Earth straps

[alan blackburn]

My bro in law fitted a new bathroom suite for us cheap, very good. He also disconnected the earth strap from the mains electrical circuit to the pipework behind the wash basin, but did not refit it.

How would I go about refitting the earth strap please, where do I connect it to in the electrical circuit?

Same question for the kitchen too, he also fitted that!

You need to read, learn and understand all of the requirements relating to this:

Bathrooms: http://www.niceic.org.uk/downloads/NL139supp.pdf

Extraneous definitions: http://www.niceic.org.uk/downloads/E169-9.pdf

Earthing v bonding: http://www.niceic.org.uk/downloads/Earthing Bonding guide.pdf

Earthing plastic pipes: IEE article on plastic pipes.

You should also, in case you care about the legality of what you do, be aware that work on supplementary bonding in bathrooms is notifiable.

Same question for the kitchen too, he also fitted that!

There are no requirements for supplementary equipotential bonding in kitchens, but if the kitchen is where the water/gas/oil supply pipes enter the house then there should be main bonding cables between those and the main earth terminal. The size of bonding cables that you require depends on the type of supply that you have, and possibly on DNO specific requirements, and given the questions you're asking I would advise getting an electrician to sort out the main bonding.

And to sort out your brother-in-law if he disconnected those....

That is really helpful thank you, the half pint and a curry doesnt seem very good value!

Just reading the part p amendments which afaik come into force on 6th April, if I am reading them correctly installing or upgrading main or supp. bonding is no longer notifiable.

With all the new H&S, Building, Company, Employer, Employee, CCTV, Data protection regs (to name only a few) that have been introduced in the last few years I'm wondering just how much reading we are expected to do to stay on the "right side"

Anyone fancy a discussion on the implications of banning all steps ladders on site, the scraping of the CIS 715 card...and so on

Well it would certainly statistically stand to potentially save more lives than part P has, but I expect the goverment is well aware that nothing would ever get done if they introduced that bit of red tape.

Of course some people would take to inprovising if a ladder wasn't available, back when I was doing my A-levels at college I was part of the team that helped out with the technical bits of any theatrical productions they put on, we had borrowed some PAR cans and rigged them on the bars above the stage, maybe 10-12 feet above the stage, the tower was taken apart before they got derigged, and I remember a mate of mine standing on top of a stack of theatrical tables/platforms, with a chair on top trying to de-rig them

Did you learn that while on holiday in spain? Sounds safer than their scaffolding
