Hi, I have an issue I cannot get my head round.

I have been asked to replace a consumer unit, and the circuits are run in steel conduit with singles for live and neutral and using the conduit as the earth for sockets and lighting. There is also an MICC cable supplying the cooker.

There are two conduit’s entering from the bottom of the CU, and one conduit from the top of the CU along with the MICC entry.

My problem is modern consumer units are taller than the old ones, and I don’t know if it is practice to cut and rethread steel conduit fixed in place and containing cables.

I would consider mounting the new consumer unit in front of the existing unit so the conduit and MICC does not need to be disturbed, but my worry is that once the new consumer unit is in place, the earthing for all circuits is only accessible by dismantling the current consumer unit.

Any Advice?

Regards
