I bought a new MFT1710 a couple of weeks ago and got a free clamp meter with it. (UNI-T UT210B, 200A Mini Clamp Meter).
I finally got it out the box today and thought I'd try it on my mains tails to see if/how it's working. Surprisingly, with the consumer unit main-switch off, and the main...
New position of replacement Consumer Unit for my customer is now going to be 7m away from the supply head. DNO fuse is 100A BS1361 and this is a large house so I still need a (potential) 100A supply. I believe that I am supposed to fit a switch fuse if tails are over 3m long. Firstly, am unclear...
Hi, any suggestions for connecting the tails from the metering equipment within the meter cabinet to armoured cable. (Domestic property). I have seen a clamp used before by a new house builder, but I have been unable to source one.
Cheers
Hello all.
About to do a CU change and from the pre works visit it looks like the 16mm T&E from the meter is run 3m to the CU behind the skirting board. No mechanical protection seen. TNS. Ze = 0.28ohms.
This clearly isn't acceptable and I shall advise getting it changed but my question is...
Why cant I get the same pliable cable for meter tails that SSE uses the stuff I get is as stiff as rebar whereas theirs is really bendy and easy to form if any one knows why this is let me know
P
Ok own up who's done this?
I try my hardest to never do this but have, on very rare occasion installed meter tails in a cavity as the lesser of evils.
Would be interesting to hear real world thoughts on this and potential work arounds so you don't have to. I know someone on here posted a while...
This has come up many times before and after a couple of hours reading previous posts I'm no closer to deciding on a code, note or nothing at all.
BS7671 allows 16mm tails on 100A fuse if demand is less than the cables CCC, I have 16mm at 94amps and the max demand is 60a.
From a previous post...
Hello, anyone know when the regs recommending a switch fuse for meter tails greater than 3m long was introduced ? On older installations (about 20 years ago) was a switch fuse required on tails over 3m ?
Thanks
HI all,
got some tails to run down a wall, i can and will run with 50mm depth but would also like some channel to protect aswell, seen some on another job, bloke said it was tophat channel or something like that said it was from eddy's.
done a google search but cant find it, any ideas?
cheers...
I need to upgrade my meter tails to 25mm. The existing tails pass along under the pebble dash in plastic conduit (which would be too small), then apparently at an angle through the porch structure (unprotected) then turn sideways into a void & up the void to CU.
I have seen other posts where...
Ive been asked to look at the electrical installation at a large 5 bed property with an attached annexe that the owners are converting into a 2 bed holiday let.
There's one supply cable that comes into the annexe for the entire property .
This is currently routed via a single meter to a CU .
2...
Just a quickie, if the cut out fuse and head is rated at 63amp can you still use 16mm tails for a 6way board. The reason for asking is, I have to change a board in a old flush internal metal cabinet and there is next to no room inside due to the meter and cut out taking up most of the space, its...
I have been going over this for some time, and every time I think I have it sorted I read something else which sows doubt in my mind again!
TT system.
CU to be replaced and moved to new location as not enough room where currently sited.
New location will result in tails being approx 5m in...
Evening all, been a long time since I posted on here but I could use some advice if there's any going!
I've been asked to provide an EICR for a small building we look after for our client under contract. We are all done physically on site, but I've hit a snag filling out the report itself, in...
Had a look at a job last night and the customer had another electrician bury the cables with a bodge method of protection (they were planning on plastering over them as they are) (image attached). The tails run from the meter (out of view at bottom floor level), up into the ceiling and to the...
hi all any advice on the following scenario much appreciated. I have taken on a rewire from another electrician whos personal circumstances mean he cant finish the project. Majority of the first fix has been completed including the repositioning of the DB. The original DB was situated inside the...
I'm looking at a job for a friend and wpd is upgrading his cut out and wants us to upgrade his whole install. my question is from the new 315a fuses wpd is putting in what size cable would i require to the panel board literally decide it.
I've has a look on like and uk power networks suggest...
