" or "wall plug") when there are just two wires (hot and neutral) but no ground wire.

Meets or exceeds all applicable ASTM specifications NM-B cables are LEAD FREE and RoHS compliant. It may be fished through masonry or tile walls, where not exposed or subject to excessive moisture or dampness. NM-B is rated at 600 volts and although it is rated at a conductor temperature of 90☌ dry, its ampacity is limited to 60☌ according to the NEC 2008 and NEC 2011. Its applications are outlined in NEC 2008 and NEC 2011 Article 334. ![]() ![]() Non-metallic sheathed NM-B cable is used in normally dry installations in residential wiring, as branch circuits for outlets, lighting and other residential loads. ![]()
