I guess not.

Even then, many surges occur before anyone knows they are coming. Proven protection is one that is also needed for other appliances such as the refrigerator, recharging mobile phone, clocks, and the air conditioner. If you or your machine needs protection, then so does everything else in the house. Disconnecting is only good for a lesser number of transients.

Either that current is inside the house hunting for humans and appliances. Or it is connected to earth BEFORE entering a building. Once inside, then nothing can avert a destructive hunt. If connected outside, then no human or appliance is at risk. Even a heavy duty computer protector does not claim to protect from this type of transient. For over 100 years, the proven solution is proper earthing of a 'whole house' protector. Unlike disconnecting, it is also reliable.

After I had my whole house NG generator installed after Hurricane Katrina I also had Mississippi Power Company install some kind of a device on my outside service which they told me would give me better grounding protection. I don't know what it is but they recommended it and it didn't cost me anything. I'm not a licensed electrician nor am I an electrical engineer but I do know how to use their service; running my central A.C. wide open today because it's hot out.

How surge protection works was taught in elementary school science. How did Franklin stop lightning from connecting to earth destructively via church steeples? A lightning rod connects that current harmlessly to earthing electrodes.

How do you stop lightning from connecting to earth destructively via household appliances? A wire or 'whole house' protector connects that current harmlessly to earthing electrodes.

In both cases, the destrutive current never goes inside a building. In all cases, protection is only provided by what absorbs energy - earth ground.
