I work in live events and the 15 amp splitters are still known as grelcos. I'm in the process of changing something like 500 15 amp ends to 16, and even the 16 amp splitters are still referred to as "grelcos" by some people.

Smile Re: Another unusual plug and some other questions

Hi,
I found this item t'other day. It's an adapter to allow a European two pin plug to be used in a South African 16amp socket (the former BS546 15amp UK socket). It's nearly new and I was surprised to see that it was made by Crabtree, and that it also carried a South African approval mark. I didn't realise that Crabtree still made plugs, haven't seen one for years!
Cheers, Pete

The construction looks a bit poor for Crabtree.

Are those L&N pins hollow?

Smile Re: Another unusual plug and some other questions

Hi,
The adapter is rated at 10amps and is SABS approved. The L&N pins are hollow, being made from brass tube. Crabtree are a big concern in South Africa these days judging by their website & product ranges. Not sure how big they are in the UK though. The construction of the adapter looks a bit 'plasticky' to me as well but the Euro two pin plug is a good firm fit.
I had to smile at the idea of a Brit (me) buying a South African fitting from a Dutch couple in France. Cosmopolitan, or what?
Cheers, Pete

One has to ask why on earth there isn't a brass earth pin and side earth contacts in the socket end.

As it is it is dangerous as it looks as if it will take a schuko plug but not earth it. Shame on Crabtree.

Not just Crabtree I suspect. We gave up at work trying to find a replacement multicountry travel adaptor that carried the earth through properly when the one we had been supplying went obsolete. Luckily it wasn't critical for the application.

Smile Re: Another unusual plug and some other questions

Hi,
It won't accept a Schuko plug as the plastic projections at the top & bottom are too narrow to allow the plug to enter (I've tried!) I imagine there's an earthed version for a few rand more.
We have an adapter here in France that allows unearthed 16amp plugs (on power drills, vacuum cleaners, etc.) to be used in 6amp two pin sockets. They too have the plastic detents, but some folk cut them out to allow Schuko plugs to fit. Now that IS dangerous!
Cheers, Pete

Crabtree certainly still exist in the UK market too, though whether they're just a "name" owned by someone else, I don't know. For example:

In the UK, the Crabtree, Wylex and Volex brands are now all part of a holding company called "Electrium" which is in turn owned by the Siemens group.

USA type outlets, but sold in the UK and designed to fit UK mounting boxes are made by Crabtree.

Although intended to take USA plugs, these outlets are very different in design to those normally installed in America.
The Crabtree twin outlets have only one set of terminals, it clearly being intended that the cables would be looped via these terminals onto the next outlet just as with a twin 13 amp socket.
In the USA this is prohibited "one wire in one terminal" and outlets invariably have two sets of terminals to allow through wiring.

Must be a limited market for these Crabtree outlets since they are not allowed in the USA nor likely to be used in the UK. Possibly used in the Middle East ?

A hotel I stayed in near Gatwick Airport last year had UK, Schuko and US mains sockets in the room.

This sounds sensible and logical until you think of wiring regulations. I would guess that these had to be all on their own circuits to meet the UK regulations. It sounds expensive.

You could connect the Schukos on fused spur fittings.

I assume the US sockets get a volttage reducing transformer?

Still expensive!

USA mains plugs have become an unofficial standard in the UK for 12 volt circuits in off grid homes.

The convention seems to be
12 volt DC=USA type mains plugs
24 volts DC= old type UK round pin plugs, 5 amp or 15 amp according to load.
240 volts AC but of restricted capacity= MK non standard 13 amp plugs.

When I first went to Spain on holiday in 1973 (to Palamos on the Cosa Brava), our apartment (built in the late 1960's) had the standard European-gauge 2 pin sockets (4mm pins) for 6A circuits, and a US-type 2 pin plug and socket providing a 10A circuit for the water heater in the kitchen. The supply was the normal 220V AC.

Hi,
Most UK touring caravans use the US two pin non reversible plug & socket for their 12volt DC outlets. Our 'van had one which was made by Clipsal, as were the rest of the wiring accessories.
Cheers, Pete

In the context of caravans, does anyone remember an immediately-post-WWII plug/socket used for loudspeaker-distribution systems in schools etc. that looked rather like this connector

http://www.caravanparts.co.uk/images/soct2pin138536.jpg

which is now widely used for 12V distribution in caravans/motorhomes?

Hi,
I've got a socket that sounds similar to what you describe. I'll dig it out and post a photo tomorrow.
Cheers, Pete
