Gauge and Amperage Capacity
The wire gauge indicates the cord’s thickness and capacity to carry electrical current. For air conditioners, a minimum of 14 gauge is recommended to handle up to 15 amps and 1875 watts. Using a cord with lower gauge number (thicker wire) reduces the risk of overheating and power loss.
Length
Cord length affects performance; longer cords can cause voltage drop, reducing appliance efficiency. Choose the shortest length that meets your needs while allowing comfortable placement. Common options range from 6 feet to 20 feet.
Plug Design and Space-Saving Features
Flat or angle plugs allow cords to sit flush with walls, maximizing space behind furniture or appliances. This is especially important when cord placements are in tight indoor spaces.
Grounded 3-Prong Plugs
A 3-prong grounded plug is essential for safety with air conditioners and large appliances. It provides a reliable ground connection to protect against electrical shocks and device damage.
Durability and Insulation
Look for cords with heavy duty vinyl or PVC insulation that resists moisture, abrasion, and heat. A flexible yet robust jacket ensures long-term use without cracking or damage.
Certification and Compliance
Choose cords that are UL listed, ETL certified, or have equivalent safety approvals to guarantee quality standards and safe operation.
Intended Use
Make sure the extension cord is rated for the specific application such as indoor appliance use, air conditioners, refrigerators, or power tools. Usage outside its design scope can be hazardous.
