Hi all,

I’m new here and after some advice on a sub main circuit

I have a 3 core SWA feeding a log cabin from a house. The house has an existing TT system and I’m just wondering what the best way to supply the log cabin would be?

What would I need up front to protect the SWA, I’m presuming a sub board with and RCD/RCBO from the house end and then a separate earth Rod for the log cabin. With 30mA protection on all log cabin circuits?
Any information and help with this would be greatly appreciated. Thanks ??
