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 � in ambient temperat�res �p to �0 deg �. �sing �ires of lo�er temperat�re rating or di� erent ins�� deg � in ambient temperat�res �p to �0 deg �. �sing �ires of lo�er temperat�re rating or di� erent ins�� � in ambient temperat�res �p to �0 deg �. �sing �ires of lo�er temperat�re rating or di�erent ins��
lation type may require larger wire size. De rate for higher ambient.
These are s�ggestions only. Al�ays refer to yo�r local and national codes that apply to yo�r region for final
