Sparky help needed please

[lavenders19]

I have a mk sentry split load consumer unit. I had a spur running off a 32A MCB on the non-rcd side to the kitchen using 6mm wiring to a cooker inlet. The outlet was another spur to a double socket. Everything was working fine until today when i decided to get rid of the cooker inlet and replaced the 6mm wiring with 2.5mm wiring to a double socket, a boiler switch to the left and a double socket to the right.

When i reconnected everything the rcd switch tripped, even though the MCB was on the non-rcd side and the socket didn't work. I disconnected the other 2 so only had 1 spur running from the CU but still it didn't work and kept tripping the RCd on the other side of the CU. I tested the live at the socket and it was present but nothing worked.

I then decided to go back to the old way and connected the 6mm wiring exactly as before to the CU and the cooker socket but had the same problem with it flicking the RCD switch and nothing working?

Does anyone have any comments as to how I can get my kitchen electrics working again.

Many thanks in advance. Any comments greatly welcomed.

You've connected the neutral of a non-RCD circuit to the RCD-protected neutral bar?

Is it cooker switch like

cooker control unit like a cooker connection unit like (on the back there are three large terminals)?

Sounds like the "cooker inlet" was one of the first two above, with a socket at relatively low level, where the third thing above would usually go.

This being one of the first two above presumably? What was it replaced with?

Does this wiring run back to the consumer unit, or is it just from where the switch/control unit was to the socket position?

How and where are these wired?

I'm glad to hear it, though that was probably only luck. Someone has suggested a likely cause.

What inspection and testing did you do before re-energising the circuit?

Given that you have installed, "a double socket, a boiler switch to the left and a double socket to the right", why are there three spurs to the consumer unit?

I'm reluctant to suggest how you can rectify this, as the problem has not been described adequately yet.

My first thoughts, but the whole lot sounds a right old lash up tbh and wants checking over by someone competent I think.

i did not know there was an RCD and a non-rcd proteted neutral bar. I will have a look at the neutral and report back.

Many thanks
