Hi,
We are getting power cuts to our house. They see to be associated with switching various pieces of computer kit on in the office but there is no consistent offender, and all the kit has been running perfectly in the past.
The odd thing is that none of the consumer unit thingies trips, it affects the whole house, the disc stops in the meter and anything from 5 mins to an hour later the power magically comes back. Also, the lights start to flicker just before it goes completely. Even of they were on and constant up to that point.
We've had the electricity supplier out a couple of times, but sods law is that the power was back when they came and they couldn't find anything. They measured the voltage at the meter for a couple of minutes and said it was fine.
Possibly irrelevant, but in July we had a new boiler put in, relocated from another place in the house so there was a fair amount of electrical work. The electrician said the house earth reading was way too high and the power supply company came and did something out on the pavement to restore the earth reading to close to zero.
I have 'caused' a cut when the boiler and central heating master electrical switch was off.
I just don't understand what's causing the whole house to lose power, and also what's causing it to then spontaneously come back a few minutes to an hour later.
I'd be very grateful for any suggestions or ideas on what it can possibly be. (I've got an electrician coming tomorrow lunchtime, but the work is piling up and every time I start the computer the power goes again! I do have a UPS, but the spikes (or whatever) when the power is going seem to cause it to shut down immediately.
Thanks!
Pete
