Need some advice please. I've fitted the above unit to my outside wall to take power to a shed about 2.5 m from the house. I have used SWA (3 core 2.5mm) cable for this.
The box is about 45cm above ground level, and I'm using the bottom entry for the SWA. For neatness, I have used some PVC conduit to sheath the SWA before it goes down under a concrete path to the shed. My question is :- Do I have to fit a CW 20mm cable gland to the box, or is it possible to use MK's 20MM Plain Conduit Entry Push Fit Adaptor, and twist and sheath the steel strands and terminate it to earth in the box in addition to the earth feed in the cable. Would this method be ok, as the SWA would be fully enclosed in the conduit which goes down into the concrete?
Inside the shed, it comes up through the concrete base, and is fixed using cleats to the wooden frame, and its terminated into a metalclad RCD socket with a BW 20mm Gland. I have also taken a feed to power a strip light via a 5amp FCU and switch.
