Breaker Connection.
11-3.2.1 Whenever possible, connect parallel-type surge protectors to a spare breaker
in the associated breaker panel. In addition to providing a close electrical connection
that minimizes lead length, the breaker provides traditional overcurrent protection for
faults between the breaker and the surge protector. Also, the breaker provides a
convenient means of deenergizing the circuit to work on or replace a surge protector.
