120V for @240V water heater
Comments (26)It sounds to me that the person asking the questions does not understand enough about wiring to do this safely and should get someone that knows what they are doing to help. Even if one does not get a shock or worst setting it up, there is always the fire hazard. Based on what I read so far, if he switches the elements to 3500's and they only run one at a time, then the 12/2 wire would be just fine and this is the way I have seen many a water heater installed. The thing I did not care for is the use of two single 20 amp breakers for a 240v load. Code requires the breakers to be tied together so that both trip if one trips. If he gets the correct breaker, this should be safe. Static...See MoreWiring 240V for pool pump and heater
Comments (14)As far as the GFCI is concerned there is nothing magic about the neutral. The fact that it is eventually connected to a ground has no effect on the operation. One of the basic laws of electricity is that current has to go somewhere. All the current flowing into a point has to flow out again. Kirchoff's current law. In a 110V circuit it flows in the hot and out the neutral or vice versa at any given time. In a 240V circuit without neutral it is the same, current flows in one wire must flow out the other. In the case of a 240V with neutral, the current flowing in on the wires must exit by one of the others. How it gets split up depends on the connected device. The whole point of a GFCI is that in a fault situation, the current doesn't use one of the wires, it instead flows through some other path. As I said, it's a basic law, current can't pile up anywhere, it has to go out if it comes in. It's just that it flows out via another bogus path (possibly through you). The GFCI is a simple device that measures the aggregate flow. If the in and out flow is the same it detects nothing and everything is fine... if more flows in than out or vice versa, it triggers the circuit that trips it. You could conceivably build a GFCI with any number of wires if you wanted. Now that being said, note that a GFCI doesn't save you from getting hurt in all situations. Get your self well insulated and then grab the two leads coming from the GFCI, and you'll get zapped. The GFCI sees no problem. The current comes in goes through you and then goes back out through the GFCI....See MoreChanging Over-Range GE Advantium 240V Interior Light Bulb
Comments (4)Thanks. The Advantium is at the top of a nice "breakfast station" installation with a pair of pocketing doors, above a toaster oven and coffee maker. It was put in by professionals, and I don't want to mess with it. I wish there was a stick-on battery-powered light that I could put inside the microwave. At least the Advantium uses one if it (easier-to-change!) halogen lights if you want to see the progress of whatever you've got cooking by pushing the button on the front panel....See MoreIs it possible to move a 240v outlet?
Comments (12)Hi there, if you are not too comfortable attempting this yourself, it is something an electrician can easily do, although it most likely will not be too cheap since it is going to involve a bit of effort. If I were moving a 240 outlet, I'd do the following: 1. As mentioned above, confirm the gauge of wire in the existing junction box is rated for the ampacity required of the new oven. I'd confirm the physical gauge itself and the breaker rating as well. You never know. Hopefully the wire in there now is type THHN, and the gauge is printed on the wire sheath. 2. Confirm wiring type. For 240v, you should have two hot wires, both black or one black and one red, a neutral (white), and you may or may not have a grounding wire (bare or green). Sometimes if steel conduit is used, it is also used as ground from a metal junction box. 3. Run wiring to new location. If you are moving the outlet to a completely new wall, I would cut the wire up in the attic, create a junction box up there, and then new wires down to the new wall. Assuming you have fire breaks in your walls, you won't just be able to fishtape down to where the outlet needs to be, meaning you or electrician will be knocking several holes in the drywall. If you are moving outlet a few feet along the same wall, I would do as mentioned above and use existing junction box to extend to the new location and put a blank plate over the old location when done making the connections. This will involve some drywall cutting as well. At the end of the day it's fairly straightforward, but a tad labor intensive considering it's just one outlet. Good luck!...See More12crumbles
