EATON CHSPT2ULTRA Ultimate Surge Protection 3rd Edition, 2.38 Length, 5.25 Width 7.5 Height

It works, wiring to short

So Far So Good. I hope I dont have the need to see it it works

Well, it installed easily. However I hope I never have to follow up on how it actually works. But after replacing three RV, some flooring where a water line melted when the lightning strike went to ground, two ROKUs, cable modem and two computer power supplies, Im hoping it will work as expected.

Love it - every house should have one!!! Yes, its work or additional cost to install, but had few Insteon home automation switches being damaged during thunderstorm before installation. Had for couple of years, no problems anymore.

I got the Eaton Ultra SPD (Surge Protection Device) and overall the installation was pretty easy and I did use a 50A 2-pole breaker per the instructions!

Pros: New house in FL, lots of lightning, etc., in the rainy season!

I installed this Whole House Surge Protector in November 2013 and so far all is well. Both lights are still green. A Whole House Surge protector should never be a stand-alone solution and heres why: This EATON CHSPT2ULTRA will pass 600 volts of surge energy into the house before it begins to divert the surge to the EARTH ground. But the manufacture states that you need to add 25 Volts to that number for each inch of wiring used. Since a typical installation can be from 12 to 18 inches, then the total amount of voltage being passed into the house before the SPD turns on would be from 900 to 1050 Volts. The IEEE recommends that this device be used in a layer approach, that is use additional Type 3 SPDs throughout your house. The IEEE also states that some 20% of surges originate outside the home as a result of power company switching equipment, trees falling onto overhead power-lines or lightning induced onto overhead or buried power lines. Thats where this unit helps because once the voltage reaches between 900 and 1050 volts the remaining surge energy will be diverted to the EARTH ground. The IEEE also states that some 80% of surges originate within the home as a result of motors (refrigerators, freezers, air conditioners, vacuum cleaners, furnaces, washing machines, clothes dryers, blenders, mixers, power tools, etc ...) and/or ignition devices (electric stove tops, water heaters, furnaces) cycling on/off. From the side panel on the CHSPT2ULTRA Where do surges come from (1) Lightning, (2) Utility disturbances, (3) Home Appliances turning on/off. Since I have a solar array on the roof I also have a Midnight Solar SPD on the Solar electrical junction box ahead of the mains electrical panel (those are the other electrical boxes on the side of the house)

There are easy to follow instructions on Youtube. Not a lot of experience is needed but you should have some familiarity with basic wiring methods.

Primary issue - Eaton requires a 2 pole 50 amp breaker. Minimum wire size for that breaker is 6 awg. The 14 awg on the surge protector are too small unless you modify them , which voids the warranty. . Secondary issues - The two hot leg wires are a shade under 15 inches. The neutral and ground wire are 16.5 inches. This is not published in the specifications. That’s about a inch less than I needed for the hot wires. Measure your system carefully. If your panel is in a stud bay instead of on the wall, especially if it’s a tall panel, you may not be able to use this item

Opened this device to see what it was comprised of, and am pleasantly surprised with the build quality. The primary mechanism to protect your home from power surges are 6 metal oxide varistors (MOVs) per leg, 12 MOVs in total. The MOVs are Sincera MOV-20D241K. They are rated for 150V, meaning that any voltages over 150V are shunted to ground/neutral, protecting everything on both legs of your panel. Their maximum clamping voltage is 400V. (I am not an electrical design engineer, but this is my understanding of these values having done some amateur electronics projects) As I understand surge suppression, while this will not protect from direct lightening strikes, it will protect you from spikes as appliances turn on/off and some amount of transient voltages that are induced into wiring from NEARBY lightning strikes. There is not much any homeowner can do to protect from a direct lightning other than having lightning rods with great grounding. The housing is very sturdy plastic and is outdoor rated. The circuit board is silicone dipped to protect it from moisture and the housing has rubber gaskets on the screws holding the halves together. If installing outside I would install it under a circuit box to provide some protection from direct rain.
