Teardown of a new MK screwless socket
Added 2021-09-27 04:23:15 +0000 UTCFor a moment I thought they'd used brass plated aluminium for the earth busbar, but it appears to be solid brass plated with a silver-like material. I say silver-like, because silver has become very expensive due to "investors".

It'll be interesting to see how these new sockets fare over time. If it's successful it will make for much easier and potentially better contact termination.

They have to invest in useful materials. Creating an artificial shortage of useless materials doesn't work, as there are no locked-in buyers, and the price doesn't rise far. Capitalism. Who needs it ?

2021-10-21 16:29:16 +0000 UTCa plating on just one side could be both steel screw thru rivet and possibly corrosion resitance from moisture ingress thru front plate holes ?
2021-09-29 10:31:59 +0000 UTCIt's an interesting design. In Canada we're still in the dark ages with wrap-wire-around-screw-and-tighten being the standard socket and switch connections. I'm guessing that plating is zinc, but I have no idea why you would plate brass with it - particularly only on one side.

2021-09-28 03:50:02 +0000 UTCJohn Ward tested some Wago connectors that use a similar system to destruction, and they took a high current for a long time. But time will tell with these. When working with Hussmann I across the original Wago control panel terminals in outdoor condenser systems, and asked the service department about them. They said they had no issues with them. The Wago terminals have routinely been used in commercial wiring in Europe for a long time.

2021-09-27 17:12:32 +0000 UTCMy main worry on any sprung contact is temporary overheating leading to loss of spring and thermal runaway. Maybe you looked at that previously, Clive? Will probably show my ignorance here but a 32A Type B MCB needs 70A to trip in 100 seconds. If you're near the end of the ring, all that could be going through one contact.

2021-09-27 14:26:18 +0000 UTCI would venture to say no.

2021-09-27 08:26:40 +0000 UTCDo they make ones for the USA?
2021-09-27 07:58:15 +0000 UTCYou beat me to it. ๐
2021-09-27 06:35:13 +0000 UTCIt's probably zinc plated?
