I am new to this group but may be using it a lot since I have just bought a
house that is turning out to be a true Handy Man Special. Question: Some of my receptacles will run low voltage such as lights, but not very bright. A hundred watt bulb will only look like it is 50W. A vacuum cleaner will not even work. I have replaced all receptacles in the bedroom but there may be more switches and receptacles on this circuit. Can anyone tell what the problem may be and is there an easy way to test it? |

Try tightening all the wires in the panel below the main breaker. You really should turn off the main when you do this. Then turn on the main and see what voltages you are getting there. If your in the US it should be 240 phase to phase at the main and 120 from each phase to the ground/neutral bar/can. You need a vom, a Volt Ohm Meter to do this. If these voltages are not present then you need to call an electrician. Now check the outlets with your meter, if your not reading 120 volts ac then you still need an electrician. |

You just bought a house , did you have the electrical inspected. You
realy need a pro you may have serious problems |

I am not that familiar with the electrical Circuit box. When I bought the
house I had a home inspector look at it and he told me it has been recently upgraded. If the work has been recently done then I should be able to assume all the wires are tight. I can replace receptacles and switches but opening the Circuit box is out of the question. "SQLit" wrote in message news:yIk3c.15915$BA.11539@fed1read03... "CooSer" wrote in message ...

Do you live in Raleigh, NC. In my last house I had a problem (don't
remember exactly what it was) and asked the utility to check the line. They did and ended up digging up an outside splice. They said there was a bunch of defective splices used about 12 to 15 years ago. "CooSer" wrote in message ...

This house is in NY. Other circuits are working fine so I don't think it is
an outside splice. This was built in 1960 and by the way the wires are run, I think they had a shortage of electricians! "Art" wrote in message link.net... Do you live in Raleigh, NC.

Any chance you have aluminum wires? Second guess (also may be part of my first guess) you may have a floating ground. Do any lights brighten or burn out more often than expected? -- Joseph E.

You need a cheap voltmeter and one of those plug in polarity testers. You
can get both for under $25 at home depot. With the cheap voltmeter set to "AC voltage", stick one lead into each of the slots on your outlet (not the round-looking ground slot). Look at the meter...if it reads 110-120, you have the correct voltage....anything lower and you need an electrician to open the breaker panel and check things out professionally.

It sounds like you have a loose wire somewhere. If you have cheap receptacles with push-in wires, change them to the screw down type. Measuring the voltage with no load on the circuit is almost meaningless unless its no where near 120V. A poor connection will still show 120V when no load is present. If you're losing enough power that a 100W lamp dims significantly, you can probably find the problem with your hand -- the loose connection is going to get warm quick so feel each receptacle in the circuit chain. Also, a loose wire at a receptacle will affect the downstream receptacles too unless the receptacle is pigtailed to the wires. Consider buying a pack of black, white, and green pigtails at Home Depot with the wire nut on one end and fork terminal on the other. At the problem receptacles (or the one upstream from it), remove the wires from the receptacle, buy new receptacles with screws on the sides, and power them via the pigtails. Note - watch for receptacles with red and black wires -- these are wired different and you don't want to pigtail those together. Perhaps just re-terminate them under screws if you encounter these. If you know the path of the cable from outlet to outlet, you can plug a 100W lamp in at the last one and measure the voltage at each receptacle. Poorly terminated ones, or ones downstream of the bad one(s), won't have 120V across their prongs. Each time the voltage rop considerably, you've hit another high resistance connection. Also, realize that many houses in the 60's were wired so that power went to ceiling boxes first and then to receptacles. Ceiling boxes are larger and wires may fan out like an octopus at the ceiling. A bad connection here will also cause power loss to the down stream devices, so check the ceiling light connections too (especially since home owners tend to change light fixtures and many do it poorly). -- Mark Kent, WA |

These are really great ideas to try out. I am not any where near an
electrician but some of these ideas seem easy enough. My wires are copper not aluminum. I don't really understand what pigtailing does, but I am thinking about finding all of the receptacles and switches on the circuit and replacing them with new ones. Before I do this though I will by a voltage tester to see if that can pin point what receptacle/switch is bad. Last night I found that my converted basement has track lighting and after replacing a switch, found out that they don't light to capacity either. If I can't figure this one out I may have to bite the big one and call a pro. "Mark or Sue" wrote in message news:T7y3c.224776$uV3.949729@attbi_s51... "CooSer" wrote in message ...

To my knowledge, there are no appliances or lights running faster or
brighter. Question: I started replacing some receptacles already and I noticed the wires were switched like the following. Two cables running into the receptacle both have a black and white. Previous owner had a white from the left wire and a black from the right wire running to the same 'bottom' plug. Same at the top. I started running the wires with both black and white from the left screwed into the bottom plug, and both black and white on the right screwed into the top plug. Is this right? PS. My low voltage problem existed before I changed any receptacles. "HA HA Budys Here" wrote in message ... From: "CooSer" These are really great ideas to try out.

If I can't figure this one out I may have to bite the big one and call a pro. This bad circuit might be 1 of 2 bad circuits, the basement track being the other one? It's possible they're both fed from the same 3-wire, 2 circuit cable and the neutral has become disconnected where the 3-wire cable splits into 2 circuits. A loose or broken neutral at that point or in the panel would cause these 2 circuits to be in series across 220v. Are any lights or appliances running too hot or bright or fast as well?

Probably those useless "stab in" outlets.
