On WPDs network, every joint on the main has to have a ‘pigtail’, a coil of copper wire left in the ground. Apparently they don’t put rods in any more after a few near misses!

Looks from it position probably the neutral bar has got a bit hot and started to melt the case. Probably a bad connection. Rcds won’t trip for such a fault necessarily. What make is your consumer unit? let us know what happens when your electrician turns up

Ring them back and say you have no electric now? Or it’s on fire. Though they’ll probably just say ‘ring the fire brigade’!

I would say your electrician doesn’t have a clue. As others have posted, the ryefield board or the Lucy equivalent. Be prepared you will possibly have to arrange meter operators (for potentially all four meters) to reconnect their meters to this new board once it has been connected to the...

The issue you will have is any decent engineer won’t recommission your old boiler as it won’t comply, and by that you wouldn’t have the required paperwork to satisfy building control.

I think a removal and reinstallstion is classed as a new install. Otherwise everyone would be fitting second hand boilers to circumvent the regs

A non condensing boiler would not comply so think in this case you would have to replace it As you are not Oftec registered you would have to notify building control in advance (no probs as they presumably are already involved) and you will most likely have to get an Oftec engineer to...

that’s up to your electrician to determine that you won’t overload the available supply. You do also have to inform your DNO that you are proposing to connect an EV charger to their network

do they know it’s for an EV charger? Normally It’s a chargeable job but I believe for ev and renewables it has to be done for free under ofgems R110-Ed1 commitments

I have seen mostly as described, terraces and back to back under the stairs usually in semis Have also seen three together on one loop, where they looped through the front gardens, in this case not sure why they didn’t take each cable back to the road have also seen houses looped in pairs...

depends how the ‘loop’ part is run. If it goes back out the house and into next door then, it would be cut near the house and jointed to a new cable from the road. Or even near the boundary to avoid disruption to the neighbour. but yes if it runs internally to next door (terraced house or back...

As far as I have experienced it applies to either end of the looped supply

There’s a few ways that they can do it. I’d leave it to your DNO to sort, they can deal with all the arrangements with the neighbour. They must have been some of the last to be looped, not a permitted practice anymore, definitely haven’t come across any fitted later than around 1998

As far as I’m aware, regardless of fuse size, an EV is not permitted on a looped supply, of any size. Certainly in my area, Western Power will ‘unloop’ the supply for free

Proteus - say no more. See more of these burnt up than working

Yep well within my area. Feel free to give me a shout

Where in the west mids are you? I’m fairly local and prepared to give you my opinion on the job

But that scenario has many issues, which I have no control over. Like interfering with the cutout fuse and failing to do any initial verification before energising, ie an IR test. I think I will leave the SWA disconnected both ends, heat shrink up the ends, tag it and issue in writing it is not...

it wouldn’t make a difference no, if he’s going to do it I can’t really stop that, but if I lock it off and document this, should anything happen, then at least I would have covered my back

So when a HV cable is shorted to earth to be worked on that is a criminal offence? sometimes I terminate a circuit I am working on deliberately into the earth bar at the distribution board. That must make me a criminal
