Square D by Schneider Electric HOM2175SB Homeline SurgeBreaker, Surge Protection Device, 25kA, 120/240V, 1-Phase, 3-Wire

I live in an area where there are frequent power line glitches. Not full blackouts that last several seconds to hours, but dips and interruptions just long enough to trigger my UPS devices. These glitches seem to be the most potentially damaging to electronic devices, especially devices having inadequate internal surge protection. I already have a whole-house surge protector in my house distribution panel, and bought this device for my remote workshop that is on a separate power line. Installation is quick and simple as it mounts in any breaker panel position just like a 240 volt circuit breaker, and requires only the white wire to be connected to ground. The green light provides assurance it is operational when the panel door is opened. Whole house surge protection is essential wherever there is power line chaos and expensive electronic equipment is at risk -- highly recommend.

This was an easy install in a older Homeline panel. I just moved some of the top breakers to get it as close to the inbound lines as possible. It does have a smaller 25kA rating which I assume is a limit of the neutral pig wire connection vs the newer style for clamp on neutral which doubles the rating to 50kA but those only work on HOM Plug-on Neutral panels which are newer.

My electrician told me to buy these. First time they were about $105. I had them sent to the wrong location by mistake so I reordered them to my current location and would return the others for credit when I was back at that other location. When I went to reorder, the price had dropped about $30. I needed three so my mistake worked out to my advantage. Product seem to do what it needs to do and since I have not had any surges that I am aware of, the lights on these units are still green indicating they are protecting from surges.

Very easy to install.

We had a nearby lightning strike create an electrical surge that fried the control circuits in our HVAC system and standby generator. So, I've installed this surge protection in our electrical panel to prevent that from happening again. Rather inexpensive and very easy to install if you're reasonably handy and comfortable working in your electrical panel.

It’s difficult to say how well this works, but it was pretty easy to install. I will say that after installation, I’ve had issues with my pressure washer tripping a GFCI outlet on a different circuit. I haven’t removed it to check if it is the cause, but it is a possible issue.

easy to install. You do not need an electrician.

I installed this in my main panel. Easy peeasy!! Now my whole home has a high lever of surge protection. I had a surge about a month ago that fried my microwave main board. I should have gotten this sooner!!
