Square D - HOM250PSPD Homeline Whole House Surge Protection Device, 50kA, 120/240V, 1-Phase, No Wiring, Plug-On Neutral

So far I’m giving this a good review. It’s been in now for 2 months and haven’t had any issues. As long as it protects my freezers and coolers it will be well worth the money. Simple to install.

Must have for any whole house application. Easy to install!

cant say on how well it works, but i feel better knowing its in my panel. I like that it does not take up a lot of space in the panel and install is pretty straight forward.- Make sure that everything lines up perfectly when installing. This will break pretty easy. if it doesn't just slide on, double check. I installed my entire panel and over 25 breakers, this was the last thing to add. It is no where near as heavy duty as the breakers, nor is the contacts greased. First one broke and second one i added dielectric grease and worked just fine. pictures are of the first one that broke, you can see the contact pushes up into the housing

Installed easily in my interior subpanel (main panel is exterior, I put another brand and style rated for exterior use on that one) in the closest breaker position to the main feed and now we see how it performs… great value up front.

This is pitched as a whole house surge protector you simply plug into your Square D Homeline panel.It is a straightforward install, however note a couple of things:1. The required neutral connection is done (for installation convenience) via a clip on underside of unit that clips over the neutral bus bar adjacent to break mounts - normally this kind of unit would use a free white neutral wire that one manually connects to neutral bus bar. This means you must have the neutral bus bar extending to the open breaker slots you plan to use. Mine did not, so I had to reshuffle breakers on panel to free up open slots further up that were adjacent to the neutral bus bar.2. I also had to relocate the existing neutral wires screwed into bus bar right by the free breaker slots I wanted to use, and had to remove the wire securing screws in the neutral bus bar there, as the neutral clip on the back of the unit will not fit over any wires or screws.3. There are two grooves on back of the unit, one for neutral clip mentioned above, the other is notched to fit over the plastic mount on panel. This plastic mount on my panel had a different notch pattern and had to be ‘modified’ so the unit properly clicked in place. Basically I twisted off a couple of the plastic notches. Given the neutral clip is quite secure, the unit is securely mounted even with this modification.** Note please ensure you switch off panel power when installing this (well, really of course you always should) - for real this time - do not be lazy. You have to fiddle around close to live circuits and it not a happy ending to take shortcuts.Before installing or purchasing take a careful look at the unit to ensure you are clear how it will fit in your panel. I am just recounting my experience, not offering expert advice you should follow.

It's exactly what I ordered and it arrived quickly. It hasn't been installed yet, I'm on a waiting list with the electrician. I'll resubmit another post after it's connected and operational.

Very nice quality.

What more can I say. It was a good price on the part I needed. Of course it was easy to install, I paid someone to do it for me. You want to make sure these things are done properly after all. :)
