Help needed, is this correct?

[ASH77]

I have a two 32mcb in the c/u. I thought one would be for the upstairs sockets and one would be for the downstairs sockets but they are not.

both require switching off to cut off power off to both upstairs and downstairs sockets!! is something wrong with this?

each 32mcb has only one live exiting, surely you cant have a ring circuit from one mcb to another, it should exit and return to the same mcb, shouldn't it?

Unfortunately this is quite common. Suggest you get a spark into check and resolve

So i guess its dangerous?

Could be they’ve split it front to back....had that a few times on old terraced houses...

Edit....sorry just read the post properly ignore me

Have you carried out any dead testing on the two circuits in question r1, r2 or rn? What size cables are the CBs feeding?

 

[ASH77]

Hi Pete, Im not an electrician, I wish I had your know how. The cables are 2.5 t&e, black and red.

I did an EICR on a large house last year .......... all the 32A breakers had 2 cores ............ unfortunately, none of them were paired correctly

get an electrician in to see what is going on, from first appearances, this is both wrong and under overload conditions could be potentially dangerous.

Sometimes you will get legs going to feed upstairs then en route they drop down in a chase to downstairs sockets.
Best way is with a plug in tester, switch one MCB off and mark which sockets are off with that one, then do the same with the other.
Mark it on the socket or on an A4 sheet and stick it with the consumer unit.
It’s the way it is sometimes.

Was going to a second time but hit the back button instead - foot of stairs!
I’d be right in a parallel universe though!

I had the same problem in a house on my street. Needed 2 MCBs turned off to isolate any sockets.
Legs of the rfc’s Mixed up in the board.
Note: it’s not a diy fix. You need the proper testers to identify what should be where

We see this quite a lot on the houses that we test, also see supply and load mixed up at fused spurs. Switch the spur off and the ring is broken.
