They are quite common in computer rooms where sockets are installed

floors - but there are lots).

Dunno about "quite common", though. I've been working in computer
rooms for 32 years now and I've never seen one before.


Well, I've done lots, in broadcastingplant and associated equipment -
routers, etc.

Placed under the floor, with a lid, under the equipment they serve, they're
an elegant answer.

Ours all used standard 13A plugtops, or in the years of madness, Walsall

Where do you buy the plugs or distribution boards? All the ones I've seen
have used Commando plugs.

Why madness? Apart from cost they are pretty reliable.

That's a big ask, considering how long I've been retired, but like this

The connectors were ok, it was the folks who changed plugtops or made
interconnects so vacuum cleaners, angle grinders, etc, would work on the
super quiet tech mains. And all the legit gear that had standard connectors
so had to be worked round in a Walsall area

Why *switched* sockets though? There's no real need for switches, as
people just switch off at the appliance when necessary, and there is a
risk of unwanted switching off when somebody opens the floor box for
whatever reason.

I would prefer BS 546 round-pin plugs, available from more
manufacturers and the round pins/tubes are a more reliable connection,
especially at high currents. Square-pin socket contacts are prone to
losing 'springiness' and overheating, the design was originally to save
materials after World War 2, as was ring-circuit wiring.

Ah - sorry I was sort of wondering about the non fused 13 amps plugs.
Confusion reigns...

You're confusing me again. Surely there was a 'cooking' supply in the area
too?

Well, me, I was only a planner and installer; the specifiers said that
theis was the problem and stopped specifying them.

But my earlier operational experience confirms Murphy's law in spades!
