Motor Starters
**************************************************************************
NOTE: The motor control requirements should be
coordinated with Section 16402, "Interior Wiring
Systems" and will depend on field conditions. The
following types of motor starters should be used as
a guide only. When electrical equipment is
connected to heavily loaded power circuits, the
starting current may cause an excessive voltage drop
on the circuit.
