  10. THE ELECTRICAL REFERENCE DATABASE gives electricians, engineers,        
  11. designers, and panel shop operators one place on your computer where you
  12. can find those little notes that only experience produces. In this case 
  13. a professional has given you his experience and created a forum for you 
  14. to add your own.

  42. Motor databases provide information as to full load currents, motor over
  43. current protection rating, the size or guage of the wire required to    
  44. connect one motor of that particular horsepower in a general purpose    
  45. application, the conduit trade size required to house the wire, the NEMA
  46. size starter recommended, the amperage and the recommended fusing.      
  47.                                                                         
  48. The present data is referred to as "seed" data just to get you started. 
  49. You may add and delete data as you like. Each data base can handle a    
  50. maximum of 2.1 billion entries.                                         
  51.                                                                         
  52. Each database is menu-driven and complete with its own help function    
  53. and notes field. Use this data base as a tool -- not as a replacement   
  54. for the NATIONAL ELECTRICAL CODE manual. All information assumes a      
  55. single motor installation. Consult your NEC manual for the details of   
  56. your particular installation.
