Cooker socket tripping RCD

[Benedictus]

Hello , i have a problem here , the cooker socket trips the RCD even when its off , what could be the problem? neutral to earth fault on the socket? Please help

Is it actually a plug and socket for the cooker?

If so unplug the cooker and try your kettle in the socket

 

[Benedictus]

Thanks for you reply , the stove is wired into cooker socket , everything on the socket if off and still tripping

Can you post up a picture of the setup you have as I am a bit confused as to wether it is a socket or a cooker switch.

I am not familiar with wiring conventions in Botswana. Can you also post photos of the thing that is tripping, please.

When an RCD trips even when everything is unplugged or switched off (with a DP switch, which is common here), water ingress and/or cable damage may be suspected.

thats the setup the big red one switches on the electric stove

 

[JohnD]

The switch (cooker control unit) looks quite old, but we use a similar one that has a DP switch.

Are you competent to turn off the supply, and remove the switch to check for loose connections, damage, damp or dirt? I have known a water leak wash damp dirt into such accessories, causing a flashbang and trip.

Would you be able to obtain a compatible new switch locally, if it turns out to be faulty?

 

[Benedictus]

Okay thank you i will check

 

[Murdochcat]

Wow, are those socket “holes” really round?

 

[Highway Man]

Looking at the picture, I suspct it will be damaged and corroded through years of steam rotting it. ?First job would be to replace it regardless of any other fault on the circuit.

 

[Benedictus]

I manage to diagnose it , the socket is the issue , will be replacing it

I know that

I was just immensely surprised to see such a cooker isolator switch like that. Rare to say the very least.

Botswana and South Africa use the same type of electrical Plugs and Socket-Outlets
Type M.

These Plugs and socket-Outlets use three round pins, with one larger pin for grounding.
This plug is officially known as BS 546.
The Type M plug was once the UK standard plug,
before the change over to the Type G plug (BS 1363) - after WWII.

While the BS 546 type has mostly been displaced in the UK by the BS 1363 standard,
some 40 countries still use Type D (5 Amp)
and
15 countries use Type M (15 Amp)
