Manual Transfer Switch
Indoor version
(consists of 2 breakers with handle interlock)

Economical Panel/Link switches.  Supplied with a double pole utility breaker and a double pole generator breaker that are interlocked to prevent both from being closed at the same time.  This eliminates the danger of backfeeding to the utility, endangering utility repair crews.  It also prevents utility power from feeding into your generator and causing damage.  The TRB also has provisions for 4 to 8 branch circuits using single-pole breakers or 2 double-pole breakers.

Standard features include NEMA 1 indoor cabinet suitable for surface mounting, knockouts for hard wiring and UL Listing.  Service entrance rated which allows this to be connected directly to your power company meter.  Provided with preinstalled main generator and main utility breaker with feed-thru lugs for connecting your load wiring.  Generator meters included for 60A input and below.  An optional male inlet is available for 50A generator inputs and below.  This product can be used as a main panel or a sub-panel.  Made in USA
