    Communal DB does it require RCD protection to be a sat EICR

    Think this is the relevant point. When I queried a similar scenario with Napit technical a year or two back I was advised that the communal lighting was not necessarily domestic in which case you are only coding for cables being less than 50mm deep (if that is the case).

    UK Change in current capacity along run

    Don't think it says change in current carrying capacity, doesn't it say change in conductor csa (which will affect current carrying capacity? There is a 3m rule for backfusing in this circumstance

    UK RCBO Testing

    Make of rcbo? Some (MEM?) were known to not trip when testing at their output terminals but attach even a modest length of conductor and test from that and they behaved.

    UK EV charger

    Looking again the conductor coming from the lh fuse and the lh n appear to be in heat shrink as does the earth. Looks a bit 'home made' as though singles may have been used and the heat shrink is there in an attempt to make the tails double insulated. Doesn't explain the earth though

    UK EV charger

    For clarity, the issue with a looped supply is that two supplies are connected to a single terminal in the cutout which is rated at 100A. Taking diversity into account this was considered acceptable. However with the advent of EV charging the loads have increased significantly and the 100A...

    UK EV charger

    It doesn't look like a looped supply but it is a bit unusual. Your supply appears to be the right hand fuse, the left hand fuse supply goes through the wall (to your neighbours?). It is probably worth contacting your dno to get them to come round for a visit as it looks as though your...

    Upgrading my service from 60Amp to 100Amp

    Either you or your electrician need to contact your dno to ask about increasing the supply fuse, neither of you are allowed to make this change, only your dno can. In my area you will only get an 80A max and that is if local network demand allows this. Whilst under our regs 16mm tails shouldn't...

    Milwaukee M18 Fuel!

    If you are impressed with the Milwaulke fuel 18V impact driver, wait until you use the Milwaulke 12V surge impact driver. It is hydraulic, quiet, controllable and powerful. Cracking bit of kit, only problem with it is that I now have a spare 18V impact that no longer gets used

    UK TNCS CPC not used

    Is this a property on it's own with it's own transformer?

    PME Supply Advice

    You do not link the E to the N, we are not allowed to do that. Whole thing sounds unusual, first port of call should be a call to the dno with an earthing enquiry. In my area they are extremely helpful

    UK Shared income supply main fuse

    Are you an electrician? Looped (shared) supplies are not uncommon although your cutout is not one that I recognise. From the photo it is impossible to tell whether the feed to next door is taken from the supply side of the fuse and then fused next door or if it is taken from the load side...

    Becoming an electrician

    I am the dad of a dno band 5 technician (plus an electrician myself). Career progression within National Grid now effectively requires a large element of technical qualifications (HNC etc) which you sound ideally suited for, you can study whilst working. I find what my son does quite...

    Gas meter 'vs' SWA cable proximity

    Pretty sure there is a gas reg that states the gas shouldn't be within 150mm of the electric incomer, other than this instance I think the 25mm guidance applies. I was told that these rules are to do with arcing which is unlikely to be an issue with swa

    What is wrong with my new TV ariel Installation plz?

    If you are not lucky when adopting the 'just put it up and see what happens' approach then you will (ideally) need a uhf signal meter. As Brian correctly states above, it is not just strength that is required, the signal quality is paramount. Have you got the polarity correct (flat for main...

    Isolators in meter boxes

    Now I know I have family connections with NG (Western Power as was) but I have just formally asked them to quote for replacing a surface mounted cabinet with broken hinges and broken fibreglass where it should latch, it is an unusual cabinet in that it is not the type that is currently used or...
