ABSTRACT:
A forced-air electric furnace is provided with an electric disconnect block mounted within a recess in the furnace body forming an electric box. The electric box is closed by a cover panel which includes an aperture through which a disconnect block extends to establish electrical continuity between the feed-in wires and the furnace heater coils. The plug has side shoulder areas which extend beyond the aperture in the cover panel to prevent uncovering the box without disconnecting the electricity.
