Requirements for Cooker
connections
The cooker switch or cooker control unit is typically installed
to provide the following 2 functions:
1. To provide a means of isolation so as to facilitate
replacement or repair of the cooker unit without
having to isolate at the consumer unit. Table 53.2 of
BS 7671 provides guidance as to the standard for such
devices. BS EN 60669-2-4 is a suitable standard for
isolation switches for household and similar
applications. Also identified in Table 53.2 is BS 4177, for
cooker control units to provide the function of isolation.
2. Switching off for mechanical maintenance to avoid the
risk of burns or mechanical injury when cleaning or
maintaining the cooker.
A current rating of up to 45A is sufficient for most household
cooking appliances.
The position of such a unit should be should be such that it is
accessible and convenient for use. It should not be
positioned directly behind the cooking surface in order to
avoid someone needing to reach over the appliance in order
to access it. The horizontal distance should be such that the
switch is under the control of anyone needing to access it.
A maximum distance of 2m is likely to meet this requirement.
The final connection to the cooker unit will usually be by
means of a cooker connection unit on the wall behind the
cooker itself. This enables easier connection and
disconnection for maintenance or replacement.
Where two stationary cooking appliances are in the same
room, one switch may be used to control both appliances
and is recommended that neither appliance is more than two
metres from that switch.
“ It is recommended that the cooker
control switch is within 2m of the
appliance ”.
