Project Description

We were asked to upgrade an old fuse board to the latest specification Dual RCD / MCB consumer unit including upgrading the Main Equipotential Gas Bonding, Main Earth and Supply Cables . The installation was a TT system, connected to a earth spike but upon investigation we discovered it was possible to connect to the supply networks earthing system which improved the earth loop reading of the incoming supply from over 200 Ohms to 0.17 Ohms! This amongst other benefits guarantees fast disconnection times in the event of an earth fault.
We were also able to determine after a series of tests on ALL circuits a faulty twin socket (very high earth resistance on the right side outlet).

We can check your earthing system, taking test readings and advising on if any improvements are possible. Contact us to organise a site survey.

Where possible we use high quality ‘Crabtree’ branded consumer units with the optional back plate system in order to comply with Amendment 3 of the wiring regulations and all works are certified under the Part P scheme for building regulations and logged with the relevant local council.
