Manual Transfer Switch
(consists of 2 breakers with handle interlock,
4 spaces for branch breakers, feed-thru lugs, meters)

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.
