Hi all,
got a strange situation at home:
the upstairs lighting ring is off (no lights works), but the circuit
breaker covering that ring is still on (all the circuit breakers are
still closed).

We're in a 12 yr old conventional house, and had our fuse box moved
about 9 months ago. We have no other electrical problems - to my
knowledge.

My wife replaced a bulb the bathroom last night, after which the
lights worked fine. This morning the lights just "went off".

Hey, I'm stumped.

Any suggestions?

Ian.
