Type of installation

Installation Energised

Stage of construction
Consumer Mains

Labelling clear and accurate.

Current carrying capacity.

Voltage Drop.

Aerial installation conditions.

Connection of wiring.


Location. e.g. Not in restricted location, access and egress.

MEN connection Intact.

Basic protection against contact with live parts. e.g. insulation and enclosures.

Fault protection (protection against indirect contact with live parts) by the use of automatic disconnection of supply. Check that the consumer mains have over current protection.

Protection against the spread of fire.

Protection devices installed and suitably rated for over-current protection, arc fault protection and discrimination.

RCD's installed on applicable circuits.

Isolating devices e.g. main switches.

Connecting devices. e.g. earth bar, neutral and active links.

Connection and fixing of wiring and switchgear.

Identification and labelling of electrical equipment. e.g. switchboard markings and circuit identification

Protection against external influences. e.g. mechanical damage, effects of UV light.

Wiring Systems

Conductor Size. Check current carrying capacity and derating of cables and associated CPD.

Labelling clear and accurate

Support and fixings.

Connections and enclosures. Check to confirm that cables are suitably terminated. e.g. under benches.

Underground wiring systems. Check installation method. Cat 1 etc.

Overhead wiring systems. Check clearances from structures, vegetation and ground.

Segregation from other services. Gas, water, solar.

Protection against external influences. e.g. mechanical damage, effects of UV light.

Installation of cables in accessible areas of the ceiling space. e.g. near manhole, crossing roof battens and trusses.

Electrical Equipment (appliances, lights etc)

General condition of electrical equipment.

Isolation devices installed where required.

Isolating device for range installed within 2 metres of the hob.

Down lights installed in accordance with the wiring rules.

Equipment installed as per manufacturers requirements. e.g. anti-tilt bracket for upright range.

Fixing and support of equipment adequate

Equipment suitable for the operating environment. e.g. IP rating.

Protection against hazardous parts. e.g. guarding, screening etc.

Availability of user manuals, operating instructions.


Earth electrode installed. Painted and tag attached to main earthing conductor.

Earthing conductors. e.g. size, identification.

Equipotential bonding conductors. Pool fences, water piping, slab reinforcing wet areas

Connection, joints and terminations adequate.

Protection against external influences. e.g. mechanical damage, effects of UV light.

Conductive building materials connected to earth where required. e.g. contact with single insulated cables.

Creation of an earthed situation that may require earthing of additional electrical equipment.
