Mounting Guidelines

The transfer switch system circuitry is enclosed in a NEMA Type 3R
enclosure suitable for indoor/outdoor use. Guidelines for mounting
the enclosure include:
• Install enclosure on a firm, sturdy supporting structure.
• The transfer switch enclosure must be installed with
minimum NEMA 3R hardware for conduit connections.
• To prevent switch contact distortion, level and plumb the
enclosure. This can be done by placing washers between the
enclosure and the mounting surface.

• NEVER install the switch where any corrosive substance
might drip onto the enclosure.
• Protect the switch at all times against excessive moisture,
dust, dirt, lint, construction grit and corrosive vapors.
A typical automatic transfer switch installation is depicted below. It
is best if the transfer switch is mounted near the utility meter, either
inside or outside. Discuss layout suggestions/ changes with the
owner before beginning the system installation process.
