1st Fix / Cabling / Wiring Standards

Recommended Posts

On a recent project our Engineers were pulled up for a few issues regarding their cabling:

 

1. With cable laid in underfloor voids, they didn't use the data matts that were provided

 

2. They didn't clip their cables to the slab

 

3. They ran cabling over ductwork, not underneath it.

 

 

To be fair, it was work done by our 1st fix sub-contractors, rather than our Engineers. However it is actually up to our Team to show the subbies the standards and check that everyone installs to this standard.

 

We are going to put a 1st fix guide together with pictures to show our Teams in future what we expect.

 

Silly question (as i'm not an Engineer), but where do I go to find out about best practice and regulations around running cables for security systems?

 

Thanks.

Over ducta seems better incase duct needs to come down

All your cabling comes under BS7671 unless it has its own standards like London under ground and the likes.
