Fitted a Velux window over the weekend and there are a couple of cables running directly underneath. Cant be moved out of the way, so need to extend them.
I'm fine with extending the electric cable (using a 30A junction box), but what about the earth cable - assume this cant be extended similarly using a junction box?
