Caravan tt tncs

[midgetman]

Hi
There is a caravan that moves between two properties. One property is Tncs supply the other tt. Both feed caravan via external socket on property which are 16amp radial (rcd protected ) .

Caravan plugs into this via 25 meter lead. Caravan has small cu with 30 amp rcd,, 16amp mcb, 6 amp mcb,(sockets, lights). Only TV , PC and two led lights.

Caravan cu is earthed to caravan chassis.

I read about tncs supply on caravans and rods etc but what is best way when it moves every week between tt and tncs..

Thanks
