A periodic inspection report is recommended by the scheme providers, before changing a distribution board, this should detect most latent defects and departures from BS7671. As this report can take 5/6 hours on an average domestic 3 roomed property, the expense of this report is not usually always accepted by most. This would result in any latent defects, being detected after a board change, there is then a justified, additional cost for remedial work. The options should be spelled out to any potential customer. Sockets on ring mains can have loose connections, so giving high ohmic readings etc., these would require to be corrected before connection to the new board; or alternative measures taken to make the circuit safe.Hi forum users,
After having conservatory built on back of house we have had 1st fix of electrics installed, had to have a new up to date fuse box installed by same sparky as we had the old style. That's all in and working, he said once in he will do tests, it's come back saying we have a dodgy plug somewhere, he has given us the option of either a days labour charge or to charge per plug. If he found the faulty plug at the beginning I'm quids in, however if it was the last plug it will cost an arm and a leg. He spoke to my wife about this as I was at work but said only way of finding fault was to remove each socket and check wiring??!! Surely a plug socket tester is easier solution??
Any thoughts from you ppl??
Also he said my mains water is not earthed nor the boiler so is quoting to do that, is this important to be done?
This lack of bonding to the mains water should have been seen; and allowed for at the time of quoting. It is not usually necessary to have a separate bond to the boiler, if the main bonding is in place; electrics to the boiler should have their own circuit protective conductor within the serving cable.
