Any tips on wiring 3x 2.5mm cpc's into a 13a socket?

[rewireIT]

Every time i go to do this, even with correctly fitting sleeving, it seems to be a right **********")£"$$* of a job getting all three in snugly without the sleeving riding up and making it difficult to tell whether i clamped on sleeving or copper.

Any tips for not fighting with this? It just took me like 10 minutes to put the cpc's away in a socket with a spur coming off it because i couldn't be 100% i'd got all three in correctly.

Their DP socket has a 2nd earth terminal.

It's the MK Logic Plus DP's that i've been using. Only one terminal for each wire

Turns out they are DP - I'd long thought K2747 was SP.

Anyway, K2746 (with outboard rockers) will have 2 earth terminals.

The only issue I have with MK accessories is that terminal entries aren't 5.5mm flat blade friendly.

I actually prefer the look of those, will probably grab some of them in future.

I think those were the ones intended for "high intergity" earthing for IT use (RFC or looped CPC with separate terminals for eacy connection so loose screw only breaks loop, not allowing anything to be CPC-free), as well as lower risk from accidentally switching off to loads by mistake. Cost a bit more though.

Generally a bit more expensive - probably because Screwfix don't buy them by the billion.

The MK sockets with Wago-style clamps look interesting, got one somewhere but not actually used it yet!

They are indeed.

Hi what do you mean by IT? Racking my brain here and can't think what you mean.

Got a couple of boxes myself and they're great at taking up shelf space.

Lol you're not using them?

Here "Information Technology" the idea being often that stuff has high leakage currents compared to common domestic loads. I think some of the rules might have been deleted with AM2

Computers and stuff.

I will eventually. Have to remember I have them at the same time as needing them - not easy.

I take it you don't do a lot of domestic then?

Bleeding hell i didn't think IT would be that IT lol. Didn't think it could be that obvious and thought there was some obscure electrical terminology i was missing out on

A bit of everything, but most domestic work is after hours.
