What is an EICR?
An EICR (Electrical Installation Condition Report) is as the name implies a report into the condition of the electrical installation and to highlight any safety shortcomings, defects or deviations from the current revision of the electrical regulations BS7671.
Who should perform an EICR?
An electrical installation condition report should be performed by a competent electrician with the necessary experience and extensive knowledge of the type of installation that he or she is testing.
What are the processes of an EICR?
This is where the electrician will survey the electrical installation before he/she commences with the electrical testing. The visual inspection will highlight broken or cracked devices, where devices may have been installed in the wrong location, or if there have been overloading or over heating problems.
Electrical testing with the use of electrical test meters, including:
- 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.
- 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
- 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 body to the ground (earth)
