Why did my voltage tester just explode?

[SJD]

I was trying to check whether the fused spur is part of the main loop (it looks like it is - it has 2 twin and earth cables feeding into one of the "input" set of the live, neutral and earth terminals, and one twin and earth feeding from the output to a junction box which isn't feeding anything)

Just to add, the fact that there are two cables into the FCU "input" does not necessarily mean it is on the ring (loop), it could be a spur that someone has then taken a second spur from, don't assume what is already there is correctly connected ...

Aye ..... I always think that if you're to assume anything, assume that it's wrong until you can prove otherwise.

No, what I meant was that there are 2 fused spur switches which don't appear to be doing anything...so I wanted to know why they are there (hence testing them - not the voltage tester)

It then feeds to the next socket, which then feeds somewhere else, so I thought it's likely to be part of the loop. Should you take a spur from a spur, and if so, how many times can you do that?

you can, as long as they're appropriately fused. if they're not fused, then you're only allowed one spur from one socket.

There's a diagram in the back of the BGB that tells you all about that Jeansie.

I'm not sure that Jeansie knows what the BGB is never mind have one.

That's why I mentioned it mate. Surely there is a point where well meaning help runs the risk of giving someone misleading advice through only having partial facts?

I agree.

That very thing has been discussed and argued on this board many times.

Uh huh. I'm all in favour of well meaning advice, I've seen it stop people in their tracks before they get fried but tbh, I do have concerns when I see a shorted neon screwdriver that the owner asks why it happened then gets advice on spurs. Jeansie, this is no way intended to be a dig at you but really if you don't understand the basics please get a spark to help.
