18th edition final changes released by IET

[Midwest]

Generally cables installed above a plaster board ceiling with a minimum 30 minutes fire protection will not require metallic fixings.
If it where the case we would need to be doing now on our works such as new builds where cables are installed above a ceiling to landing areas and halls just above your front doorway.

I recall watching one of those IET videos from an Elex show, where that Darren Staniforth (NIC/Elecsa) was ridiculing a colleague from Napit, as Napit interpretation of the above, is that plasterboard ceiling would not meet the proposed new reg change.

Interesting how people interpret things differently, isn't it!

My Mrs Miggins, is not going to be happy me taking her ceiling down or most of her floor, to clip a cable with suitable fixings.

What's also interesting, is members seem to know how the new reg changes will be construed, even before the 18th is published.

Metallic pipes entering the building having an insulating section at their point of entry need not be connected to the protective equipotential bonding (Regulation 411.3.1.2).

Has anyone actually seen such an install?

PS not having a dig at you Spoon!

My water pipe is like this.

In regards to the bonding, if it tests out as an extraneous conductive part then bond it, if not then no need!

Why do the iet need to write some new stupid fandangled regulation to decide if Bonding is required. Just test as normal and apply protective binding if required.

What metal, piece of plastic threw wall, then metal? Surely plumbers don't do that to save us from the effort of bonding?

Mines plastic then all metal, seen all metal and all plastic, but none with a teeny piece of plastic?

What do you do, if you test it on a new build and find its extraneous, and you haven't dragged in a cable?

My pipe comes up through a concrete section in the kitchen, (about 2 foot square section) and that is plastic. All kitchen appliances are plastic pipes. Change to copper pipe when the pipe goes boiler.

Pull one in I guess. At the end of the day the installation won’t comply with regards to fault protection if it is missing where required.

Arrrgh, I had visions of a metal service going up an outside wall, changing into plastic through the wall, and then back into metal on the inside of the house
