ELECTRICITY SUPPLY - Page 7
A 240 volts ~ 50Hz. single phase electricity supply fused at
3A must be provided in accordance with the latest edition of
the lEE wiring regulations and any other local regulations
that may apply. The current rating of the wiring to the boiler
must exceed 3 amperes and have a cross sectional area of
at least 0.75mm
2
in accordance with BS6500 1990 Table 16.
The method of connection to the electricity supply MUST
facilitate complete isolation of the appliance, preferably by
the use of a
fused three pin plug and unswitched, shuttered socket outlet,
both complying with the requirements of BS1363.
Alternatively, connection may be made via a fused double
pole isolator having a contact seperation of 3mm in all poles
and serving the appliance and system controls only.
