Installation Requirements

Install the SC1008 in a location that is accessible by qualified personnel for testing of the transfer
function using either a laser pointer (or similar) or the onboard test switch.
The SC1008 installs to a flat surface, has four conduit entry locations, and includes a universal
mounting plate with four mounting holes. Mounting and conduit hardware are provided by others.
Note:
with Article 300 of the National Electrical Code (NFPA 70).

Ambient Environment

NEMA Type 1 Enclosure suitable for installation location that conforms to the following ambient
environment:
0°C–40°C, 5–95% non–condensing humidity
•

Electrical Specification

Note:
Use copper wire only, minimum 75°C conductors.
Normal and Emergency Rated Operational Voltage Input
120–277 VAC +/- 10%, 50/60 Hz
•
Load Rating
Supports a continuous load of up to 20 A for tungsten and resistive load types, and supports
•
electronic ballast loads of up to 16 A (80% of the switch rating)
Continuous load current not to exceed 100% of the switch rating
-
Transfer Initiation
When normal power is lost, meaning the voltage drops below 85 VRMS, the unit transfers the
•
output load to the emergency power source.
When normal power is restored, meaning the voltage rises above 90 VRMS, the unit transfers
•
the output load to the normal power source.
Short Circuit Current Rating
Short circuit capacity of 10 kA
•
SC1008 BCELTS
Suitable for use in other spaces used for environmental air (plenums) in accordance
Continuous load current not to exceed 100% of the switch rating.
