What are the most common myths about electrical safety?

When it comes to electrical safety, there are many misconceptions that people have. Perhaps you’ve heard some of them: - Electrical cords must be cut before being plugged in.

- You can’t have a computer and a lamp plugged in at the same time.

- You need a special ground fault circuit breaker for every single outlet in your home. Or, you need a new breaker box just for your kitchen.

- You must unplug your small appliances like hair dryers, coffee makers, or blenders when not in use.

These are just a few examples of electrical safety myths that are not only false but can also be dangerous. Fortunately, many of these misconceptions are easily debunked and can help you protect yourself from electrical injuries. Let’s take a look at some of the most common electrical safety myths and their explanations:

Mistake #1: Electrical Cords Must Be Cut Before They Can Be Plugged In.

This is one of the most common electrical safety myths out there. While it’s true that electrical cords must be cut before they’re plugged in, that doesn’t mean you have to literally cut the cord. You can safely plug in an electrical cord even if it’s not cut. Why? Because even if the cord is frayed, you can still plug it in safely. Electrical cords are designed to safely conduct electricity from the source (plug) to the device (light bulb). They may not look like much, but those copper wires are actually quite capable of handling a substantial amount of voltage.

Mistake #2: You Can’t Have a Computer and a Lamp Plugged In At the Same Time.

This is also one of the most common electrical safety myths. In fact, it’s almost impossible to have a computer and a lamp plugged in at the same time. One of the key principles of electrical safety is that you must isolate any electrical source that isn’t being used. For example, if you have a lamp plugged in, but there’s also something plugged into the computer, you must first unplug the computer before plugging in the lamp. If you don’t, the lamp could pick up a stray electrical current from the computer and cause a fire. This is because computers and lamps are both sources of electricity and must be isolated from each other.

Mistake #3: You Need a Special Ground Fault Circuit Breaker For Every Outlet In Your Home.

This is also another common electrical safety myth. While some outlets may have a circuit breaker, not all do. And even if they do, they don’t all need a special ground fault circuit breaker. This is an especially important point to note since the National Electrical Code requires a GFCI for any outlet where food is prepared. This is because food contains a lot of water, which is a high conductor, and could therefore create a ground fault. So, while this may be a common misconception, it’s not something that many people need to worry about.

Mistake #4: You Must Unplug Your Small Appliances When Not In Use.

The thing about electrical safety is that nothing is set in stone. While you may have heard that you must unplug small appliances like hair dryers, coffee makers, or blenders when not in use, the truth is that the National Electrical Code doesn’t actually require this. To be safe, you should unplug these appliances only if they come with a manual switch to shut them off. If they don’t, then you don’t need to unplug them.

Bottom Line

There are many common misconceptions about electrical safety, but some of them are easily debunked. The key is to understand the basic principles of electrical safety. For example, you need to keep appliances, cords, and plugs away from each other at all times, and you must also keep extension cords and extension outlets away from wall outlets.
