Powering Life for Modern Humanity

208V, 480V Portable Generator Quick Connection (GLQC) Switchboard


The FS2-Series allows quick and safe connection of a mobile generator set to facilities experiencing loss of power or temporary loadbank for permanent generator testing. This portable generator quick connection switchboard is rated Type 3R for outdoor installation. Permanent installation and connection of the switchboard to the facility power distribution system will minimize any unplanned power outages. Therefore, it provides easy and safe connection of a temporary loadbank. The primary components of the portable GLQC Quick Connection Switchboard are cam-lok type receptacles and a fixed mount insulated case circuit breaker.
