How to Know if an Extension Cord is for Outdoor Use?

There are many ways you can identify an outdoor rated extension cord. Below are some of the easy ones.

1. Rating Indicator

When looking for an extension cord for outdoor use, you may want to see if it has a “W” sign printed on the cover or insulation. This letter stands for weather-resistant compound, which means it is heavy-duty and rated for outdoor usage.

You can see this sign on the packaging, along with the other features of the cord.

2. Insulation

Insulation is another feature that distinguishes an outdoor extension cord. Its insulation is typically significantly thicker and constructed primarily of heavy-duty rubber, plastics, or vinyl, making it heavier and more robust.

3. Color

The color of the insulation can also be the basis to determine whether the cord is rated for use outside. Normally, you’ll see bright yellow, blue, and green extension cords for outdoor use.

There are orange extension cords waterproof and brown extension cords waterproof products as well, perfect for wet and moist conditions.

4. Plugs

It is also possible to identify if a cable is rated for outdoor applications by looking at its plug. An outdoor cord is always equipped with three prongs on the plug.

Three prongs indicate a grounding feature that should go with a GFCI outlet for additional safety. This is essential to prevent the risk of electrical hazards that can result in electrocution or fire.

5. Amperage

One of the attributes of outdoor extension cords is a higher amp rating compared with indoor ones. This means they can hold more power, making them perfect for energy-intensive devices.

Technically, the wire gauge size or AWG can determine the amp rating of a cord. As the number of AWG decreases, the wire size increases, or the lower the number, the larger the wire.

The AWG is often seen with the rating indicator on the cord or the packaging label if it is new.
