ABSTRACT:
The present invention provides an electric heating apparatus comprising a plurality of electric heaters and cords for supplying electric power to the heaters through a connector, wherein the connector consists of two separable members, the one member (the primary connector) of the connector has a plurality of contacts and at least one conductor, the cords being separately connected to the contacts, the conductor electrically short-circuiting two contacts of the primary connector which are so selected that the conductor can form a part of a circuit for supplying electric power to a desired heater, the another member (the secondary connector) of said connector has a plurality of contacts being connected only with predetermined contacts of the primary connector, and the contacts of the secondary connector form a part of the circuit for supplying electric power to the desired heater with the contacts and the conductor of the primary connector, wherby heaters to be supplied with electric power can be determined by selecting the two contacts short-circuited by the conductor. Accordingly, the electric heater capacity of the present heating apparatus is readily changeable merely by changing the connection of the conductor for use with another power supply with different maximum currents capable of flowing safety through a branch circuit.
