Abstract: The invention provides an arrangement for shielding non-metallic motor leads from damage during servicing within the cabinet of a forced air furnace having a double inlet centrifugal blower housing containing a fan wheel and a direct drive motor which is resiliently mounted to the blower housing. The arrangement includes a channel-shaped raceway and a junction box which are aligned on the blower housing support plate in an arrangement permitting the raceway to be secured to both the junction box and the side of the blower housing in a way which does not interfere with the resilient mounting of the motor within the housing. The arrangement is also adapted to accommodate protecting the motor and capacitor leads of an external capacitor type motor.
