We had a new electricity meter fitted last week, being a 3-phase supply at home, it had to be done as a 'special', but it all went OK. The new meter has two built-in mobile phones, one to change settings and one for the billing.
No problem, instead of quarterly payments we are now on monthly...
When the engine was doing the change-over, I queried the seemingly incorrect labelling of the tails into the meter and switchboard, which had coloured tapes AND tie-on labels which disagreed, and sure enough, when he checked the new connections, the labelling on the main incoming fuses was wrong.
The outgoing leads to the meter had been changed to make the phase rotation correct, rather than making the incoming termination right.
So, we now have some interesting wiring between the main fuses and the meter, and we have changed the labelling on the main fuses to "Blue Red Yellow" from "Red Yellow Blue".
That original installation was done by East Midlands Electricity engineers.
Makes you wonder.
