3 Reasons to Avoid Extension Cords Without a UL Mark

Non-listed cords often lie about their ratings A UL-listed cord has been tested to safely handle the amps and volts printed on it. A no-name cord from a discount bin might claim 15 amps but use 18-gauge wire that will overheat long before that.

UL, ETL, or CSA marks mean independent verification These marks confirm the cord’s gauge, insulation, and plugs can actually do what the label says. Without them, the manufacturer just printed numbers that look good.

An underrated cord under load is a fire hazard Cheap cords get hot, melt, and start fires. Pay the extra few bucks for a UL mark or buy from a trusted brand like Coleman Cable or Southwire.
