Why it’s important to get the right kind of extension cord

It is important to have the right kind of extension cords on the HVAC job site because the cord is responsible for carrying the heavy duty electrical load. Instead of being hooked directly to the power source, the extension cord is an extension of the electrical wiring of the residence or industrial location.

The HVAC technician’s extension cord must be able to withstand the wear and tear of repeated use day in and day out. The extension cord will be dragged across a variety of terrain, up and down the stairs, around corners and everywhere on the job site.

This is a piece of equipment that will be used often. A durable cord is a necessity so that you will not be replacing it often. In addition, ordinary household wiring will not handle the power load without tripping a breaker, and the job won’t get done without the correct extension cord.

You should choose a cord that is at least 50 feet long because it will reach into the attic or beneath the home. The 50-foot length will also allow you to set up your sawhorse and sheet metal a safe distance away from the home and bystanders. The regular size indoor extension cords are not suitable for powering anything more than a lamp or a fan because if the cord is not thick enough nor long enough, the cord will overheat and melt down. It can cause a fire and a disaster.

The industrial heavy duty extension cords can carry the heavier electrical load without melting down and causing extensive problems for both the homeowner and the HVAC tech. HVAC technicians regularly use power tools that are high in amps, and to safely operate it, HVAC technicians need to use an extension cord with a lower gauge number of conductive wire. The longer the power cord, the thicker the wires and the lower the gauge number of wire required.

Longer cords tend to tangle or get in the way when you are working. We recommend that you have a couple of these on hand because if you need the extra length, you can hook them together with ease. This extension cord can easily handle the power of a sawzall or a corded drill.
