Default Re: An unusual BS546 plug

The GEC Heating and Cooking Appliances catalogue for 1911 has two electric ovens (with hotplates), rated at 2.5kW and 3.4kW respectively. The catalogue says that all appliances were available for voltages between 100V and 250V, voltage to be specified when ordering, and that the lower-voltage versions cost extra. Given their size and weight, and that GEC's highest rated plug for domestic use at the time was 10A (*), the cookers would probably have been connected via fixed wiring. This would almost certainly have been the case for the 3.4kW oven, which was offered in two versions, one with its switches on the side of the oven, the other on a discrete wall-mounted control panel.

(*) 25A and 50A plugs were offered for theatrical and industrial use.
