The Best Extension Cords for Any Garage

An extension cord usually consists of insulated wire, a plug, and some sockets at one end. This is a convenient and safe way to utilize limited power outlets. You can use these cords to connect power tools, appliances, or anything other electric device required when you’re working in your garage.

Why Do We Need Extension Cords for the Garage?

Many people utilize their garage space for a lot more than just parking their vehicles. Some might set up a craft room in there, which will require electricity for glue guns, electric sanding machines; vacuum cleaners, and so on. Others could have a woodworking shop set up in their garage, which might require the use of power tools, focused lighting, space heaters, etc. The needs might overlap, but an extension cord is a budget-friendly way to get the power you need. Not everyone has the budget to install power outlets just where they need them, so these cords come in handy when working on a project.

How to Choose the Right Extension Cord

There are, however, several factors you need to take into account before making your extension cord purchase. Just getting the cheapest kind in bulk might seem like a good idea at first, but this results in a compromise on quality. Low quality extension cords are more likely to overheat and become a fire hazard. They might also fray, break, or short out at the most inconvenient moment shortly after purchase.

Even if you buy quality extension cords, make sure you read up on how to organize these cords in your garage.

To stay safe and ensure that you can get your work done without much hassle, keep the following considerations in mind when you get extension cords for your garage:

1. Their Intended Purpose

One of the first things you need to sort out is whether you’d need these cords for only indoor use, or whether they would also need to be used out of doors at times. Indoor extension cords are not meant for outdoor use, while outdoor versions are also fine when used inside.

While a garage is technically indoors, the location of the nearest power outlet might make the extension cord trail along on the ground outside. You may also want the cord for outdoor use at times. In such cases, opt for an outdoor extension cord when you’re narrowing down the choices.

The next purpose to think about is what the cord will be used for on a regular basis. Does it only have to power small appliances, or are there power tools and space heaters to consider as well? How often will you be using to cord and what are the conditions like in your garage? All these answers will be handy in deciding what extension cord will be best for your situation.

2. Gauge Rating

A wire gauge means the diameter or thickness of the internal wire in an extension cord. This thickness is given an AWG (American Wire Gauge) number. The thicker this wire is, the smaller its number will be (ranging anywhere from 0 to 40). If you want a sturdy outdoor extension cord, the gauge rating should be from 10 to 18 AWG.

The gauge rating will usually be paired with the number of wires that the cord holds. A 16/2 cord denotes a wire with 16 gauges and two wires inside.

3. Safety Rating

Before you choose any extension cord, make sure it’s a reliable one with a safety rating from independent testing agencies. These agencies include UL (Underwriters Laboratories) or ETL (Intertek). A certification from organizations like these will assure you that the cord meets all international and federal safety standards.

4. Power Capacity or Rating

Amperes or amps measure the volume of electricity that flows through the conducting wires in an extension cord. The voltage measures the resistance of the electric flow. Checking out these values is essential; you need to plug in appliances accordingly. If a cord doesn’t have enough power rating to properly power a certain tool of appliance, it risks overheating and catching fire.

5. Voltage Drop

While it might be possible to find extension cords that measure over a hundred feet, you don’t really need anything so long for tasks in the garage and around the house. The length of the extension cord will affect the amount of lost voltage through electric resistance due to the distance. This phenomenon is called the voltage drop, basically meaning that they lose the strength of the electric flow.

This loss of voltage is why it’s best to determine the shortest possible extension cord that’s needed to get your tasks done.

6. Types of Sockets and Plugs

There might be two prongs or three of your extension cord plug. If there are three, it indicates a grounded cord, meaning increased safety and gives another path for the electric currents to flow through. If you’re using large appliances or heavy duty power tools with your extension cord, get one with three prongs.

The socket is where you directly plug in whatever you want the power for. The sockets are usually in the form of a strip. Where there are options for both two and three-pronged plugs. If your appliance has a three-pronged plug, make sure that your extension cord has one too.

7. Strength of Jacket

The act covering the wires should be effective for safe function and insulate the inside. This could be made of nylon, plastics, vinyl, rubber, and similar material to prevent exposure to the elements along with electrical leakage. A quality jacket will also prevent overheating.

The material, purpose, and strength of any extension cord’s jacket are usually apparent through the use of various letters. Here are some of the letters you may find printed there:

  • S: Flexible cord for general use
  • W: Suitable for outdoor use
  • J: 300 voltage insulation (without J, there would be a 600-volt insulation)
  • P: parallel wire construction
  • T: Material is vinyl thermoplastic.
  • E: Material is TPE (thermoplastic elastomer rubber)
  • O: Oil resistant

The table below helps to summarize the various main features of extensions cords and what they provide:

Gauge Rating Range of Length Amps Suitable Uses
16/2 Light Duty 25 to 100 feet 13A (0’-50’)

10A (50’-100’)

Christmas lights and fans
16/3 Light Duty 25 to 100 feet 13A (0’-50’)

10A (50’-100’)

Lights, fans, and tools like hedge trimmers
14/3 Medium Duty 25 to 150 feet 15A(50’-100’)

13A(50’-100’)

Corded lawn mowers, power drills
12/3 Heavy Duty 25 to 150 feet 15A (0’-100’) Chain saws, industrial vacuums
10/3 Heavy Duty 25 to 150 feet 15A (0’-100’) Power tools, generators
