It has become increasingly popular in a kitchen that instead
of having several fused connection units around to feed the
appliances, one central point is utilised instead. This usually
involves a grid switch plate with modular switches and fuses.
Overload protection needs to be considered by the designer.
A ring final circuit is the usual method of feeding the sockets
and appliances which assumes the power consumed will
be distributed from several points on the circuit. Should a
central control point be used however, the power for all those
appliances are effectively distributed from that one point.
Overload protection may not be provided in accordance with
regulation 433.1.1. The designer will need to assess the
current demand at this point and ensure this would not
exceed the current rating for long periods of either part of the
ring.
As an alternative a radial system may be considered for the
appliances having central control. The cable feeding this
control point would need to be suitably rated however for the
load and hence may result in a large csa.
