Blowing sockets and popping RCD

[Josh555]

A client asked me to add two sockets in their bedroom

I took power from two sockets in the lounge which is behind the bedroom wall.

I ran a cable out of each socket for the new socket

The problem is it now is tripping the RCD and blowing the old Existing sockets and light switches

But the new sockets I added still work fine

The old existing sockets and switche are blown and unusable

When I try to reset the RCD It pops and Sparks down

Any idea to why this is happending

if the old sockets were on a ring, and one leg has popped out... the new sockets, being connected will still work, but theres maybe another floating live touching the metal back box.

can you take photos of the back of the sockets? there might be something obvious to us that you havent seen

The thing is the client phone back saying there’s no power and the RCD is popping down and sparking so I went back same night, and opened up the sockets I touched the connections were fine the socket sparked and popped while the socket was open so no loose lives

Sockets "blown"?!! What does that mean?!

What are your IR results for that circuit?

Good luck

The actual sockets I took power from sparked an blew

The wind blows. You mean the mcb tripped off? If that happened there's no way the new sockets could be still live

no the actual sockets sparked and blew in front of me
The mcb never tripped once only the RCD

I still dont know what you mean. But anyway, if the RCD tripped the other sockets def were not still live. Did you do any testing?

No tests on the ring were carried out

 

[mattg4321]

No tests on the ring were carried out

So how do you expect to find the problem without testing? Apologies if I’ve got the wrong end of the stick here, but if I’m dealing with a symptom of tripping pretty much the very first thing I do is IR testing

On the assumption you're trained and experienced, what does that tell you ?

so I went back same night, and opened up the sockets I touched, the connections were fine, the socket sparked and popped while the socket was open so no loose lives

Did you leave the socket sparking and popping when you left or have you isolated it / them?

Well with all due respect you'll be hard pushed to get much help with that admittance, not good.
