NOTE:
1- All component parts shall be ETL or UL listed or classified.
2- Conduit & fitting sizes shall be per the NEC (Nat’l, Elec. Code)
3- The conductors shall be sized for 125% of the full load amps the
motor being used per the NEC (#14 AWG. minimum)
4- Ground the motor case per the NEC as follows: 15A= #14,
20A= #12, 40A= #10.
