Hi all, what are your thoughts on running new tails from an outdoor recessed meter box,straight through the existing hole into the garage where the CU is situated. Should the hole be enlarged to accommodate some sort or trunking for protection and sealed for fire??? The tails are connected to a...
I'm working in a warehouse and replacing the old fuse boards with a new 3 phase board.
The board will be sitting directly above the buzz bar im not sure if I need to put in an isolator in between them to isolate the 3 phase board?
Thx
Hi. I've recently moved into new house. The meter box and consumer unit are installed in cupboard underneath the stairs, however they are approx. 1.5m apart and the tails are surface mounted. Should they be encased in trunking so as to protect them from damage. Thanks
Hey guys. Wondering if anyone has came across this before and if it is legal? It is several 1.5mm single cores going into the neutral of the main switch. Main fuse etc is several metres away in communal hallway, but is a 16mm meter tail from there.
Cheers
I have a job where SEC are moving the mains cable for the property to allow for change of use of the area. This means that the tails from the new meter box will be through a wall and over 3 mts long. Therefore a Switch fuse /isolator will be required in the new meter box. Does it require the...
Hi,
On site dispute needs sorting.
We have a consumer unit 3m away as in distance (not cable length) from DNO (outside meter box, flush with wall).
We currently have a 25mm 3 core SWA from DNO to consumer unit. Running within the fabric of building and it's protected from the nails and the like...
Quick one.
Tails are 10mm. Earthing cable from rod to earthing block inside the CU is 16mm.
Where i am, we have the tails in, everything RCB protected and then the earthing cables from the circuits/appliances etc into the earthing block. On my CU, the earthing block is a bank of 'quick...
hi everyone,
I am sure this has been discussed many times but what do people think with regards to upgrading the fuse board tails on a consumer unit change? I have one to price up for a flat where the meter cuboard is outside the building, and the tails are run through the hallway up a riser...
Been to a job to see this. I'm guessing that when the old CU was replaced the sparks didn't bother to remove the old meter tails - they were live and just had a couple of wraps of insulation tape round them.
I seem to have a run of jobs of upgrading consumer units. Previously I've used 32mm standard stuffing glands for the tails when I have needed to. Although the sealing gland hasn't got specific holes for the tails i find that it seals well.
Anyway I've been looking at the special tails stuffing...
Hi all some advice will be Much appreciated please when filling out a eicr the primary supply conductor would that be the main supply cable coming in to the building or would it be the submain of the board under test in a commercial/industrial installation as going through others eicr and...

I know I have started another thread in the past with an almost identical title but this one is asking different questions!
The DNO are moving the meter box and I will need to extend the tails to approx 8m.
The present earthing arrangement is TT, I have asked the DNO to change to TN-C-S and...
Hi All,
I have my ELECSA assessment in a few weeks time. I was going to install an in-line water heater at a friends house but am now considering a board change at another friends house as this seems to be what they really want to see.
I am trying to back up everything I do with regulation...

Say you were going to change a CCU, and it is an 80A fuse with 16mm tails (10mm earth). Bonding is in place in 6mm. What would you do with regards the tails and bonding? Been thinking about this scenario all morning and it's bugging me now. I'll walk you through my thinking, would appreciate a...
