Outlet might not have neutral wire. Neutral not required for 240 volt Ground connexion: Look For green screw. More detail: If you take 3-prong outlet, but take four wires coming from breaker box, consisting of two Hots, a ground and a Neutral, then cap off the Neutral wire. Capping off Neutral wire creates no fire or shock hazard, as long equally twist on connector is very tight and covers all blank copper. |

Run into image of 12-3 wiring inside billow box  Pick: You can draw a Neutral wire from whatever nearby 120 volt outlet or ceiling box, and this Neutral connects to silver spiral on receptacle, however the 240 volt Hot wires must come up from a dedicated breaker that serves only that 240 volt receptacle.

 Larger paradigmChange 240 volt outlet into 120 volt outlet 1) Replace 240 volt outlet with 120 volt 2) In the breaker box, the 240 volt excursion has ii wires that connect to double breaker. 3) Get out Black wire continued to breaker. four) Remove other wire from breaker, and connect that wire to Neutral busbar. five) Ordinary 120 volt outlets take brass screws on 1 side for Blackness Hot wire, and silver screws on opposite side for Neutral wire. 6) caution: To alter 120 volt into 240 volt is not as easy unless the 120 volt is on a defended billow that serves just that outlet. Normally 120 volt outlets are connected several lights and other outlets. The 240 volt circuit needs to be dedicated, and then that but that 240 volt receptacle is served by that breaker.

 Example shows unusual case where 240Volt circuit has neutral and no basis wire. 240Volt circuit does non crave ground wire, or neutral. Both Neutral and ground wires join inside the breaker console, and are essentially serving same function. However, it is not code to complete 120Volt excursion using ground wire. So this instance lets each outlet have 120volt adequacy. Notice that X and Y are Hot, West is Neutral, and in that location is no G for footing. | |||

| iii-phase outlets and plugs Cooper phase wiring diagrams |
  Larger image Outlet shown can be used for 3-wire 3-phase or 2-wire unmarried-phase. iii-stage is commercial electricity used to achieve college boilerplate voltage and more efficiency. Voltages vary from 120-600 V depending on electric service and wiring is different than residential single-phase. Single phase requires two wires to consummate circuit: either Hot-Hot for 240 volt or Hot-neutral for 120 volt, while three-phase requires 3 Hot wires to complete each circuit: Hot-Hot-Hot. Single-phase is actually a derivative of 3-stage. Since 3-phase can have a Neutral wire along with the iii Hot wires, one Hot wire and one Neutral or two Hot wires make single-phase... so commercial applications can utilise 3-wire three-phase to run motors and process equipment while using ordinary two-wire single-phase for lights etc. Buy : Locking receptacles at Amazon Twist lock plug / 30 amp/ at Amazon Twist lock outlet / 30 amp/ at Amazon xxx amp generator outlet Resource: How to wire three-phase 3-phase electricity: from ability establish to stop user |
