INSTALLATION

This rating is applicable to installations served by a reliable normal utility source.This rating is only applicable to variable loads with an average load factor of 80% of the standby rating.The standby rating is only applicable for optional standby power where the generator set serves as the backup to the normal utility source.

Use the “Wattage Reference Guide” provided and mark those circuits you consider “critical” or “essential”. Make sure you and your installer consider the generator’s altitude above sea level and the ambient temperature range when determining total generator load.

Disconnect Box Mounting Guidelines

The disconnect box is a NEMA Type 3R enclosure suitable for outdoor use. Installations must strictly comply with all applicable codes, industry standards and regulations.

Guidelines for mounting the disconnect box include:

•The disconnect box must be installed with appropriate hardware for conduit connections.
