newly installed lights not coming on
I have fitted some new light fittings in our living room which fail to come on and I am not sure why.
The wiring is the same its just new light fittings replacing. I have also fitted a plaster centerpiece so I have drilled a few holes in the ceiling but I did not feel like I hit anything while drilling.
The lights do not come on but the breaker switch stays up?
What would possibly cause that?
