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.
The ASCO SERIES 300 Manual Transfer Switch is the perfect load transfer solution for commercial and municipal applications. Choose from many diverse customization options to suit your individual needs. The SERIES 300 is good for both residential and industrial applications.
