why inspect and test?

Inspection and Testing is important to establish that an installation remains safe to use, and meets British Standards to remain compliant with legislation.

As you will see, the connection between the earth clamp and the gas pipe on this commercial installation has failed due to corrosion. This is an important connection since it ensures that unsafe voltages do not appear on the pipework.

Inspection and testing verifies that the electrical installation has not deteriorated into a dangerous condition, and ensures that the installation remains safe to use.

What happens during inspection and test?

The following tests/conditions are carried out / verified…

Verification of the continuity of protective conductors including main and supplementary equipotential bonding

Continuity of ring final circuit conductors

Insulation resistance (checks condition of the insulation around wires)

Protection by SELV, PELV or electrical separation

Basic protection by a barrier or enclosure provided during erection

Insulation resistance/impedance of floors and walls

Polarity

Earth electrode resistance

Protection by automatic disconnection of the supply

Earth fault loop impedance

Additional protection

Prospective fault current

Check of phase sequence

Functional testing

Verification of voltage drop
