Melted socket

[Jhcp1977]

Hi can simeone give me advice I had a electricia install a outside socket that has melted the plug before I ring him can someone tell me if it's been installed correctly? I can't find the makes anywhere online are they inferior products?
I am not happy as my daughter was in the hot tub at the time so shouldn't have something tripped in the house or the RCD on the lazyspa ? As with it all being melted it was still working it's only because she could smell burning I was alerted to it ?
So from what I can see the middle switch is what it's connected to with a single cable running to a outside weatherproof socket any help appreciated

Will do when I get home

Yeah going to but my concern is nothing tripped should it have ?

That looks like overheating of the plug, normally the fuse would go if it was all to specification and really overloaded, but often poorer plugs are not able to really do 13A for long periods.

What is the hot tub specification? I.e. is it designed for use with a 13A supply plug & socket.

Does this help ?

that load should be no problem for a 13A plug. as previous posts, I'd say original cause in plug at the fuse. either way, you need a new outside socket.

Yep got the electrician coming next week can you tell me was she in any danger in the hottub while this was going on as I am in 2 minds to bin it if she was incase it happens again

Strange specification, Heating: 2050W, Heating + Bubbles: 1850W I suppose it could cut off one of the heating elements to start the bubble pump, but a bit odd.

I'm wondering if that specification is correct, Heating + Bubbles could be 3900W which would explain the burning plug, but not why the fuse did not blow?

 

[telectrix]

no danger in the tub per se. . the only danger would be the outside socket getting hotter and damaging the cable/s feeding it, and any close combustible materials catching fire. get the sparks to fit you a good quality plug while he's there.

 

[Jhcp1977]

Why was it open all night? that type of outside socket has a lid that can be closed once the appliance has been plugged in, did you in fact do that or was the socket left exposed whilst the spar was in use? The socket could have been splashed with water from the spar, which contain chemicals and compromised the plug.

No it was left open as I just forgot to close it after switching electric off in the house and unplugging it

I know that both will not work the same time

Thank you all speaking to a different electrician I explained that's there's a single 2.5 twin and earth run straight from a outside socket to a 32amp MCB and he said that's not right any way I will wait and see but what's your opinions on that correct or not

Don’t these come with moulded plug and an inline 10mA rcd?

I’m saying, has the original plug (and possibly the rcd) been cut off to shorten it perhaps?

Yes, that plug does not look as it has bee professionally fitted judging by the neutral conductor.

 

[Mike Johnson]

Difficult to tell from the picture, but as you say the neutral conductor does look as though it could have been pinched by the top fixing screw as well.

Not sure but this is on it

that's a 10mA RCD factory fitted in the tun lead.
as for the 2.5mm cable from a 32A MCB, is that cable direct from the MCB or is it a spur off a socket in the house? if it's spurred off a socket on a ring final, as long as it's the only socket on the spur, it's compliant.
