40 volts at one elec outlet
House is ~50 years old. Copper Wiring. On one 20a circuit there are a
number of duplex boxes. On three adjacent to each other the voltage reads 120 -- ~40 -- 120. The previous owner switched one box to a single receptacle and switch. And wired to the switch a lamp (incandescent) in a new skylight. The operation of which has always been problematic. I tracked down the low voltage recaptacle when I move the refrigerator plug to that outlet. Any thoughts on this? Thanks. |

40 volts at one elec outlet
You're probably reading the voltage thru the filament of the light
bulb. Something has been wired wrong. Rip it apart and check for normal wiring. If you cant do it, call an electrician. The black wire from the source should go to the gold screws on outlet, white wires to silver screw. The switch should be connected internally to the switch (if this is a switch outlet combo). The wire to the light should go to the screw closest to the switch, the white to the light should also be connected to a silver screw on outlet (or wire nutted together). If the light is problematic, either the switch is bad, or the fixture is bad. Replace both and get the job done. Otherwise, do one at a time. This is pretty basic wiring, if you dont feel competent to fix it, get a pro. On 10 Jan 2007 08:28:24 -0800, "Don't Wait Up" wrote: House is ~50 years old. Copper Wiring.

Are you using a digital meter? I suspect that outlet may not be getting any current, but still will show voltage on a sensitive digital meter. A quick check using an old analog meter would tell you what is happening? -- Joseph Meehan Dia 's Muire duit |

IMHO, not your electrician, you have a wiring problem, that should be looked at. Low voltage conditions can be detrimental to your equipment. Now if I was there, my first step would be to toss in a circuit checker. The proceed on based on the results. Good luck, tom @ www.MedJobSite.com |
