Surge protector?

I have had a problem with my pump and a light earlier this year, both fixed/replaced., both relatively new and am thinking I might have had a voltage spike since it was about same time. Since I have 240 and 110 going to the equipment, would I need two regulators? I found this one on Amazon. Any others folk recommend?

 
The surge protector connects to the two hot legs in the panel and dumps any surge to ground. That covers both 240V that takes power from both hot legs or 120V that takes power from one hot leg.

Does a surge protector eat up a breaker spot or does it connect differently somehow?

When installed properly in a panel, it will need a double-pole breaker rated at 20A. That will take up 2 panel slots. The SPD must be DIRECTLY connected to the bus bars through a breaker in order to properly protect equipment. It cannot be wired in parallel with other devices.

How easy is it to change? Do you just keep a spare on hand and replace in the event it fails after protecting a surge?

Well, the hope is you don’t replace them often. Replacing them is typically the same as the installation process so as long you’re comfortable with electrical panel work, it’s not hard.
 
I'm not at all comfortable working near the breaker panel! I will change a lightswitch or power outlet, but when those wires get thicker, I get to calling in help. Any idea what a set up like this might run?
 
An SPD runs about a hundred bucks (but an electrician will charge a markup) and you’re looking at a minimum of an hours labor charge. Most electricians I know will charge A LOT for that hour and easily double the cost of doing it yourself. You might see if you can find a handyman with electrical experience that could do it cheaper. It’s not hard work, took me about an hour and I had to run to the hardware store, so it’s really not something you need an electrician for. But you’ll have to price out the labor where you are.

You could take a look at the following, it installs just like a breaker (placed at the first breaker position).


Those snap on style SPDs are fairly low power. The one listed is only good to an 18kA surge. The SquareD HEPD80 ones are rated to four times that capacity (80kA). Warranty is also an important factor as some SPD manufacturers will warranty the equipment the SPD is connected to.
