mused:


I've just discovered that the 6mm cable leading to my electric shower
has a join: Two lengths have been joined using a 30A junction box. I
think I once heard that 6mm cable should not be joined; is that
correct?

Nope.

If so, what is the actual danger/risk? I wondered if anyone
could explain. How concerned should I be?

As long as the junction box has been well made off and connections are
sound then you have no need to worry.

Ideally you want to have all cables as continuous lengths but as long
as joints, in any size cable, are correctly made off then thefre isn't
a problem.
