The other day I had to connect a static caravan so the house holders can live in it while their house is being refurbed, the house is tncs
no I know your not ment to export the earth and I understand why, so I installed a earth rod, 78 ohms.
the main board in the caravan has 30ma rcd, but I could not bring my self not to connect the 3rd core in the swa to bring the earth fom the house also. I know the situation that if the dno's neutral fails this earth could end up running the neutral to the house etc.
but what's worse? This earth, now become neutral burnt in the swa or, some one leaning on the outside of the caravan, which would be at 230v with the dno's neutral fault and stood on the ground, possible wet?
they would then complete the circuit from the bonded caravan through them to ground and back to the supply transformer or dno's next earth spike.
any comments?
