Full rewire - Avg terrace

[Roadhousezamora]

Yeah the t+e running up is attached to a 40a RCBO and is running the upstairs shower.

The pics I've posted are just to supply temporary power whilst I complete the rewire. As the property will be unoccupied I'm just going to remove the three boards and fit this until I'm ready to energise the new permanent board. I'll then take this one I've built with me and reuse it on the next property.

From what I can gather of the boards that are currently there, everytime something has been added it's been put in via a new board instead of paying to redo it as one board.

OK, that makes sense.

Not uncommon. Sometimes because the old board has no space, sometimes because of a big gap in time and you can't get compatible parts for the old board so easier/cheaper to put a new one in, etc.

Always have some space for expansion! The cost for a bigger CU is usually trivial, as it is the RCBOs, etc, that add more cost (but even then, probably less than cost of testing, etc).

Forgive me asking a side question about your board. Is that a 16A male and 16A female socket both connected to a circuit from the CU? I fear you slightly misinterpreted something I said....

If so, you need to lose the male, as you can't have 3 live pins just sitting there.

You can use that arrangement with a socket on it's own, so the male is where the power comes in, and the female is where you can daisy chain to another board.
You can also use that arrangement as the incomer to a whole board, again the male is where the power comes in so is never live unless being used.
But you can't have a male socket live just sitting there.

Sorry if I'm wrong.

Thanks Tim, it would appear I have misinterpreted, I do get what you're saying. The 16a male socket could be used as an incommer socket for a new board in a different location and shouldn't be wired as an outlet as I have done here.

I will grab some more 13a outlets and fit them to a new board with the 16a male as the incommer and run a 16a male to female extension to it from the outlet on the board pictured here. That second board would then provide power upstairs during the work. I assume as you said originally I could continue this process on to a third board by fitting an outgoing 16a female socket? I guess this is what you were meaning in the first place... I'll get my coat

I will remove the male socket and shove a blank grommet into the hole.

It's these sort of things I definitely need to be told, you definitely don't need to apologise.

Yes that is exactly right.
The 2nd board doesn’t need a CU on it just a socket in, 13a socket and socket out.
(It also doesn’t need a board, you can use a short length of flex rated for 16A and trailing plugs each side, male and female.)
It’s looking good though, very neat!

I'm not sure but those old mem boards could be the type with the asbestos arc pad in the holder, the fuse itself looks familiar... maybe somebody can confirm, maybe just hold your breath when removing

I hadn't considered that and you're right, it could well have, I will see if any others advise. I think the mem board you mention is board mounted so will try to just remove the board from the wall if possible.

Cheers, I see how in the future I could add further 16a RCBOs and female outlets to run other satellite boards around any future properties.

If the fuse carrier sitting on top of the consumer unit is the same as the fitted carriers then they have BS1361 fuses fitted so no asbestos. These are Memcert fuses and the way to tell without removing them is the hole through the carrier body, this indicates BS1361. No hole will almost certainly indicate BS3036 and the likely presence of asbestos.

Just for academic interest this style has the asbestos in the fuse carriers:
