Convenience Store Lighting Rewire

[IAmSparkytus!]

Any issues with wiring lighting in 4core flex rather than 3core and earth?

Approximately 50 LED panels to wire all fitting into a suspended ceiling.

I know some lighting design/manufacturing companies sell plug and play style fittings and wiring which I think may be H05.

Is there a great deal of different in the properties of standard rubber flex (not sure of the correct cable ref for this) and H05?

Can both be used or stick to H07?

Wouldn't say it was customer-led. The customer was given acceptable options and decided for themselves what they could afford. I don't see an issue with that.

Whats the health and safety aspect of the proposed work which concerns you?

It is not health and safety of the proposed work but of future maintainence and fault finding work.

Being able to unplug a light fitting and take it down to work on it or replace it reduces your working at height risks.

529.9.1
A flexible cable shall be used for fixed wiring only where the relevant provisions of the Regulations are met. Flexible cables used for fixed wiring shall be of the heavy duty type unless the risk of damage during installation and service, due to impact or other mechanical stresses, is low or has been minimized or protection against mechanical damage is provided.

NOTE:
Descriptions of light, ordinary and heavy duty types are given in BS EN 50565-1.

I'd have thought for this the risk of damage would be low, so perhaps heavy duty not necessary, IMO.

Very unlikely imo flex hooned in a ceiling void will be subject to much mechanical stress

Everyone's had 2p put in their box tonight it seems!

Metal fixing band above the ceiling as containment. Again, cost cutting. Usually fit basket tray but this is £10-£15 per length as opposed to a £5 roll of hole-band!

Look, I get it, sometimes the customer can’t afford the AAA* job you would like to do.

however we have to be careful not to lower the standard so far that it gets close to not compliant installation.

note, it is so frustrating when you put klick sockets in all the right places and then the ceiling grid goes up and the fitters turn the space above into an imitation of a snake pit with lighting and data cables everywhere.

Equally frustrating when you put them in all the right places, but later find youself fitting out rooms in which someone paid no heed to drawings.
