Identifying the cables (circuits) on the CU.

[Goody]

Hi, what would you guys use to identify the cable to pair them with the circuits on the CU? Could sticky colour tapes be used? Thanks.

best using numerical cable markers such as made by critchley.

In a domestic CU I would not really be identifying conductors but if you really want to then Reg 514.5 and the use of letters or numbers, but not bits of sticky tape.

If you're just talking domestic it's normally fairly easy to work out. You'll typically have two or three sets of pairs for RFCs. The others cooker/shower (fairly obv due to size). Lighting/smokes again easy to work out. Immersion left over.

If you use coloured tape then don't leave them in the CU (just my opinion, others may disagree).

If you are doing a rewire then it's common practice to identify cables by knicking the outer sheath of cable with a number of notches where there may be some ambiguity involved. These are easily removed when finally terminating the cables.

On Industrial CU's we use Hellermann Tyson Cable markers. Tape or the ones you write on will last about 2 months before they fall off or the ident becomes illegible.

Thanks a lot for all the replies!

I've starting using the clip on markers from HallermannTyton WIC2-. - WIC - HellermannTyton United Kingdom - Products - Bit fiddly with the smaller ones on 1.0 and 1.5mm2 cable, but better than tape.

If you have loads of dosh then 3M and Gelwiremarkers Lts do something called the Trasp system, with slip on and clip on carries for your labels - Trasp

Do these stay on 1mm and 1.5mm cables ok?

I got two packs - red (0.5-1.5) for the 1.5mm and blue(1.5-2.5) for the 2.5mm - this one too loose for the smaller dia cable. Haven't tried on 1.0mm yet.

I think they look neater - and can be re-used. Fair warning - you will drop a few of the little blighters!

 

[Amp David]

where did you get them from?

 

[sparc]

Farnell - unfortunately - as it's a lousy site to shop on.

HELLERMANN TYTON|WIC1-0-9-PA-CC-T1|MARKER, CLIP-ON, SIZE1, VAR, PK200 | Farnell United Kingdom

The downside of getting all the numbers like this is you use a lot of '1's, but not that many '9's - still there's a couple of hundreds so it should last for several CU installs.

these are ok untill you have a few disconnected then they tend to slip off if its just for marking during a CU change then Scotch 3 m reel of sticky there are cheaper options BUT they dont stick as well
