flex thickness

[Deansplit]

Is 0.5mm 3 flex ok for a 60w pendant? I always thought 0.75 was the norm?

 

[PrenticeBoyofDerry]

0.5mm flex will carry 3A max
0.75mm flex will carry 6A

 

[Deansplit]

thanks, so what's a 60w bulb?

 

[elrobbo82]

roughly 0.3A on a 230V system

 

[Deansplit]

oh, so 0.5 ample for normal light bulb or low energy then?

 

[securespark]

Yeah, if you can find 0.5 HR flex.

This is listed on TLC's website: http://www.tlc-direct.co.uk/Products/CA0dot75HR2.html

They do 0.5 HR, but it's multicore.

 

[Deansplit]

well I've already found one - it's not HR, what's that?

 

[OwainDIYer]

what's the weight of the pendant?

 

[Deansplit]

oh it's only a 25sm aluminium sphere so dead light, I just liked the flex so driven by the fact it's 0.5 - it's this one

that would be fine for what you need it for. just ensure you tape the braiding so that no strands can touch any of the terminals. some people will say that you will have to earth the braiding some will say you don't. i have recently passed my AM2 where they did not want the braiding earthed and was told that the braiding wasn't designed for this use.

probably get shot down for this but as i said just qualified and eager to learn!!!

I would use clear heat-shrink rather than tape.

weight of pendant is not a problem unless you are going to place an extremely heavy shade on it.

More specifically, the regs. specify up to 2kg on 0.5 sq. mm and up to 3kg on 0.75 sq. mm.

tape would do the job fine as all your doing is ensuring that no strands are able to make contact with the other terminals. you wont see it as it would be hidden by the ceiling rose.

In other words it is insulation.

Tape does not comply.

 

[elrobbo82]

ok, ok it doesn't comply so heat shrink would be the right choice but personally if it were my house i would twist the braids together and terminate into the earth terminal using earth sleeving as this braiding could be considered an exposed conductive part. even though on my AM2 exam they stated not to.

since the op is doing this work on his own property does he have to comply and would it be considered unsafe?
