Junction box socket spur

Maybe it’s me, but I’ve always found it was easier to have too much, and trim it back, than to find you have to add a couple of inches.

Oh definitely, I just thought there was sufficient here. There's approx 8cm cable after the grommet, what's a standard length to cut these too usually?

Never measured it. You get to know how much, and add a bit.

I’ve found that sometimes, when you come to change a socket, that the wires are just long enough for the old one. But the new one has a different terminal layout. Meaning that at least one of the conductors is too short.

Maybe it’ll be ok. Let’s see how you get on.

Absolute minimum would be so that the cable can reach all 4 corners of the box easily.

Thanks all, just test fitted the faceplate and it goes on fine.

I've now cut the pvc outer sheath right down and I'll wire the socket in when I'm done sanding.

Appreciate all the help and I'll bear in mind cables lengths for future sockets.

There's absolutely no harm in having them longer than you need. In the case of a spur as you have, there's only one cable to accommodate, so plenty of room for a bit of slack.

Even with two cables, you can afford a bit more length.

Just think about having to fit a different socket where the terminals are in different places or swapped round etc....

Not true. The so called regs are not statutory.

You stand in court and say that and they will bend you over and shove the regs so far up you it hopefully will stop you talking

Are you related to eric?

These issues will virtually never get anywhere near any sort of Court. However, if they somehow did, there is only one sentence of relevant law (Part P of the Building Regulations), and the government-issued guidance relating to that law ("Approved Document P") makes it clear that compliance with BS7671 is not 'mandatory', but is just one way of complying with the law.
