Hi everyone ,
I have a new build Rewire coming up. Currently the meter is in a green cabinet at the front of the driveway and the new house will be around 30 metres away. I have done all the calculations for the cable which is fine. The earthing system is currently a TT system with a spike (will renew) behind the green cabinet. I will be installing an RCBO consumer unit in the house. Currently there is a “temporary” supply which has a switch fuse in place, my question is would I need to protect the new SWA cable from the cabinet to the new house with an RCD rather than a switch fuse as a TT system, I was thinking about a fuse box housing with a 100ma Type S RCD so no to not interfere with upstream RCBOs? Any advice would be great first real time coming across this exact scenario! Also would there need to be earth rods near the house or will the earthing at front of driveway be ok. Thanks J
