recommends attaching the PX3 enclosure to the top or
bottom of the panelboard’s enclosure so that the two enclosures are joined
without a barrier . It is best to do this before the panelboard is mounted to the
structure .
To join the two enclosures, the top or bottom endplate of the PX3 may
be removed . Similarly, the top or bottom endplate of most commercial
panelboards may be removed .
If your panelboard is TOP-FEED, remove the bottom endplate of the
panelboard and the top endplate of the PX3 .
™
If your panelboard is BOTTOM-FEED, remove the top endplate of the
panelboard and the bottom endplate of the PX3 .
™
Attach the PX3 to the panelboard using the supplied collar hardware and
screws . Refer to the illustration above showing an PX3 being mounted to the
bottom of a panelboard .
Tip: Use of small C-clamps helps hold the parts in place while the screws
are inserted and tightened.
Note: The panelboard and PX3 enclosures can also be joined together using a
close nipple, lockwashers and bushings. Such installations, however, may limit
the ability to pass conductors between the two enclosures.
