Flex in a consumer unit

[Dec1977]

Hello there, Is there any regulation regarding the use of flex in consumer units. eg. Can a 1.5 x 3core be used as a supply cable from an 6a mcb to a fused spur feeding downlights? I came across this the day and I was curious if it was within the regs. Thanks for your time.

Flex is It's permanently from FSU ,obviously and is perfectly fine and acceptable . So yes it's not good practice and I'm not condoning it just it will do the job ! . excuse me I thought that would have been a given

To be honest with you, i can't make out what you're trying to say here??

It would never have occured to me to use flex for fixed wiring, but I'd be interested to hear why its classed as rough. I'm assuming its because its stranded so more prone to damage, strands breaking etc and affecting CCC?

i don't really understand why it would be a bad thing , if it were up to me i would wire a whole house in flex think how much easier and quicker it would be

Use of flexible cables
521.9.1
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.
NOTEescriptions of light, normal and heavy duty types are given in BS 7540.

is it just me or do the regs not make much sense most of the time

It is not just you, they are written in a different language lol, as is C&G exam questions

For me it's a pride thing, use flex for fixed wiring in a domestic application, come on

Nee botha then.

I did quote a reg number on a previous thread about Flex actually, It started to get heated LOL, Basically it is allowed but like E54 and many others here think it is the wrong cable for installs and it should only be used from a spur to an appliance.

I wonder how factories wired in SY, CY and YY haven't burnt to the ground yet....

Must be just luck. The next time I do a job at a factory with multiple drives, valves and instrumentation I'm going to wire it all in twin and skin just to be sure.
