New rewire and fuse board - views on work.

[Debrahim]

Hi,

I’d appreciate views on the fuse board.

It’s been completely rewired and I’m unhappy with the quality.

I’ve messaged him about it and described the board as a complete mess, and poor workmanship ship. For entry for the 25mm cables and 16mm tails he used the knock out but didn’t bother using the plastic cable holder - which is a couple of quid.

Also with the cables coming in through the back, there is no plastic or anything so the metal of the board could rub against the metal of the board.

his reply is below

a. - there is a reason why cables shouldn't be perfectly arrange in the fuse box because it could create electromagnetic field resulting in humming sound in the fuse box- you would probably think that's ridiculous ! But it's a fact!


Quite frankly I’m shocked, would you be happy with the work, paying over 4k? And supplying the board all second fix items etc? So basically 5k?

He has also created 5 additional lighting circuits downstairs, I live in a three bed terraced house.

1) for 6 down lights in a 2.5m x 2m room.
2) just the ground hallway light.
3) the lounge dinner, two lights and two wall lights.
4) a porch light and floodlight.
5) under stairs light simply 2 lights.

His reply is that it is is better… but then it’s all on a dual rcd so it doesn’t really help in my opinion.

We agreed the whole of downstairs on a circuit except the hallway on a separate one. (He said that was best practice.

I’ve attached photos and the pieces that I believe should go there. One is too big.

Yes it doesn't look great and dual rcd consumer units are not recommended for residential installations. Has this been done by an electrician or a builder who think they are an electrician.
You say it has been completely rewired yet there are cables with red and black cores.

Assume that's the before it was rewired ?

8 circuits on one RCD - that's not good.

Decent quality board though. And an SPD fitted.

Cracking excuse for untidy wiring - it avoids electromagnetic interference making the fuseboard hum!!

If those cables lashed down the wall is the 'finished job' then I would not be happy

Needs some plastic trunking and a good general tidy up

I’ve noticed this and have pointed this out.

He is a niceic registered electrician which I’ve verified with them.

I’ve also noted that if the fuse on the right goes I will loose both power and lights to the upstairs and third floor (loft).

As an electrician would you be satisfied with the standard of work ? He deems it good quality and states he’s been registered for 15 years.

I’ve checked on the website, he’s part P. I found him on my builder with over 100 reviews and 100% positive rating.

You say dual rcd is not recommended. If im honest I didn’t want to spend the money on a rcbo- there are 14 circuits.

If I wanted to change this to a rcbo, could I simply buy the rcbo’ or would I need to install a whole new board ?

Is it possible in this fuse board to add a third rcd, to split some of the stuff, in case one trips etc ?

Or even is it possible to put an rcbo in there? Obviously I know it would need to come before the RCD.


Perhaps just for upstairs sockets so we have some power in an emergency.

no this is after the rewire.

This individual should not have installed a dual rcd consumer unit and the fact there are cables with red and black cores indicate it has not been fully rewired.

The board has 3 neutral bars, so it should be possible to fit one or more RCBOs between the main switch and the first RCD.

But one more comment - the board seems pretty full. It is good practice to leave several spare ways for future use, for the stuff you might need in the future but haven't yet thought of.

 

[Debrahim]

To clarify he wanted to supply and fit some crap board.

I BOUGHT the HAGER board and chose it with SPD protection.

I agree that there are too many circuits on the one RCD.

I’m refusing to pay him the final payment - he is going to come around and sort it.

The Idea was to have several spare ways but for ground floor lighting he has used 5 circuits !!!

There's nothing wrong with having lighting broken down into so many circuits, although it is very likely to be pointless. As you've stated, a fault to earth will take them all out, along with every other circuit protected by the same RCD.
