MK LOGIC RAPID FIX

AJJewsbury

Anyone tried the new MK sockets with lever terminals?

Obvious failing to my eyes is only 3 PE terminals - if you're spurring off from a ring and prefer to have a fly-lead to the back box then you're going to need 4. (OK you could loop one of the c.p.c.s through the back box terminal if you're using reduced size c.p.c.s. (e.g. T&E) - but it's a bit messy and probably isn't going to work with full sized c.p.c.s. as most many back box terminals won't take more than one larger conductor).

    The Earth colour is not G/Y because that throws up all kinds of moulding difficulties, and means a complex second set of expensive dies and a double (2 shot) moulding machine. It doesn't matter does it and this is not cable insulation so out of scope for BS7671? I am much more concerned that wires are not tightly fixed as I said above.

    You need to study creep somewhat Graham, it is not a normal temperature phenomenon in copper, only perhaps if the wire gets very hot (hundreds of degrees), and usually work hardening will limit any small change due to the screw pressure (which is very high hopefully).
