Use of 60 amp Junction Box

[Stevie Wonder]

Sorry this is a general question but for some reason I couldn't start a new thread in the DIY section;
Anyway here's my question:


I have recently had the consumer unit in my house upgraded from an od 4 way wylex to a MK 10 way RCD split protection etc,etc.
to do this the electrician had to alter the ring mains etc which is great however my concern is that he extended the shower supply (6mm t&e) by joining the existing and new with a 60 amp junction box is this normal/acceptable.

If the "added" junction box is accessible for maintenance purposes, I see no problem with what he's done.

I've done just this myself in the past when integrating seperate DB's into 1 new unit.

What does the EIC say?

Thanks Murdock for your answer it is easily accessible and looks a good job although no mention of it on the cert.
The main reason I asked was because a friend had the same but his electrician put a two way consumer unit where my junction box is.

On the face of it, that would be acceptable, it's rated high enough and like you say its accessible.

Why would you put a 2 way board in to extend a shower circuit? That seems VERY odd

My thoughts exactly. Possibly not extended, but 2 way unit there and fed from new (another) consumer unit or direct from meter position via Henley blocks .

It is exactly the same situation as mine:- The new consumer unit was placed approx. 2m from the original meaning either the whole shower supply to the switch was replaced or a junction box etc added and 2m of 6mm twin and earth from existing position to new.
At my friends this has been done by adding a 'H-Pack' 63amp isolator with a 40amp MCB, he has also run a length of 6mm earth wire from the main consumer unit to the 'shower' consumer unit.

I can see that this would be more expensive than a junction box but I just assumed it would be more safer, a bit belt and braces.

Anyhow thanks guys I am now more happy with the junction box set up that it is safe.
