What happens in an electrical inspection?

Each electrical circuit in your house has a group of tests performed on them. The tests are as follows;
Continuity of CPC and bonding – This is to check that your protective conductors (earths) are electrically safe and correctly connected.
Continuity of ring final – Tests to ensure that there are no breaks or inter connection in any of the conductors/circuits feeding your sockets.
Insulation resistance – This is a test to measure the quality of the insulation between conductors (live, neutral and earth).
Polarity – A test to confirm that all live conductors are connected into live terminals.
Loop impedance – This test confirms the impedance of each circuit, which is used to calculate the speed a circuit will disconnect under fault.
RCD – If there is an RCD present in the installation it is tested to ensure it trips within the times give in BS7671 (electrical regulations).
Functional testing – To ensure that switch etc are working correctly.

House Rewire in Chesterfield, Derbyshire
“ My problem started with me trying to do my own DIY for a basic task,I thought it would save me time and money.How wrong I was!! I managed to short circuit the house and blow one of the main fuses plus some other things which I didnt realise Id done!!This was in an evening,so I was really glad when I called these guys and they sent someone round straight away. „
