Fly leads...or not?

[Spudnik]

Just to add fuel to the fire, accessories should not be removed while they are still live.

This (IMHO) negates the need for flyleads.

It's stated in IEE Guidance Note 1.

does that mean its in bs7671 then? arent the guidance notes books just that, guidance on interpreting the regs book. ie whatever is in the gn books is referring to specific regs all but written in plainer english.

im not having a go ristead i'd just love to know where this statement comes from as i've used it myself in the past be it a screw missing in a back box or whatever. just nice to have a bit of a back up in black and white. what regs it relating to and what does it say exactly. give us a quote if you can find it '' i've got gn3 not gn1 unfortunately.

cheers

I always fix fly leads- its a better job. however, on a recent rewire, i find the metal back boxes are have no connection point to them, .e. the little bras connectors in the corner. On the phone to the niceic help line, and as long as the boxes have a metal screw to the metal back box, then they dont ned to be installed, because the metal screw from the fce plate makes the connection from the cable earthing, to the metal back box. So this saved me 30 odd cutting out and re instaling back boxes (or self tapping screws and crimping etc.) however, thisncouldresult in the screw on the face plate becoming live, in the event of a fault on a susceptible system. quality prevails, and all thse back boxes now have fly leads. Quality work, sleep at night, reputation.three days late for next job.

if you wouldn't mind guys - a photo showing how these fly leads are applied would be appreciated

 

[rocker]

... can't do you a photo but basicaly they are the earth wire that connects to the little brass connection block in a steel knock-out box to the earth terminal on the accessory

 

[pennywise]

it's only a bit of 1.5mm green and yellow singles attached to the the earth tag on the box then to the face plate terminal or a bit of T+E bare cpc sleeved.

does that mean its in bs7671 then?

No.

But the IEE's opinion is certainly worthwhile. Only the Regulations are in the Regulations. Guidance Notes don't form part of them.

Will write it up later for you but it's not specifically in any Regulation other than that they should be earthed, but of course they already are reliably earthed with fixed lug.

Does it have to be 1.5mm?
Lots of jobs that I have second fixed the main contractor has given me a 50m drum of 0.75mm for the fly lead on ring mains , presumably for cost etc

 

[rodney12]

Can't see anything wrong with using 0.75mm for the fly lead, end of the day it's not a requirement to add a fly lead at all really.

 

[spenny]

same as everyone else , good practice , not regulation
