* Suggested wire size based on United States NFPA 70 National Electrical Code 2005 edition published by the National
Fire Prevention Association.
Listings are from table 400.5(B) for flexible cord of certain types rated for 75 deg C in ambient temperatures up to 30 deg
C. Using wires of lower temperature rating or different insulation type may require larger wire size. Derate for higher
ambient.
These are suggestions only. Always refer to your local and national codes that apply to your region for final determination
of correct wire type and size.
