Position indication contacts provide Form “A and “B” position con-
tacts.
E. Source 1 Position: Provides one Form “A” and one Form “B”
contact per customer connection.
F. Source 2 Position: Provides one Form “A” and one Form “B”
contact for customer connection.
16. Integral Overcurrent Protection
Provides thermal-magnetic overcurrent protection integral to the
power switching device(s). All Feature 16 options include a

overcurrent condition, then “Lockout” is displayed on the ATS
Controller display and automatic operation is prevented until the
appropriate source is manually reset.
B. Both Power Source Switching Devices: Provides integral over-
current protection on both Source 1 and Source 2 power
switching devices.
E, Source 2 Power Switching Device: Provides integral overcur-
rent protection on the Source 2 power switching device only.
N. Source 1 Power Switching Device: Provides integral overcur-
rent protection on the Source 1 power switching device only.
18. Metering and Communications

lyzer for monitoring the Source 1 line side circuit.
P. IQ Analyzer - Source 2 Line Side Metering: Provides an IQ Ana-
lyzer for monitoring the Source 2 line side circuit.
Q. IQ Analyzer with Selector Switch for Source 1 or Source 2
Line Side Metering: Provides an IQ Analyzer with a source
selector switch for monitoring the Source 1 or Source 2 line
side circuit.
R. IQ DP-4000 - Source 1 Line Side Metering: Provides an IQ DP-
4000 for monitoring the Source 1 line side circuit.
S. IQ DP-4000 - Source 2 Line Side Metering: Provides an IQ DP-
4000 for monitoring the Source 2 line side circuit.
T. IQ DP-4000 with Selector Switch for Source 1 or Source 2
Line Side Metering: Provides an IQ DP-4000 with a source
selector switch for monitoring the Source 1 or Source 2 line
side circuit.

assembly with removable link.
Feature 16 must be selected sepa-
rately.
A. Service Equipment Rated Transfer Switch without Ground
Fault Protection: Provides Service Equipment rating for an
application that does not require ground fault protection.
B. Service Equipment Rated Transfer Switch with Ground Fault
Protection: Provides Service Equipment rating for an applica-
tion that requires ground fault protection.
41. Space Heater with Thermostat
Provides a space heater and adjustable thermostat. External con-
trol power is not required.
C. Space Heater with Thermostat - 400 Watts: Provides a
400 Watt space heater with an adjustable thermostat.
42. Seismic Certification
Provides a Seismic Certified Transfer Switch with certificate for
application that is Seismic Zone 4 under the California Building
Code, the Uniform Building Code, and BOCA.
3.7 Enclosure
The rugged steel switch enclosure is supplied with four door
hinges, regardless of enclosure size, to insure proper support of
the door and door mounted devices. The hinges have removable
hinge pins to facilitate door removal. The doors are supplied as
standard with thumbscrew and padlock latches. Cable entry holes
are the customer’s responsibility.
The door is used to mount a variety of lights, switches, and push
buttons, depending upon the options required for a particular
switch. All switch doors are supplied with a heavy duty plastic
accessory panel in place, whether or not external devices are
required. When lights, pushbuttons, or switches are required,
they are normally mounted in the plastic door mounted panel.
Transfer switch enclosures and some internal steel mounting
plates, such as the transformer panel mounting plate, go through
a pre-treatment cleaning system prior to painting to insure a dura-
ble finish. Should the enclosure become scratched and in need of
touch up paint, use ANSI 61. All remaining steel is galvanized.
The standard switch enclosure is NEMA Type 1 for general indoor
use (Table 4).
