* 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 ambi-
ent temperatures up to 30 deg C. Using wires of lower temperature rating or different insula-
tion 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.
