Wiring
CAUTION: Before installing or performing any service on a Greengate system, the power MUST be turned
OFF at the branch circuit breaker. According to NEC 240-83(d), if the branch circuit breaker is used as the
main switch for a fluorescent lighting circuit, the circuit breaker should be marked “SWD”. All installations
should be in compliance with the National Electric Code and all state and local codes.
NOTE REGARDING COMPACT FLUORESCENT LAMPS: The life of some compact fluorescent lamps (CFLs) is
shortened by frequent automatic or manual switching. Check with CFL and ballast manufacturer to determine the
effects of cycling.
