• Rated for 300 VAC, 10 A minimum
• Rated for at least 70 °C (158 °F) and applicable to the installation environment
• If installed outdoors, the power cord jacket insulation is rated for outdoor use
• Not less than 0.82 mm
• A power cable with a three-prong plug (with ground connection) that is applicable to the supply
