11.3 Electricalwiring
Connection of the whole electrical system and any heating
system controls to the electrical supply must be through a
common isolator.
Isolation should preferably be by a double pole switched fused
spur box having a minimum contact separation of 3mm on each
pole. The fused spur box should be readily accessible and
preferably adjacent to the boiler. It should be identied as to its
use.
A fused three pin plug and shuttered socket outlet may be used
instead of a fused spur box provided that it is not used in a
room containing a xed bath or shower.
