• If a manual transfer switch is not in place, the fusible links must be physically disconnected to isolate the facility from the commercial power grid so electricity will not backfeed to the electrical grid from the generator.
• The personnel installing the generator may not have the correct tools or equipment to remove these fuses.
• This could require utility company support to accomplish. They may not be readily able to support your need in a timely fashion as they are working to reestablish the overall electrical distribution system as rapidly as they can.
• There are costs associated with installing a manual transfer switch, but the costs are significantly less expensive as compared to the costs of installing a generator. Keep in mind, manual transfer switches do not have the same operations and maintenance requirements as a generator.
