Square Schneider Electric Surgebreaker

Square Schneider Electric Surgebreaker

When surge protection is installed at the electrical panel, it helps protect all of your home devices – including the ones that aren’t plugged into a power strip. The Electric Surgebreaker can make sure that nothing gets destroyed. 

Easy to install and saving space, it’s a wonderful whole house surge protection to consider in your home. It protects everything from home electrical wiring, expensive LED lights, computers, game consoles, and all the way to appliances like washers/dryers, and fridges. 

Surges come from multiple sources and range from immediate loss of electronics with larger strikes, or simply far less life expectancy of your electronics and appliances from dealing with surges. A protector like the Square Schneider Surgerbreaker is fantastic in preventing issues, while still remaining easy to install and acquire. 

The only thing to be aware of is that you will need to keep several extra parts for the breaker, once it gets tripped by a large surge it can only absorb the one and will need to be replaced. That said, you only need to replace the one part and not the whole installation – which saves you money and time. 

  • Easy to install.
  • Saves space.
  • No reset button; part needs to be replaced after a big surge.

Eaton Ultimate Surge Protection

Eaton is a top choice for whole house surge protectors, saving your electronics and appliances from surges. 

If you’re familiar with breaker panels, you can install this small box yourself within an hour or less, though it is recommended that you have a proper electrician do so just to make sure that everything is set correctly. A fair number of reviews on Amazon have said that the white wire was rather short for their panels and needed to be adjusted accordingly. Not a problem, but rather just as a known issue. 

It does require a 50A Pole Breaker that you may have to purchase separately if you don’t already have one, which isn’t uncommon with whole house surge protectors. Just be sure to have space in your breaker panel, and if not you should opt for a smaller protector for you. 

There are two LEDs that indicate it’s working or if the fuse has been blown, in which case it just needs to be replaced and you can go on with being protected from electrical surges. 

  • Decent install.
  • Indicator LEDs.
  • Wires may be too short.
  • Needs to be compatible with your set-up.
