ASCO SERIES 300 Service Entrance Manual Trans. Switch

For Commercial or Light Industrial Use

When power fails, businesses suffer. For some organizations, a permanent generator is too costly. Instead, a permanent means for quickly connecting a portable or temporary generator can make economic sense. Installing a manual transfer switch and a connecting means can provide an adequate and cost effective solution. This equipment can provide access for an alternate power source when a generator malfunctions or is removed from service for maintenance.
