Easy installation. Working great

This Universal HVAC Surge Protective Device seems to be of high quality due to the material used and the look. It was extremely easy to install and securely tight in place not letting a drop of water to enter. I feel a lot more secured knowing that my AC unit is well protected.

After some recent storms, I'm adding the AG3000 for my external HVAC equipment as well. Super easy install, there are a ton of guides online for Type 1 and 2 installs. I also added the PS3000 to my outdoor pool equipment, unfortunately AFTER a lightning strike took out my Pentair Intellicenter the week after it was installed. Every pool builder should be installing this by default, and if you own a pool/spa, especially with an outdoor electrical box/disconnect, you need this. If you are unsure, contact your pool builder and/or a licensed electrician.

This really works this is a great product that I would recommend anyone to purchase for your Central AC unit. This will really help you to save money.

Initially, I did not notice that the leads were aluminum wire not copper. That concerned me because my house wiring is copper. I was able to locate connectors that would accept aluminum to copper connections and used those which relieved my dissimilar metal concerns. The supplied leads were very long, for my situation and could be trimmed to a proper length. This surge protector shipped fast and was easy to install once I found acceptable wire connectors.

This item arrived when expected and was new in the box. Intermatic has a long history of producing surge protection devices (SPD). This device is made of two 150V clamping devices in a single NEMA 4x box. It's designed to be connected to two hot legs (standard residential split phase) and ground. It is not designed to provide neutral line protection as most residential condenser units don't have a neutral anyway. This is not an EMF or noise filter, just a spike/surge protector.One reason I got this unit is because it is listed with the new standards (3rd edition) and it is listed as a type 1 and type 2 device. It also has 10 Ga. wire rather than the little 14 Ga. wire that others use. The specs are not the highest, but it's hard to directly compare 3rd edition standards with earlier SPD/TVSS ratings. Other comparable devices are the Supco SCM150 and the ICM516 units.My HVAC condenser is not a computerized heat pump but it still has advanced controllers that cost hundreds to replace if they blow up. So it's worth doing something simple to try and help reduce any surges/spikes from damaging my condenser. Intermatic also includes a 3-year $7500 connected equipment warranty (which may be as hard to prove and collect on as others).It was easy to install at the condenser disconnect (it installs in any position in a standard knock out, I picked left side). It comes with a rubber gasket for the lock nut to prevent water from getting in. It has a simple single green LED that tells you there is power and it's "working". It's hard to truly test these units as I'm not in an area that takes a lot of hits. If this unit blows up (or fails in some way) and my HVAC system is still running then I'll say it works and get a replacement, but until there is a problem I'll have to assume it's doing the job...UPDATE: Just short of 2 years the green light went out. This means the unit has failed in some way and is no longer offering full protection. I went to Intermatic's web site, filled out some forms, got an email, FAXed them the information and amazon receipt without talking to a person. I had a new unit for free in about a week. No equipment damage noted.

So far so good we’ve only had one bad storm so far and my AC did not shut off. Let’s hope I don’t have a power surge, but my green light is still flashing.
