Main switch AND isolartor in consumer unit

[gvelec]

Hi all, any ideas as to why this installation has an isolator next to the main switch? To my inexperienced eyes, this seems unecessary waste of real estate.

Photo doesn't work mate.

If it's as you say, pocket one. I can't see it either.

Is this domestic? The isolator pre consumer unit could be for isloating the consumer unit to work in or change without removing the main fuse.

I read it as it's in the CU. We'll never know unless the OP gets back to us.

Sorry. User stupidity! Domestic board. Hope it works this time. I can preview it fine!

Oh dear, wonder if that was once a dual rcd board.

Here's a close up. I need to free up space on this Wylex at some point for a couple of new circuits, so am doing 'preliminary enquiries' :icon10:

Looks as if a emergency repair at some point and the spark only had a main switch to temp it, temporarily forever lol

Or a rcd fault they couldn't find.....

Look at op other thread about finding fixing screws live in sockets

 

[keniff]

So this was replaced because the rcd kept tripping I reckon

 

[telectrix]

that's how i see it. rcd tripping. so called spark can't fathom out why, so bungs in a main switch. easy fix .

I too think that it was once a dual RCD board and either due to a faulty RCD or a fault that couldn't be found the "spark" has replace it with a main switch. I would test the circuits then fit an RCD back into the board

Seems to be the case which explains my other problem on my other thread where I'm having an earth fault. If there was an RCD in place on the board, the sockets in my kitchen (next to isolator on board) would keep on tripping.
