An extension cord must have adequate wire size (AWG or American Wire Gauge) for safety, and to prevent loss of power and overheating.
To determine the minimum wire size required, refer to the chart:
|Minimum Gauge for Cord Set Total Length of Cord in Feet|
MORE THAN NO MORE THAN
|AMERICAN WIRE GAUGE|
The smaller the gauge number of the wire, the greater the capacity of the cable, that is 16 gauge has more capacity than 18 gauge. When using more than one extension to make up the total length, be sure each individual extension contains at least the minimum wire size.
Before using an extension cord, inspect it for loose or exposed wires, damaged insulation, and defective fittings. Make any needed repairs or replace the cord if necessary.
Please Note: Tight connection between your extension cord and outdoor power equipment is essential for proper operation. Failure to maintain a tight connection could result in damage to the cord and/or tool being used, regardless of the gauge of the cord being used.
