Power Surge Protection in a Thunderstorm

A Clap of thunder. A lightning strike. Flickering lights. Without knowing it, you’ve fallen victim to a power surge — which can burn up a few thousand dollars of electronics in the blink of an eye. When spring and summer weather starts rearing its head, a lightning strike is the most common cause of a power surge

A power surge, or an electrical surge, happens when a burst of electricity enters your house through the main panel. That excess electricity surges into ANY electronics plugged into an outlet, frying them like bacon and eggs.

A power surge can destroy your electronics

Your TV, your computer, your game systems: literally thousands of dollars — in the form of your beloved electronics — up in smoke. Don’t risk that disaster this spring and summer. Get the scoop on power surges, the electronics you need to protect, and our ultimate defense against power surges during a thunderstorm.

Power Surges: what are they?

Like we said, power surges occur when an excess amount of electricity flows into your home through your main electrical panel, rushing into any appliance plugged into an outlet.

The power surge exposes your electronics (and your electrical system) to far more energy than it can withstand. It’s not uncommon for us to have to replace main electrical panels following a severe thunderstorm. While all appliances require electricity to work, excess electricity irrevocably destroys the sensitive components inside — frying them like a delicious breakfast.

Power Surges: The Cause

The majority of external power surges are caused by lightning — however the risk isn’t lighting striking your house, but a much larger target, such as:

  • Electrical Transformers
  • Power lines
  • Electrical substations

Electronics/Appliances at Risk from a Power Surge

Now that winter is wrapping up, we need to start paying attention to the possibility of severe spring and summer weather. You can’t predict or control where lighting strikes (that would be a Marvel-worthy superpower, if you could.) Instead, all you can do, is ensure your appliances are safe during every single thunderstorm.

protect your valuable electronics from a power surge

There are two ways to do that:

  1. Unplug EVERY single valuable electronic/appliance/piece of technology
  2. Team with Mister Sparky for a whole house surge protector.

Here’s a semi-complete list of everything you need to unplug during a thunderstorm:

  • Televisions
  • Computers /laptops
  • DVD/Blu Ray player
  • Sound system
  • Game systems
  • Blender
  • Toaster
  • Electric stoves
  • Microwaves
  • Refrigerators
  • Washing machine
  • Dryer
  • Dishwasher
  • Phones or tablets that are charging
  • Lighting (especially if you’ve upgraded to LEDs)

That’s a lot to remember for every summer storm. Also unplugging some of these big ticket appliances isn’t exactly the easiest thing either.

Power Surge Protection

Power strips you buy at a hardware store may be great for stopping energy vampires and saving on your electric bill, but they don’t stand a chance against a power surge.

power surge protection

A whole house surge protector attaches to your main electrical panel. In the event of a massive power surge, this heavy duty surge protector keeps you 100% protected.

Any excess electricity flowing into your home electrical system is automatically redirected to your home’s grounding wire. Rather than the electricity burning up thousands of dollars of appliances and electronics, it safely returns to ground.

That’s right, you’re completely protected during any spring or summer thunderstorm. No need to unplug appliances, and no need to worry.
