Cheers for all the replies. I had a look at the flat next door and they've had new tails and 16mm main earth ran through the building. The flat above has has an SWA ran up to it and no separate earth so looks like everyone has taken a different approach.
I've left it with the customer to ask /...
Cheers guys.
TNCS at the main incommer downstairs. Then fed up to the flat via a 50a MCB via what looks like 2 x 6mm T + E
Ceiling and floor are concrete
If I can / just change the board and leave the lighting circuit alone then I'd have to notify the customer that they can't change to metal...
Hi all,
Just recently set up on my own and potentially have a flat re-wire to contend with. Customer has just moved in and wants to get everything right before decorating etc.
The flat has gas central heating so no need to worry about the old storage heater wiring. Only 4 circuits for the...
That's why I was leaning more towards running the final circuits from the sub board on 20a RBCOs so that a short / over-current on one circuit on one of them should take out that instead of the 32a back in the main board.
Sorry should have said.
20m from the main board. (so not that far if I'm honest)
Would still like to do it this way as the RCBO'sI would install would be easier for the guys to get at if there was a fault.
I come across this one quite a lot. It's not ideal but if the customer really doesn't want the circuits segregated and you've already changed the board I'd put them both on one RCD and MCB as telectrix said. Not ideal but better than having one circuit not protected by an RCD.
Hi all,
Company I work for have moved into a new factory and asked me to wire up the work benches, properly this time as before they just used a selection of extension leads dragged across the floor.
Anyway. On the wall there is a 4 core 6mm SWA cable terminated into a rotary isolator fed...
Hi Midwest,
I know what you're saying and it worries me, hence asking for advice on here. The problem I run into is that there doesn't appear to be a BS for the products we make. There is a document on the government website that is very informative but just states that the equipment has to be...
Hi mate,
If I'm honest I don't anything other than a PAT test is carried out, and I'm not even sure they are doing that. I don't really have much to do with the manufacturing side of the business but I'm just poking my nose in because I'm slightly concerned.
We essentially just wire...
BS 7671 is the requirement for electrical installations, not the equipment attached to final circuits.
Thanks for you replies. Will get the calculator out and try adiabatic equation on the current set up. I've been looking for a definitive answer for 3 years now, I don't think there is one!
Hello all,
I'm sure someone on here will be able to help me.
The company I work for manufacturers electronic signs, ticket machines and information kiosks. You'll see these dotted around the UK in stations and bus shelters etc.
I joined the company 3 years ago and although the products are...
Hi Voltz,
Thanks for your reply. I'm not mad does that sound bad to you? I'm going to go back to the company with the findings, just wanted to double check with people on here first. Worst case scenario there is a perfectly logical explanation and I'm wrong but it doesn't sit right with me...
