Electrician Jobs Domestic. Cable Overheating?

[Brian Brown]

I have a 13 amp socket in my kitchen which, from behind the switch plate a green sticky substance appears occasionally on the wall. I have just removed the socket plate and revealed that the substance appears to be coming from the three core wire sheath.
I suspected one of the core cables was overheating but the socket is never overloaded and is in continual use and has never shorted out.

Could anyone please tell me what might be causing the problem. I guess the cure will be to get the cables replaced.

It is known a chemical migration the cable is probably not overheating. This is caused by plasticisers added to pvc years ago to make it more flexible and a chemical reaction is taking place causing it to migrate from the pvc hence the green goo. It may be worth getting your electrics checked over to see the extent of it and replace the cables as necessary. Wash your hands thoroughly if you have touched it.

Hi - yes as per @westward10, a quote from the article on green goo below.
"Di-isoctyl phthalate is a toxic substance and suitable protective clothing should be worn when handling waste materials. Special attention should be paid to hygiene when working on contaminated installations. "
I think the comment is more intended for someone working on an installation with multiple affected cables, but you get the drift.

Thank you both for your replies. Rather an interesting outcome. I have cleaned everything up as best I can and I will get round to getting the cable replaced.Thanks again. Regards. Brian.
