I'm a 77yr retired sparks whose regs. related memories are a bit cloudy.
On my sons land there is a TN-C-S single phase supply to an existing barn with an 80 amp company fuse
A supply to a second barn is needed using an 3 core swa to be buried. The total load of both barns will be well under 80 amps
Does that swa need rcd protection?
Do I earth both ends of steel armouring?
Cable run is 55 metres absolute max load of 30 Amp
Would 10mm cable be correct?
How best to bond steel barn frame to earth?
