Every season in Ottawa, Ontario, comes with many different weather challenges and implications. We thought it’d be the perfect time to inform residents about outdoor extension cords to keep their electrical systems working properly and safely during any season in Canada. Choosing the right outdoor extension cord can help prevent house fires when lighting up your exterior or running power to your vehicles. 

How to Buy the Right Outdoor Extension Cord? 

The first and most obvious thing is to read the packaging on the cord itself for its intended use. Outdoor extension cords will have a higher amp rating as well as outdoor electrical usually requires heavier electrical loads. Another identifier is that outdoor extension cords use a bright rubber, vinyl or plastic that covers the cord and acts as insulation to protect from temperatures, moisture, and sunlight. All outdoor extension cords will have 3-prong plugs which are safer for use and reduce electrical hazard risks. Indoor extension cords can be 2-prong plugs or 3-prong plugs but outdoor extension cords will never have only 2-prongs.

Reading Extension Cord Packages:

When you are reading the labels when buying extension cords they use letters as codes to describe the type of jacket (insulation) and cord use. Common labels are: 

  • “S” – identifies a general use and flexible cord
  • “W” – identifies that it is rated for outdoor usage and wet areas 
  • “J” – identifies hard service and that it has 300V insulation
  • “P” – identifies that it has parallel wire construction
  • “T” – identifies that the jacket is made from vinyl thermoplastic 
  • “E” – identifies that the jacket is made from TPE rubber 
  • “O” – identifies that it is oil resistant

If you are unsure what label you need for your usage and amperage for your outdoor extension cord, contact us to learn more and the suggested cord for your use. 

Outdoor GFCI Outlets

The exterior of your home should have ground fault circuit interrupter (GFCI) protected outlets for use with outdoor extension cords. This will increase your protection and reduce the risk of fire by automatically shutting off the power if it senses there is moisture or water.
