TM 5-3895-374-24-1 ELECTRICAL POWER REQUIREMENTS ELECTRICAL WIRING Refer  to  the  air  compressor’s  serial  label  for  the  unit’s voltage   and   amperage   requirements.   Ensure   that   all wiring  is  done  by  a  qualified  electrician,  In  accordance with the  National  Electrical  Code.  Use  electrical  conduit to protect the wiring to the compressor, and between the magnetic starter, pressure switch, and motor. MAIN POWER PANEL Provide circuit breaker or fuse protection at your main power panel. MAIN POWER DISCONNECT Install a main power disconnect in the line from the panel to the compressor. The disconnect must be located near the   compressor,   for   ease   of   use   and   safety.   When turned  OFF,  the  disconnect  shuts  off  all  power  to  the compressor. When it  is  turned  ON,  the  compressor  will start and stop automatically, as directed by the pressure switch. USE A DEDICATED CIRCUIT For   best   performance   and   reliable   starting,   the   air compressor must be installed on a dedicated circuit, as close  as  possible  to  the  electrical  power  panel.    Low voltage  will  cause  difficult  starting  or  an  overload  Low voltage can be caused by a low supply voltage from the local  power  company,  other  equipment  running  on  the same  line,  or  inadequate  wiring  If  any  other  electrical devices are drawing from the compressor’s circuit, It may fall to start. Low  voltage  to  the  compressor  can  be  caused  by  too small    a    wire    size    for    the    distance    between    the compressor   and   the   power   source.   The   longer   the distance,   the   larger   the   wire   diameter   must   be,   to overcome  the  inherent  voltage  loss  caused  by  the  wire resistance   Refer   to   the   National   Electrical   Code   to determine proper wire size for your circuit. If the wiring Is not adequate, the voltage will drop from 20 to  40  volts  at  startup.  Low  voltage  or  an  overloaded circuit  can  result  in  sluggish  starting  that  causes  the magnetic  starter  or  circuit  breaker  to  trip,  especially  In cold  conditions.  Use  time  delay   fuses   on   the   circuit, because  the  compressor  will  momentarily  draw  several times its specified amperage when first started. 200-2009 (page 3-631)
