Review on 💡 Enhanced Siemens QSA2020SPD Circuit Breakers with Advanced Protection Features by Tay Fair

All in all a good surge arrester that is exceptionally easy to install although I strongly advise against ANY homeowner working in their electrical panel. This is a good way to die or get hurt if you are not a qualified electrician. However, you should be aware that this surge protector will not protect against lightning strikes entering a home through a low-voltage coax or data line. Think of the path he's on. If a surge enters your main electrical panel through the service wires, it will have to go through a house-wide surge protector before it gets through the branch circuit breakers, but that's unlikely. "Whole house" is a misnomer because, as I mentioned earlier, this surge arrester, or any other brand, mounted in or attached to the main electrical panel will not protect against lightning strikes through the low voltage line. Additionally, most whole-home surge arresters do not provide adequate lightning protection because they do not typically enter the home through the main electrical panel. The factory recommended setting is 2 digits above the main switch on both sides. (This also applies to other brands that are powered by a separate 2-pole breaker.) It is also known that most surge protector manufacturers do not guarantee "connected" loads, which means almost any connected or hard-wired load (devices, TV , other electronics etc.) .d.). You should also be aware that all manufacturers of whole-house surge arresters recommend "distributing" surge protection strips throughout the house in combination with a whole-house surge arrester. This gives an extra layer of surge protection. Leviton has a nice option that mounts on the outside of the panel and is powered by a separate 2 pole switch. It comes with what appears to be a good guarantee, although I've never had to use it. However, this silencer is definitely more difficult to install than Siemens. The Siemens Whole House Surge Protector we're talking about actually did its job in one of my clients' homes that had a loss of neutral due to a car crashing into a utility pole next door. Both green lights went out and the unit burned out due to high voltage surges on each incoming 120 volt leg. The device smelled badly burnt and was replaced. What most people don't realize is that most surges are caused by "compromised neutrals" and not lightning strikes. They usually come from the energy company side, but you will never get a refund from them. Believe me. My comments are based on personal experience and I've been an electrician for a long time.
