Manual Transfer Switch
single circuit
20A, 30A, 50A
125V & 125/250V
The Pro/Tran® CSR single-circuit transfer switch is easy to install and operate, connects portable generator to one branch circuit or load. Originally designed for supplying generator power to traffic signals. This switch is also perfect for those large single loads that are too big for the 15A or 20A limitation of the Pro/Tran® 4, 6, 8 and 10 circuit transfer switches. An example would be an electric water heater fed from a 2 pole 30 amp breaker. Now required by Article 702.6 of the 2002 National Electric Code to prevent inadvertent back feeding of electric power from generator into utility system which can be a safety hazard.
Standard features include NEMA 3R outdoor cabinet suitable for surface
mounting, knockouts and hub provision for wiring and UL Listing.
Inlet included but without meters.
