The statement of standard as below:The values specified above are doubled if all controls have an off position in all poles. They are also doubled if:– the appliance has no control other than a thermal cut-out; or– all thermostats, temperature limiters and energy regulators do not have an off position; or– the appliance has radio…
off position: stable position of a switching device in which the circuit controlled by the switch is disconnected from its supply or, for electronic disconnection, the circuit is de-energized.NOTE The off position does not imply an all-pole disconnection. With reference to the content in the NOTE, both all-pole disconnection and single-pole disconnection are a stable…
all-pole disconnection: disconnection of both supply conductors by a single initiating action or, for multi-phase appliances, disconnection of all supply conductors by a single initiating actionNOTE For multi-phase appliances, the neutral conductor is not considered to be a supply conductor. Single-phase power: An AC power system composed of one live wire and one neutral wire.Three-phase…
