How do I safely undo and re-attach this connector? it connects an armoured cable to the power outlet in the shed. I'll turn off the mains obviously. And then do I just undo it with a spanner and pull it out?
I need to re-route the cable and need to disconnect it to do that.
That is a gland connector which seals the outer cover of the cable and grips the protective outer wires then the conductors continue into the box / device to the connections.
So you have to undo the internal conductors and then release that cinnector.
Make sure the supply is off.
We always used to undo the internal fixing nut and the connecting wires and leave the gland assembled to the cable - much easier.
