What adapter do i need for this plug

[darael]

fair point, I think I was meaning it could/would trip the 5A circuit

It's possible the surge current of the motor starting could trip it, as doing so might briefly draw 1kW or more.

It's a 15A round-pin.

The smaller version is often used as a connection to your lighting circuit. Things like bedroom lights and so on, where they are connected to a low amperage circuit.

I am not aware of the 15A being used in the home, it's more of an industrial lighting circuit thing. Perhaps there is a specific reason why one was added to your fuse box. Something someone needed more than 13A for. I would check the fuse on it in the fuse box and potentially downgrade it to a 13A socket and smaller fuse (breaker). It will be more use to you.

(In other words, don't buy an adapter, replace the faceplate and the breaker).

I think your right, the large round pin is 15amp the middle is 5amp (light) and the teeny one is 2amp (light) i have one of these in my living room

It's very unusual to see them in a house these days. The middle one is the most common, because it's ideal for connecting things like bedroom lights in to a switched lighting circuit. Lighting circuits are usually 6A so you can not put a 13A socket on there.
It's very rare to see the larger brother in a house. They used to be very common next to the fireplace, because they supplied a heavier current to one of those big bar heaters. As I said, though, they are still used for heavy duty lighting circuits.
I am not sure why someone would have put one on a modern fuse box. They must have had a specific application.

OP mentions this is in a communal hallway, so possibly they live in a block of flats.

It's a 5A socket for a light, a hoover (at 13A) would likely pop it.

Buy an extension lead, they are always useful and negate you farting around with a completely useless adapter

The cleaners plug the hover in to it.

The owners of the building have clearly used this type of socket to stop people using their electricity and you probably should not be trying to find a way round it

Is that link going to take me to a picture of your butt hole?

oh wow

These are still fairly common in theatres. It's used to denote sockets that are attached to a dimmer system and not directly to the mains.

I'm with 964rs

Just buy a 15A BS546 plug and and make a short extension lead upto a trailing 13A socket. https://cpc.farnell.com/pro-elec/wp15/15a-round-pin-plug/dp/PL03445 And yes, Its likely what it is to stop other folk from using it, just be glad its not one of the ones that looks like a normal socket, but has a T shaped earth pin, that confuses folk when the plug doesn't fit ( https://flameport.com/electric_museum/plugs_13A_non_standard/mk_non_standard_t_earth_pin_plugs.cs4 )
