Cracking answers and shows that people do have a healthy respect for the mains electricity supply for the most part.

in fact if you really want to be scared about mains electric ......

it is ac ... alternating current ..... ie ..... its 240 v ( rms ) positive , but also 240v ( rms ) negative voltage too , so you actually have a potential difference of 480v ( rms ) , the real potential difference is much more

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
However I think the 17th edition regs allow non bonding if the right consumer unit is fitted
I just plug it in and let sparky work out how to get the certificate

Why is this
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.
