I have a 1000 watt submersible pump at the bottom of my garden. It pumps land drainage water from a sump to a drainage outlet. The pump has a 3 pin plug and is currently plugged in to a weather proof extension reel. I'm currently digging up garden and would like to replace the extension reel with something more permanent. Would it be acceptable to run a 2.5 mm 3 core SWA Cable to the bottom of garden (buried, warning tape etc) and fix a weatherproof socket on a concrete post. I have a 4mm radial circuit in the house on a 32a mcb. This circuit only has 2 double sockets on it and a light that's stepped down to 5 amps. I was considering having this 4mm radial circuit extended to the outside wall and fitting a weatherproof junction box on the outside and running the SWA to this. I'm also planning on adding a shed to the garden and I'd like to have a single double socket and light in there. Would it be feasible to run another 3 core 2.5mm swa cable from the same junction box to the shed? Sparky will be doing it, but this is what I'm gonna ask for. House was rewired 2 years ago (17th) and is TN-C-S. The cable run to pump is about 20 meters. Cable run to shed is about 10 meters.
