Best Arc Fault Circuit Breakers
By installing this Siemens circuit breaker and surge protective device (SPD) in the load center of your home, surge protection is provided for all branch circuits. Surge Protective Devices To effectively surge protect your appliances and other sensitive electronic equipment, you need to stop surges before they get into your home and also control surges generated inside your home. Large surges can damage equipment by "burning up" the internal components of your sensitive electronic equipment and appliances. The only way to surge protect microelectronic based appliances is through the application of an incoming service entrance surge protector like a Siemens SPD. QSA2020SPD Specifications Amperage. 20 amps. Number of Poles. Two 1-pole circuit breakers. Initial Clamping Level. 240 volts. Transient Energy Rating. 360 Joules line-to-neutral. 720 Joules line-to-line. Transient Suppression. 500 volts peak, line-to-neutral. Voltage Rating. 1000 volts peak, line-to-line. Peak Current Rating (impulse). 40,000 amperes. Discharge Voltage Characteristic. @ 1,500A, 600 volts. @ 5,000A, 800 volts. (both line-to-neutral). Discharge Current Withstand Rating. 10,000 amperes (line-to-neutral). Circuit Breaker Interrupting Rating. 10,000A, 120/240V AC. Listings/Certifications. UL, CSA; meets UL 1449 3rd Edition. Takes up the space of two standard single pole breakers, but also includes two single pole breakers.

Find Best Price at Amazon"After removing the panel cover, I first turned off two 20 amp breakers, disconnected the wire from each of them and removed the breakers."
"I am an electrician and have started installing whole house surge suppression for customers."
"Note: You will need two 20 Amp circuits next to each other for this product (or relocate them to be next to each other). You should install one of these per subpanel."
"Simple to install if you have some electrical know how, provides a measure of surge protection to your house."
"Bought this unit for ease of install and because of built in single pole breakers. A better set-up as opposed to using a generic surge unit that usually needs 2 dedicated single pole breakers to access both mains."
"I have installed whole house surge protectors in previous houses and these Siemens units were much easier because they mount directly into the panel and you don't lose any breaker slots."
"Make sure you know what you are doing though - working with your power mains is not a good idea ever if you do not know what to look out for. Make the wire as short as possible, strip it, attach to bus bar, pop it in an empty, hook it up to a couple circuits and you're done."
"This functions both as a surge protector and two independent 20 amp circuits."

"Great circuit breaker."
"I have a 1500 watt power invertor in my truck and I had installed a 150 amp breaker for it."
"Much safer on you the individual, and for the vehicle since you won't have to disconnect battery terminals and risk shock."
"The posts are 1/4", so use big eye lugs...plenty of post length to properly connect big cables...if you have 1/4" eye lugs for them. I ran over 90-amps through it, without any heat or threat of tripping...accidentally had a short (big shorts make BIG flashes!"
"I kept having intermittent problems which I finally traced to the fuse holder & fuses. I think the heating and cooling cycles under the car's hood made the fuse detach internally so while they looked OK, they didn't conduct the electricity effectively and resulted in my amp turning off intermittently."
"I chose this Buss breaker to replace an off-brand breaker that became brittle and cracked apart after less than one year."
"Had a lot of problems with my upgraded Merlin charge controller on our toy hauler blowing the fuse to the four Trojan batteries, and after it finally melted the fuse holder, I purchased this circuit breaker, and mounted it right next to the batteries."

"Nice professional grade box."
"Couldn't beat the price, local store want 2x to 3x more on price."
"A little tight but well worth it."
"A little tight, but did the job just perfectly; and at a much lower price than other spa boxes."
"Great product and great service from Amazon...DD."
"Hard to love a metal box, but I do like it."
"The biggest problem with it is that the entry point for this 50 amp service box is on the bottom and so are the outgoing connections (albeit there is a 1" knockout on the side panel but still on the bottom fourth of the panel."
