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 insu-
lation 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.
