Hi

I was removing a ceiling lamp because of painting.
There was contact between the ground and the live wires.
After that the bulb burned out, but the real problem is that the majority of the lights on the same circuit do not work now.

Curiously after the bulb burned,
Trying to wire together the live and ground wires fixed the other lights.
But that was not the solution I thought.

Called in an electrician who spend few hours checking connections, but could not find the problem (the other lights not working problem).

The electrician said that all non working lights had an open neutral and that tracing where that happened it would require checking each point in the circuit from the fuse box.
Even though he did check the most probable points (almost all of them).

Does this make sense ?

Please help

I would suspect open neutral in ceiling box location. Also may be on a Multi circuit(2 hots sharing 1 neutral). It is perfectly safe. Except if neutral opens, those circuits may reach 240 Volts(the lighter load will receive the most voltage), Maybe why bulb blew. You may have to turn off 2 circuits to work safe.

Hi Stratmando

Forgot to mention that the ceiling box is the end of the circuit.

So anything wrong with it, it should not affect the other parts of the circuit.

But on the same time when I wired ground with live the rest of the circuit worked ( so this box affects the rest of circuit! ).

Very strange to me...

Maybe when I was playing around with it something else broke in the circuit, where now many lights have an open neutral.

I would start at other end, first bad light, or where switches are. Could be at main panel, if you know what circuit it is, follow from breaker to where it leaves Panel, and check whites that leave with that hot
