Socket with slimest back connections?

[Mark Wright]

Hi, The walls have been chased out and he fitted 25mm back boxes and to be fair you can't really go any deeper but one socket on a ring is feeding a spur so three cables and yes you can fit it in but really id like a bit more room.

Are there any sockets that have very thin connections on the back?
Thanks

Mobile phone forums etc etc . Something about many of them not having much of a safety regulator etc built into them .many people saying use a plug in charger is far safer for the protection of the item been charged etc ??

You are much more likely to have issues with cheap/counterfeit plug-in chargers than decent quality USB sockets.

I think, as with everything, if a low quality one is used then there may be problems. But the same is true of plug in chargers too.

Not going too off topic but technically now you mention it an unfused supply off a ring? maybe theres a reg being broken there.

What do you mean? Where is there an unfused supply from a ring?

it does seem a bit dodgy - the transformer malfunctions fine the MCB trips but on a ring there is also a broken leg and 32A MCB = fry time.

Anyway thanks guys for your help. Not been on here for ages. Nice to see some regular faces who always have the best advice

It wouldn't break the ring leg if the USB Socket fails though.

No I mean theres two faults, malfunction transformer and broken leg.

One of the reasons we use fused plugs in the UK is because we use rings.

Ah I'm with you.

The USB sockets will have circuit protection built in if they are built to the appropriate standard.

If the power supply for the USB outlets fails then the protection built in to that unit will operate.

A broken ring won't change how an MCB responds to a fault, it only affects overload situations.

Possibly but on a ring it probably should be fused.

How do you know they aren't suitably protected? Have you opened them up to have a look?

These units are built to an appropriate product standard and designed specifically to be installed in UK installations.

Anything plugged into a Ring should be fused in case of a broken leg. With a broken leg it becomes a radial wired in 2.5 and a 32A MCB will not provide adequate protection.

No, see my previous comment. The socket will have built in protection, otherwise it would not meet the BS standards.

Edit, not sure I understand your point. I was answering your previous point about USB sockets not being fused.

No, that's not why plugs have fuses in them.

The fuse in the plug is there to protect the flexible cable downstream of it.

The plug fuse does nothing to help in a broken ring circuit.

There not fused though are they?

"Previously, each mains socket had its own connection to the fuse board. To save copper, Britain adopted the ring main system, with sockets connected sequentially, but this meant each connection needed its own fuse. Instead of putting the fuses in the sockets, they were included in the plugs themselves."

Fused plugs are only required in the UK where we use Rings.

the flex is protected by the Fuse/MCB at the DB on a radial.
