Hi can anyone help me, and before anyone says yes I will have the wiring checked before switching on, but want to get as much of it correct myself before doing so.
In the utility room there is a double power point and two double poled isolating switches above a work surface all of which are part of the kitchen and utility ring main.
2.5mm2 spur cables has been run vertically below each double pole isolating switch to single socket outlets below the work surface, to plug a washing machine and tumble drier into respectively.
Below the two socket the outlets, hot and cold water pipes will be running which could be touched at the same time as pulling the plug, and yes if I operate the isolating switches the single socket outlets will be dead.
Above the work surface I can touch the taps and the electrical fittings if I try.
In days gone by even though the ring main has an earth wire in it, usually a 1.5mm2 cpc together with 2.5mm2 conductors.
A further earth wire in 2.5mm2 or 4.0mm2 if not mechanically protected would be run from the socket outlet or isolating switch and bonded onto a water pipe as an added precaution so there would not be any potential difference between the plumbing and electrical fitting under fault conditions.
Question: As any of the five fittings could be touched whilst being in contact with the plumbing would I have to daisy chain them with a 2.5mm2 where protected and then a 4.0mm2 where the cable connects onto the pipework, or is there no need these days as ring mains are protected by RCDs.
I know I could just bond anyway, as the saying goes if in doubt bond it anyway.
It’s easy enough to put the side cutters through it if not required, but could be a sod to put it in after if needed.
Many thanks to anyone who just loves to read a copy of the IEE wiring regs before going to bed at night.
