I have recently wired up some outdoor lighting by cutting in to an existing armoured cable that runs down the side of my house and fitting a junction box (plastic, IP56) where the outdoor lighting is fed from via flex.
The armoured cable then continues from the junction box underground to my shed where I'm going to fit another small consumer unit to supply lights and sockets for the shed.
Unfortunately the armoured cable runs in to my understairs cupboard but has been chopped about 6' short of the consumer unit.
What's the best way to extend the armoured to the CU?
Could I just run the armoured cable in to another junction box and then run 2.5 T+E to the CU?
If I did this, would the armoured need to be glanded as its indoors anyway?
Finally, what size MCB would this require and would it need to be RCD protected?
