Wylex twin screws

I see there are doing twin screws now. Wonder if it was the DNO's request.
Who knows - but it doesn't surprise me. One the the good features of their wonderfully-engineered Standard Range of CUs was 'twin screws' for almost everything.
Also did they ever do an enclosure to suit these ?
Yes, but IIRC it was more of a 'cover' than an enclosure such as we would now use. The device screwed to the backboard and then the (backless) 'cover' screwed to the device. I think I've got one somewhere - if so, I'll take a photo!

Kind Regards, John
 
It's a great idea - originally used on their rewireable boards in bygone years. I think it is wise of them, and maybe other consumer board makers, to re-introduce twin clamping terminal screws once more. (M2 boards already do).

I can't see how tunnel clamps would work with more than one screw, but I do think that a hole in a piece of brass with two screws directly on to the conductor provides a better connection.
 
I'll second that.

The old MK DP switches had dual screws and some new accessories do too, like Click's 50A DP pullcord switch.

I agree.

As you say, I don't think that a tunnel clamp with more than one screw would really work - or, at least, achieve anything. However, one could presumably have a 'split' tunnel clamp - i.e. effectively two tunnel clamps, each with their own screw, separately and independently gripping the conductor.

It gets a bit more complicated if there is more than one conductor - but both approaches have issues in that situation.

Kind Regards, John.

That does look very similar to the terminals on proper henley blocks (and I don't mean any old service block btw)
