INSTALLATION REQUIREMENTS
Before installing the transfer switch, review the following requirements:
3.4.1. Installation Codes/Permits and ATS Sizing
Suitable permits are typically required by local jurisdictions having authority prior to
installing standby generator sets and automatic transfer switches. Per NEC Article
702, Automatic transfer switches shall be sized for either a) entire load whole house,
load calculation per NEC 220, or b) Pre-selected “EM” panel(s) of load being served
or optional standby panel and transfer switch, or c) automatic load shedding feature
to reduce total load imposed on the generator, not to exceed the capacity of the
generator. The TS 910 transfer switch has automatic load shedding capabilities built-
in when load shedding control contact is connected. Refer to Load Shedding section
of this manual for further details.
3.4.2. Installation Location
The standard TS 910 transfer switch is designed for indoor wall mounting. For
applications requiring outdoor wall mounting, a NEMA 3R door kit is optionally
available. The transfer switch must be installed in an environment where the
temperature range is within +5° to +122° Fahrenheit (-15° to +50° Celsius) and
humidity range not exceeding 5%-95% non-condensing.
3.4.3. Power Cabling
All power cabling entering/exiting the enclosure must be installed in suitably sized
conduit per NEC requirements. Ampacity, type and voltage rating of current carrying
conductors must also comply with NEC requirements and local jurisdictions having
authority.
