Farm pump - underground power supply cable type
Posted: Mon Jun 15, 2020 10:12 am
Hi all
Cable type selection question
I'm looking at running a 500m cable underground to a farm water pump station. (Pump (4 amps) + Lights + GPO)
My plan was to run 4 core Neutral screen 95mm AL but have discovered that is not a common cable.
I don't trust the farmer not to cut the cable via Mole plough so we are going down 1m plus I was going to have the supply on RCD.
Based on price and my current thinking i'm going to run 70mm 4 core Circular TPS AL and run a separate Earth Wire. (reduce the supply fuse size)
The other way is to forget the RCD and just drive in a Earth at the pump shed.
Is this how others would do this job?
