What is an Electrical Installation?
The regulations published under notice R2920 in the Government Gazette 23rd October, 1992 say that an electrical installation is where any machinery is used for the transmission of electricity from a point of control to a point of consumption on any premises. Vehicle, telecommunication, and certain other equipment including that of the supply authority is excluded from the definition.
Who is responsible for the Safety, Safe Use and Maintenance of an installation?
These same regulations state clearly that the USER or LESSOR is responsible for the installation.
How do you know the installation is safe?
By ensuring that the installation is covered by a valid certificate of compliance. The law requires that the USER must possess a valid certificate of compliance for the installation being used.
What electrical test must be carried out?
The tests required are:
1 - Continuity of all bonding conductors.
2 - Resistance of earth continuity conductor.
3 - Continuity of ring circuits (if applicable).
4 - Earth loop impedance test: main switch.
5 - Elevated voltage of neutral.
6 - Earth electrode resistance (if required)
7 - Insulation resistance.
8 - Voltage (Main DB) no load.
9 - Voltage (Main DB) on load.
10 - Voltage at available load (worst condition)
11 - Operation of earth leakage units
12 - Operation of earth leakage test button
13 - Polarity of points of consumption.
14 - All switching devices, make and break circuit
