should not drop below one megohm per 100
feet of busway.

10. For UL Outdoor, NEMA 3R, and GM Drip-Proof

rated installations: Remove only downward-
facing
weep-hole plugs and shield plugs so
that condensation and accumulated moisture
can drain out as suggested by these
standards.

11. For IEC 529 IP43, IP54, IP65, or IP66 rated

installations: Do not remove the weep-hole
plugs during installation if the busway is to
meet any of these water-spray ratings.
Remove (and be sure to reinstall) the plugs
only as a maintenance procedure to
determine if water has entered the busway.


Installation Tips

Outdoor busway is only rated as such when it
is completely and properly installed. GE
normally recommends setting and tightening
joints at the nominal length and sealing each
joint as the installation proceeds. The
contractor should consider the weather and
the need to seal each joint versus the need to
make length adjustments later.

Use a reversed joint cap (gasket side out) as a
joint-length gauging tool or align the holes in
the joint and housing ground plates.

Use a straight edge, string, level, plumb line,
and square to set runs.

Use a 3/4-inch or 19-mm socket wrench on
joint bolts, and tighten to 50 lb-ft (68 N-m).

Depending on which cap bolt is provided, use
a 9/16-inch (14-mm) socket wrench and
tighten to 25 lb-ft (34 N-m) for the 3/8 bolts or
a ½-inch (12-mm) socket wrench and tighten
to 14-18 lb-ft (19-24 N-m) for the 5/16 bolts.

Do not adjust the joint length with the shields
or caps installed, as this will damage the
gaskets.

Cap gaskets should be replaced whenever a
joint cap is removed, except that if a cap
gasket has been compressed and taken a set,
it may be reused if:
– It is reinstalled in exactly the same location

and orientation without any joint
readjustment
. Use the compressed outline
in the gasket to set this location.

– It has recovered to 80% of its original

thickness within 12 hours. In this case, it
may be reused in any location as if it were
new.

Spare gaskets are provided.

If any parts are damaged during shipment or
installation, replacement parts should be
ordered from the factory. On-site repairs of
damaged parts should not be attempted.
