v Attachment plugs complying with National Electrical Manufacturers Association
(NEMA) L6-30P
v Appliance couplers complying with International Electrotechnical Commission (IEC)
Standard 320, Sheet C13 and C14
Power cables used in other countries consist of the following:
v Electrical cables, Type HD21 or HD22
v Attachment plugs approved by the appropriate testing organization for the specific
countries where they are used
v Appliance couplers complying with the International Electrotechnical Commission
(IEC) Standard 320, Sheet C13 and C14
