Entry and Intake of Electrical Service ~ the local electricity supply
company is responsible for providing electricity up to and including
the meter, but the consumer is responsible for safety and
protection of the company's equipment. The supplier will install the
service cable up to the meter position where their termination
equipment is installed. This equipment may be located internally or
fixed externally on a wall, the latter being preferred since it gives
easy access for reading the meter † see details on the previous
page.

Meter Boxes † generally the supply company's meters and
termination equipment are housed in a meter box. These are
available in fibreglass and plastic, ranging in size from 450 mm
wide ¾ 638 mm high to 585 m wide ¾ 815 mm high with an overall
depth of 177 mm.

Consumer Control Unit † this provides a uniform, compact and
effective means of efficiently controlling and distributing electrical
energy within a dwelling. The control unit contains a main double
pole isolating switch controlling the line and neutral conductors,
called bus bars. These connect to the fuses or miniature circuit
breakers protecting the final subcircuits.
