Note 1: Field wiring must be made by a UL-listed and CSA certified ring lug terminal
connector sized for the wire gauge involved. The connector must be fixed by using
the crimping tool specified by the connector manufacturer.
Note 2: Be sure to consider the capacity of the circuit breaker to be used.
Note 3: Be sure to use a larger wire gauge if power line length exceeds 66 ft (20m).
