Circuit breaker

[Howie]

I am switching my light switch in my kitchen when I turn off the breaker all the power goes off expect for one light that is still on. I tried turning off the other breakers but this particular light still gets power. Should I try turning off the main breaker switch to see if that works? Can this light be hooked up without connecting it to any of the breakers? Or do I have a bad circuit breaker? I tried switching it one by one thinking it might be with another breaker but none would turn off the problem. Do I need to call an electrician?

I would advise to call an electrician, as this does not look like a problem a homeowner can easily resolve on their own. Where exactly is that light that refuses to turn off? I never encountered a situation when a light is powered from a circuit, not protected by a breaker. But there can be several situations that may lead to this happening, one more dangerous than the other. If your breakers are actually breaking neutral rather than live end of the circuit, you have 240V service in the home, and the light is fed by the voltage difference between the two hot wires of 240V, it will never go down. But the more I think about it, the more crazy and the more dangerous this kind of mis-wiring becomes. Could previous owners be stealing electricity by having some circuits connected bypassing the panel/meter?

Definitely call the electrician! Whatever the reason, none of the potential fixes sound DIY to me, Be safe!
