    Should these tails be mechanically protected?

    Hi guys. Im moving a consumer unit for my brother and where I was going to run a 25mm armoured through the building he has decided to put a window directly above the cut out. After explaining to him the only way I could do it would be to put a piece of earthed metal trunking on the inside (red...

    Mix of 16mm and 25mm Meter Tails

    Hi, Just had a new Smart Meter fitted yesterday along with isolator. The chaps installing the SMART meter used 16mm tails from the main DNO fuse cut out (containing 80 amp fuse) to the meter, but then used 25mm tails from the meter to the newly installed isolator (which they also installed). I...

    Tails inside consumer unit bare copper, not terminated correctly - C1 or C2 ?

    Ok, I'm in the middle of an EICR for a client. The tails are going into the consumer unit in separate holes (It's metal, so that's against the regs), and then inside the consumer unit they have been terminated in a really shoddy way with bare copper showing. Now copper showing on the tails is a...

    Additional consumer unit - tails in trunking - how?

    I need to install an additional consumer unit. Normally I would put the existing tails into Henley blocks and feed both CU from there, but in this case there is an isolation switch, and the output tails are in metal trunking from the isolator to the CU. The new CU is going next to the old one on...

    UK Thoughts on Meter Tails Install?

    I’m rewiring a massive house and there’s a feed to a c.u in the old black rubber cable that needs replacing. I know that Meter tails follow the same guidelines as other domestic wiring, but i’m trying to avoid putting a rcd on supply end of the tails. The run is about 20meters long and going...

    Can you extend meter tails inside a consumer unit ?

    ...and why would I want to do that ? Well, I'm faced with a real botch job of a consumer unit. Essentially this is a "new" consumer unit only put in a couple of years ago by a friend of the clients family who was apparently an electrician. However the unit they bought (a Niglon) had the main...

    Hi, gone to look at a board change job, it’s an old re-wirable fuse box less than 3m away from DNO and ran in 16mm tails, 10mm earth and no bonding to the incoming gas pipe and customer has no idea where the water comes in as the house has no stop cock. I will be putting a dual split rcd 100a...

    16mm tails insulation

    16mm meter tail cable has a double layer of insulation. What do all think of removing the outer layer of insulation, to make it flexible, when the cable is being run entirely in plastic trunking.

    25 mm tails as a CNE conductor

    During an EICR i have found from the ryefield to each cut out wired in 25mm tails . one of which is used a CNE conductor which is then split in the cut out housing to form a usual PME supply TNC-S. i guess this was done by DNO or BNO . is this safe and acceptable ?
