To Crimp or not to Crimp???

[davesparks]

Hi.

I'm just starting out on my own and really appreciate the advice given here.

I'm installing my C/U (eventually to be used for my NICEIC assessment) and I need to extend all cables 30cms max. I've done lots or research and decided to crimp them and locate within an adaptable box.

I don't want to get the wrong type of ratchet tool and butt crimps. Are the following acceptable for 1.5mm2 upto 6mm2 (different coloured sleeves aside)?

Also, is this the best approach? Reluctant to use din rails because of cost but will if it's the best way.

Many thanks, Rob.

That doesn't look like the right tool for insulated crimps, especially considering it has positions for and is marked up for cable sizes up to 10mm whereas a crimper for insulated crimps would normally just have the three positions for the three sizes of crimp.

Of course it doesnt need to be metal, it doesnt house any switchgear. @shinypen you may gind when you come to do cu change that there is a bit of slack on the cables underfloor so you may not need to extend

Seems your advice hit home.amazing what experience can be imparted to the un initiated

the 6mm cpc was redressed after the photo was taken as it looked rough.

cable entry was sealed with a bit of mastis. as was the hole in the ceiling, when testing was complete. . well spotted, though.

any decent wholesaler will stock the din rail connectors. you can get screw terminals or wago style push-ins. the box is just a bog standard adaptable box. or try here:

din rail terminals | eBay - http://www.ebay.co.uk/sch/i.html?_from=R40&_trksid=p2047675.m570.l1313.TR3.TRC1.A0.H0.Xdin+rail+terminals.TRS0&_nkw=din+rail+terminals&_sacat=0

I would suggest the best quality Din rail Connector.

If an odd cable or two is too short, you could also consider rewiring/replacing the short cable

Those pre insulated crimps are designed to be used with stranded conductors, not solid like t&e
