What is Periodic Inspection & Testing?

The 'Electricity at Work Regulations 1989' in Regulations 4(1) and 4(2) lay down the requirement to ensure that an electrical installation should be designed, installed, constructed and maintained in a safe manner at all times. The basis for periodic inspection and testing is derived from Guidance Note 3 of the 'IEE Wiring Regulations BS7671:2008'.

Inspection and testing of an electrical installation generates a Periodic Inspection Report which is a condition report supplemented by testing results. The Periodic Inspection Report will normally consist of:

• Client information and details of the installation
• Supply characteristics and earthing arrangements
• Observation and recommendations
• Extent and limitations of testing
• Summary of the inspection
• Inspection and test schedules

The inspection of an electrical installation should be carried out in accordance with 712-01-03 of the 'IEE Inspection and Testing Guidance Note 3'. Conducted by a team of two competent qualified inspectors, the inspection can highlight a significant percentage of defects on an electrical system. These may include (amongst others): exposed conductors or terminations: broken covers, conduits or trunking: the lack of earthing on conductive parts and inadequate support or damage to cables.

The testing of an electrical installation follows BS7671:2008 and comprises of:

• C.P.C continuity
• Ring circuit continuity
• Insulation Resistance
• Polarity
• Earth fault loop impedance
• Prospective fault current
• Operation of residual current devices
• Functional testing

Testing is carried out as far as is reasonably practicable as defined in EaWR 1989.
