Yes. Stoves and dryers are the only special case where you could do this. It's been against US code for a couple of years now, so you can't do new installations that way anymore. [It's been against Canadian code for at least 30 years.] I wouldn't dream of doing it with a pool pump outdoors. You're compromising the ground. That plus water that you immerse yourself in doesn't mix. If you lost a ground connection (many ground connections really aren't that good - I've seen too many people just wrap them without wire nuts - or worse, assume that simply lying against the electrical box sides was sufficient), the pump frame, the fixture, and everything else bonded to them in the area could go hot. And you're just asking for corrosion - which'll kill the ground eventually if it's carrying any current. Bad. Really really bad. This is one of those "it'd probably work for a while" _will_ eventually bite you. now if he has a four wire (red, black, white, bare) line, then he can. Either he has four wire, or he converts the pump to 120V. Either way is reasonable. Might not be able to convert the pump to 120V, or the circuit may not be beefy enough for it. Strictly speaking, probably both approaches are still against code (code doesn't like sharing motors (except very small ones) with anything else on a circuit). But an inspector would probably let you get away with it for a light bulb or two on a "change" (rather than new install). A 240V bulb is by far the simplest/cheapest solution. -- Chris Lewis, Age and Treachery will Triumph over Youth and Skill It's not just anyone who gets a Starship Cruiser class named after them. |

Perhaps you should reread it: "Is this as simple as taking the 220 wires, and connecting only one hot wire side with the common wire and ground wire to a standard 110 volt outlet?" One hot wire...common wire...ground wire. What do you suppose he means by "common wire" other than neutral? I suppose that by that, he means the neutral wire which he *imagines* to be present in the existing 240V motor circuit -- but is almost certainly absent. He's certainly NOT referring to the ground wire since he says "common wire AND ground wire"...clearly two different wires. And of course he doesn't mean the other hot since he expressly stated "connecting only one hot wire" let alone that it would not make any electrical sense. I agree that it's clear he knows the difference between the two. What's not at all clear is whether he -- or you -- realizes that 240V circuits typically do *not* contain a neutral conductor. We won't know unless and until he clarifies but presence of a neutral is VERY STRONGLY suggested in the OP. Sorry, but that's just not correct. The description of the circuit as powering an existing 240V motor "VERY STRONGLY" suggests the ABSENCE of a neutral conductor. There is really nothing else "common wire" can mean. There is no need for this blather about using ground as neutral. He never said anything of the sort. Neither did I. But there is no evidence whatsoever, absent an actual count of the uninsulated conductors present in the cable or conduit, that the OP does in fact have a neutral available. Better still, count the insulated ones. There's probably only one that's uninsulated. Many people do not understand that 240V devices do not have or use a neutral conductor. The OP may be one of them. You appear to be another. -- The e-mail address in our reply-to line is reversed in an attempt to minimize spam. Our true address is of the form . |

With all 4 wires accounted for, just what do you (Doug) think the OP is referring to by "common" and "ground" ? Guess what: Some professional electricians will run a neutral in a 240v circuit even if the application doesn't require the neutral. They do it because it's a good practice that can save a lot of aggravation down the line. Admit it Doug. You read it wrong. It's as simple as that.

Look at it this way: if he *did* understand how 240V circuits are wired, he'd know what to look for and he'd know what to do with it, and would not have asked the question in the first place. In a 240V motor circuit, it's *very* unlikely that there is a neutral conductor present. The OP never said that he actually checked. He's assuming that there is a neutral.

He has not said if he's looked but he hasn't said that he hasn't either.
You are making an assumption based on the utterly ridiculous contention that if he did look and saw four wires he wouldn't be bothering to ask. Why is that utterly ridiculous? Because a non professional might still ask to make sure that it's OK in terms of safety and code since as we all know there are many things that might physically work that are not. Is it ok to put a 120V receptacle on one side of a 240V line? Will it work...of course. Is it safe and to code? That's the real question here and you went off on a tangent. Since the man asked if it's ok to hook up based on the presence of a neutral the logical response would be to treat it as though there is one. Naturally if there isn't then he cannot do it that way. Everyone else is treating the case based on the facts presented by the OP, whether those facts are verified truth or just assumed. If you want to add a little kicker along the lines of "hey there's a good likelyhood there is no neutral present and in that case here's what to do" then fine. But you're insisting that the poster's question is wrong on the face of it. Everyone else is answering the question as given. Is this a game you play? If a someone asks a question--any question--then obviously they must not be capable of doing the task they ask about. Trying to turn this place into alt.hvac? |

If you want to add a little Actually if you read the original post, the OP could have a neutral with only two current carrying conductors if he converts the circuit to 110V, which is what he is asking. To answer that question with any certainty you would need to know the HP of the motor, and maybe the distance from the pump to the panel. |

No, I don't think that's what he's asking although I agree there is at least a touch of ambiguity. While he does use the word "convert" in the first sentence when he says what he is proposing in the second sentence he refers only to things at the outlet end, nothing about at all about converting entirely to a 120V circuit. If he's proposing anything at the breaker end it's not contained in what he stated. Until he says otherwise I will presume he means to put a 120 outlet across one leg of the "220" (240) and neutral with a ground. Whether the neutral is there or not remains to be seen but that's the proposal that I get out of the posting. |

For all that have responded to my question, thank you. 74 reply's and
all offering excellent, intelligent, and clearly safety concise advice. As pointed out, the 240 volt - 3 wire (no common, just ground) is what I have. Common I would assume, is the alternating current line of one of the hots when not sending current, thus switching back and forth. This I do remember from my basic EE courses. My dilemma, the 240 volt pump circuit is approximately 200 feet from the electrical panel buried beneath a cement slab, thus pulling a new 120 volt line was not an option. Therefore, the suggestion of either using 240 volt lights, a 240 volt to 120 volt transformer, or which no one suggested, SOLAR lighting may be my only options. If I choose one of the first two, I will take everyone's suggestion and hire a licensed electrician! I must say, usenet groups are very helpful in understanding options and again I thank you all for first, qualifying that safety is the most important criteria, and cost the second. Regards |
220 volt to 110 volt

For all that have responded to my question, thank you. 74 reply's and all Most. :-) offering excellent, intelligent, and clearly safety concise advice. As pointed out, the 240 volt - 3 wire (no common, just ground) is what I have. Caesar Romano, I'll be waiting for your apology any time you're ready. It's just as I said: I didn't misread anything. You did. Common I would assume, is the alternating current line of one of the hots when not sending current, thus switching back and forth. That is not correct. The two wires have a potential of 240V between them, and EACH has a potential of 120V to ground. Neither one is "common". This I do remember from my basic EE courses. *Electronics* engineering, I presume, not electrical -- or else you don't remember as much as you think you do. :-) My dilemma, the 240 volt pump circuit is approximately 200 feet from the electrical panel buried beneath a cement slab, thus pulling a new 120 volt line was not an option.

If that's possible, that would solve your problem easily.
