I am doing a garage conversion and bought and installed an MK RCD consumer unit, 8 way.
Is there best practice for the layout of the different circuit connections on the CU.
Going from the left of the CU I connected it as follows:
first there is the main swithc then lights circuits (3) and one spare MCB
RCD unit, main house ring, kitchen ring, cooker spur, and one spare.
So the wires to the left of the RCD are non RCD connected whereas those to the right of the RCD are RCD connected.
Is this the best way or are there conventions ?
Also. should the incoming wires be clamped using cable clips to secure the wires prior to termination.
Some wires come up from the ground, 5 foot then loop though a hole in the chipboard backing before terminating in the CU, others come down from the ceiling and go throught the hole in the chipboard then are terminated.
None of them have clamping or cable clips on the chipboard, and whilst loose are unlikely to be stressed at the termination points.
The bends in the wires going through the chipboard backing support the wires I reckon.
And finally in the bathroom the only electrical point is a shaver socket, no electric shower nor electrical heater, so does the steel bath and copper pipes need earth bonding?
As this CU will be checked by a sparks before hooking up to the mains I'd appreciate any advice
