As the tittle suggests really. Starting the Strip out on a 4 story office block tomorrow and starting to design/price the new install. To comply with part L2 I want to sub meter the lighting and small power separately at each DB so was wondering what are others preferred choices. I usually use...
How would you code for circuits not protected by RCD in HMOs, the circuits being, lighting, water heaters and storage heating?
I'm thinking code 3, my main concern is the switch drops having no protection, just wondered if others agree.
Hi whilst doing the split method insulation resistance test.
After opening the mid point socket,whilst putting 500v through one of the legs are you supposed to leave the other end in the mcb and if not do u terminate it?
Due to a burnt out 80a rcd on a wylex split board consumer unit, the consumer unit now only has one 80a rcd which all circuits (mcbs) are wired to, so a new 80a rcd has been bought to reinstate the split board. The issue is that the original live and neutral cables that linked the mcbs together...
The usual C.U. change problem.
All circuits working except one (Ostensibly a ring circuit, once upon a time. It 'end-to-end's at the board) which seems to have a neutral to earth fault.
I was methodical so I don't believe any neutral conductors were misplaced, but even putting the two...
Hi,
Got called to a jobs due to the RCD tripping on the downstairs ring, as soon as the MCB for the ring is turned on the RCD trips.
I didn't have long but I did some quick tests, R1+R2 was fine on all sockets so I split the ring about half way and did an IR test on each side of the ring and...
Where do we stand with an EICR and a split consumer unit. Obviously some circuits do not have RCD protection. Is this a code 3 as nothing is being added to the circuits. Clients aren't happy that they have a relatively modern consumer unit and they have to spend some of their hard earned money...

Looking for a bit of advice here. Just started doing work at a large hotel recently and the wiring is a bit of a shambles but the owners realise it's been bodged for years and are willing to spend the money required to put it right as we find it. Got called today to say a resident got a shock...
Job I've started today, its a big office just off parliament square London that's now being split in to two, new DB, sub meter, floor sockets and lighting being split to the new corresponding sides etc.
The landlord had a sparks in to change all the 600x600 fittings for led panels and add some...
Hello all. A friend of mine is looking to buy a house and got me to have a cursory look at the electrics for him. One thing seemed a little peculiar but i'm not sure whether or not it'd be deemed unsafe when he gets the EICR certificate done.
The Consumer Unit is a fairly recent looking BG Dual...
Hi all, towards the back end of last year we installed a new modular building to be used as a village hall. The spec required split metering, (power on one meter, lighting on the other). so we fitted a hager split metered TP&N DB. Recently the clients have had their electric bill stating they...
Hi Folks,
Just a quickie, that you may know instantly. Are split load 16th edition 5+5 Starbreaker boards changeable to 4+6. Need an extra way on the RCD side if possible and not too familiar with these boards. They are the plug-in type breakers.
Had a look on electrium but no joy thus far...
Just met a friend of my long time mates tonight and was warned she had a split personality ... It was one of the weirdest experiences in my live..... one minute we are talking normal sounds really sweet then all of a sudden she switches to a defensive argumentative mad women :ack2:... her mates...

Hi All,
Having a little discussion with my old man over a job. The job is a domestic property, the CU is around 7 metres in cable length from the meter. There is a switch fuse around 4m from the meter, in a cellar. However, the tails are run very shoddily in an old bit of water pipe and then...
Could I have as much info regarding split phase installation complications to a new farm dairy unit I am going to be starting soon.
what I've heard so far:-
you should not switch neutrals on split phase circuits
how is volt drop calculated on 480v supplies for sub mains

Builder customer of mine has asked me to put 2 cold tv ' s on the wall , there are about 4 or 5 of them in an office where they share a hard drive.
They want to use a timetable programme, where they can all access and change things (dates/times etc.) , they want this to be displayed on across...
Hi peeps,

Can one of you kind people please advise me as to how I can...
