This example of work is of a new installation of TT system supply and mains distribution board in a warehouse for farm equipment to providem the customer with lighting, power and heating and additional power for outbuildings.
We installed and earth stake and inspection pit to achieve an acceptable earthing resistance for this system. A time delay 100ma/80amp RCD was then installed for overall protection which was supplying a populated RCBO mains board that offers 30ma additional protection.
All the kit was mounted in a clear area, away from possible damage from machinary and livestock.
This job was carried out in North Baddesley, Hampshire.
