Abstract: A junction box for electrically connecting a furnace to a service panel and providing power and control signals to fixed appliances. The junction box includes a panel connection adapted for connecting with the hot wire, the neutral wire, and the ground from the panel. A furnace connection is provided for connecting with a hot wire, a neutral wire, a ground, and a number of control wires from the furnace. A fuse and a disconnect switch are mounted in the junction box and wired in series between the hot wire connection of the panel connection and the hot wire connection of the furnace connection. A condensate pump outlet is wired to the hot wire connection portion of the panel connection on the line side of the disconnect switch. Humidifier and air cleaner outlets are coupled to the connections of the furnace connection used for control wires from the furnace.
