AUTOMATIC, NON-AUTOMATIC AND
MANUAL TRANSFER SWITCHES
Enclosures meet all current applicable NEMA and UL standards for con-
duit entry, cable bending, gutter space and shielding of live components.
NEMA 1 Enclosures
NEMA 1 Transfer Switches are supplied with a front door only.
They can be mounted in a corner or against a wall. Access to
cable space can be via either side, bottom, top, or the rear.
NEMA 3R Enclosures
Additional 2” (5.1cm) clearance on each side of enclosure for
hooded vent patterns.
Requires appropriate rear-end clearance based on 26-34”
(66-86cm) door (800-2000A) or 31” (61cm) door (2500-
4000A).
NEMA 3R Transfer Switches are supplied with front & rear doors.
They can be mounted against a wall (allowing for hooded vent
pattern clearance), but not in a corner. Access to cable space is
via rear only.
NOTE: When open switch is mounted in customer enclosure, a vent pat-
tern similar to that used on a Culter-Hammer enclosure must be utilized.
