American indoor extension cords, commonly used for electrical power extension in indoor settings, generally possess the following characteristics:
Length: Extension cords come in various lengths to accommodate different needs. Typical lengths range from a few feet to 25 feet or more, allowing users to extend the reach of electrical devices from a power outlet.
Wire Gauge: The wire gauge or thickness of the cord determines its capacity to handle electrical current. Common gauges for indoor extension cords include 16 AWG (American Wire Gauge) and 14 AWG. Thicker gauges can handle higher current loads.
Plug and Receptacle Type: American indoor extension cords typically feature a three-pronged plug with two flat blades and a rounded grounding pin. The receptacle end provides multiple outlets to connect multiple devices simultaneously.
Ampacity: The ampacity or current-carrying capacity of an extension cord depends on its wire gauge. Common indoor extension cords are rated for 13 amps or 15 amps, allowing them to handle a range of electrical appliances and devices.
Safety Features: To ensure safety, indoor extension cords often include features such as grounding, polarized plugs, and built-in surge protectors. These features help prevent electrical shocks, protect connected devices from power surges, and reduce the risk of electrical fires.
Insulation and Durability: Extension cords are insulated to protect the conductors and prevent electrical contact. The insulation material is typically made of PVC (polyvinyl chloride) or rubber. Cords designed for indoor use are not usually as rugged as outdoor cords but are still durable enough for typical household applications.
Color and Design: Indoor extension cords are commonly available in white, black, or neutral colors to blend with indoor environments. The design may include a flexible cord with molded plugs and strain relief to prevent wire damage near the plug ends.
UL Listing: Reputable indoor extension cords are certified by Underwriters Laboratories (UL) or a similar organization to meet safety standards. Look for the UL mark or equivalent certification to ensure the cord's quality and safety.
It's important to choose an extension cord that matches your specific needs and complies with local electrical codes. Additionally, always follow the manufacturer's instructions for safe usage and avoid overloading the cord with excessive electrical loads.
