On the day the electrician will conduct various tests in order to issue an electrical certificate. Below are the most common processes they perform on the day which you may want to keep for reference.
Visual Testing
A visual test will be conducted prior to the testing sequence to identify faults or problems
Dead Testing
Continuity testing: a test to check if there are any badly connected conductors (wires)
Insulation resistance testing: this test is to make sure that the electrical insulation material surrounding the conductors is intact.
Polarity: this test is to check that the connection are connected in the right sequence
Earthing arrangement testing: this check is to make sure that the earthing arrangement complies with regulations and that all connections are sound.
Live Testing
Earth fault loop impedance testing: this test is to check that if a fault did occur, that the system meets requirements to cause a disconnection of the supply within the time limit specified. May be calculated depending on the installation
RCD testing: on modern electrical systems RCD’s and RCBO’s are regularly fitted, these devices react to electricity missing from the circuit or installation such as when a person is receiving an electric shock as the electricity passes through his/her body to the ground (earth).
Coding
The codes used to determine whether there are non-compliances or issue with the electrical installation and are numbered C1 to C3. These codes will be entered on the Electrical Installation Condition Report, along with a description of the nature of the fault, and will determine whether a ‘Satisfactory’ or ‘Unsatisfactory’ report will be applied to the installation.
Code C1 ‘Danger present’: There is a risk of injury and that immediate remedial action is required to remove the dangerous condition.
Code C2 ‘Potentially dangerous condition’: Urgent remedial action required, this should declare the nature of the problem, not the remedial actions required.
Code C3 ‘Improvement recommended’: This code more often than not implies that while the installation may not comply with the current set of regulations, complies with a previous set of regulations and so is deemed to safe although this safety can be improved upon.
