Cooker Installation

A separate final circuit should be employed to supply a cooker. It should be connected to a separate way on the distribution board and terminated at a cooker switch. This switch should be a Double Pole type rated at a minimum of 45 A. The switch feeds a cooker connector unit, which may be made “live” even when not connected to a cooker. A heat-resistant flexible cord should be used to connect between the connector unit and the cooker. A cooker circuit is normally wired in 6 mm2 cable and 4 mm2 flex, protected by a 32 A MCB or fuse.
