house electrics question

[makeitfit]

Causes me no end of hassle fitting kitchens. All our plumbing is in plastic, 90% of the sinks I fit are composite, dry lined walls and plastic insert pattresses etc etc. Alkathene mains in :augie
However I think the 17th edition regs allow non bonding if the right consumer unit is fitted :nenau
I just plug it in and let sparky work out how to get the certificate :lol

rms ( root mean square ) is 70.7 % of the sum , so that needs to be taken into account when working it out ......... oops sorry jim :lol:lol:lol

Soo, what's the rms mean on a speaker, as an auto electrician I should know:doh

I'm curious to why all radiators, matal sinks etc are earthed In my house, and they aren't connected to a 240/250v supply

Why is this:nenau

its called "Earth Bonding" and connected to the eathing plate on your consumer board, if a cable in the floor wears against a copper pipe it could short out just as you are touching the sink or radiator, or even having a shower.
