Page 5 of the BBB will be a good starting place..

No, I'm not a fireman.

Watch the videos by John Ward and SparkyNinja who explain all the changes in the 18th edition.

Never experienced fallen cables that hindered me in a house fire, nor the melting of plastic rawl plugs causing items to fall.

30ma RCD for lights irrespective of install method

SPD’s except where the total value of the installation and equipment therein doesn’t justify such protection.

Clear as mud

There seems to be an inference that 521.10.202 does not apply to domestic installations. This is not the case.

521.10.202 is a very significant change which will require consideration to achieve compliance. I predict there will be an awful lot of non-compliant new builds and extensions during 2019, because many will just carry on as they always have.

Hum ......... so in a finished domestic premises how would anyone know or check this?

Serious question BTW

Little is done now to check any existing BS 7671 compliance - so why focus in on this?

being a tight fist, i not got 18th book.can you paste that reg?

 

[Ian1981]

There’s not many instances where a new build would be effected by this other than if trunking is used to house the cables to the DB or any detached garages with surface conduit drops for accessories inside.

Are you suggesting you will ignore this regulation?

521.10.202
Wiring systems shall be supported such that they will not be liable to premature collapse in the event of a fire.
This is a blanket requirement, no distinction is given to areas of wiring or type of installation. I have been informed that a plasterboard ceiling is not considered to provide support for cables in the event of a fire, and that all wiring throughout its length will require support with (for example) steel straps, unless it is drawn through joist holes.
This will have implications for rewires where cables are often fished through areas where floors are difficult or impractical to lift for access.
