Judging by the state of the wiring you can see here, I guess it won't come as too much of a surprise that I received a call yesterday to say that two of the fluoro lights at the end of the central aisle had stopped working.

By the time I investigated this afternoon, they were back on, although I was informed that they had done a lot of flickering on and off while "making noises" before coming back on fully.

Turns out that the neutrals in the terminal block of the upstream fitting were loose (as were the screws holding it to the ceiling).

I also found that the ground wires on the incoming and outgoing cables had been connected together, but were not linked to the ground terminal on the light.

Who knows what other problems lurk in this lot? [Linked Image]
