NOTE
* Suggested wire size based on United States NFPA 70 National Electrical Code 2011 edition published by the
National Fire Prevention Association. Listings are from table 400.5(A)(2) 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. De rate for higher ambient.
These are suggestions only. Always refer to your local and national codes that apply to your region for final deter-
mination of correct wire type and size.
