Overview
Enclosure Base
The HRE-819 enclosure base is a molded plastic unit. The base contains the air bypass valve, pressure relief valve,
order wire port, stub cable, and mounting hardware.
In the event of damage to the housing, the housing can be detached from the base and replaced. This precludes the
need to blow the splice case and resplice a new unit stub into the main feeder cables. Whenever the base and
housing are separated and then reattached, torque the connecting bolts to 40 inch-pounds in the sequence shown
in

Enclosure Housing
The enclosure housing
chamber has six double-wide slots and a slot for the maintenance pressure contactor plug. Each plug-in slot
contains connectors that accommodate both the plug-in unit and its associated protectors.
Seal the housing covers to the housing with a reusable gasket, which forms an airtight seal when the lid bolts are
properly torqued to 40 inch-pounds in the sequence inscribed on the lid
