Can a circuit have power with the switch off ?

we have a light switch, when on, the lights are on. When off, the lights are off, but the light flashes on about once per minute.

We suspected there is still power in the wires.

An electrician said there is 20 volts lost across the switch, so he changed the switch.

But the light still flashes in the off position. So he just changed the bulb, and said the bulb was the problem and left.



But we just think the new bulb(efficiency bulb) was just not as sensitive as the last efficiency one, and that power is still draining out somewhere.



Is there any danger if we have power seepage like this, or is it common in home wiring ?

As an electrician for 25 years I suggest you change electricians instead of the bulb.I think,not being there that you have a back feed from another circuit or your neutral and your hot wire is crossed.

its not really common theres somethin there thats not right
it could be that your hot wire is touching ground.. maybe exposed wire screws need to be wraped in electric tape, and also try to changing the switch..... that could be bad!
Sounds like someone got their wires crossed. There was a problem with mice chewing wires in the attic of a house I lived in and I had a similar problem till the mice chewed the wrong wire and got juiced. ICK. Got it fixed and had dead mouse removed and baited to get rid of any other mice. No problem after that. You should call someone because you never know and it could start a fire if there is a short.
its not common if the switch is off than no power is going into the light bulb



poss able cause's



1another light is in series with that one

2 bad switch

3 floating neutral
If you are repeating what the electrician said and did, then I agree with another answer you have; you need another electrician. He was drunk or stupid. %26quot;Power seepage%26quot; my foot! More like a short or defective component.

Call a licensed insured elect. (immediately) hopefully that has worked for someone you know. Don't be cheap. When a fire reported in the news, what's usually the cause?...electrical.

I have seen flame travel a wire burning the insulation; seems like the speed of light.
you probably have a loose connection, or a short.
