The point of interconnecting electrodes is to create equipotential. Accomplished by interconnecting wires that are buried. Then safety code says how deep and how much thicker that wire must be.

That rod (electrode) must first meet human safety requirements. At minimum, it must be at least 8 feet deep. Usually, electricians install multiple rods rather than buy a machine to measure ground...

That prong is a safety ground. Surge protection is about something completely different - earth ground. That protector must make a connection to earth that is as short as possible. A connection...

A failed $20 protector means it did no protection. An appliance protected itself while the protector disconnected as fast as possible from the surge. Left the surge connected to the appliance. If...

If internally generated surges were destructive, then we are replacing dimmer switches, GFCIs, and digital clocks daily. Due to superior protection already existing in all appliances, those...

Protection already inside a computer is typically superior to anything inside a power strip. A tiny surge, too small to overwhelm protection inside every computer, can destroy a grossly undersized...

Lightning is an electrical connection from the cloud to earthborne charges maybe five miles away. An electrically shortest path is maybe three miles down to earth. And four mile through earth. ...

Technicians are only taught what they need to know to do the work. An electrician, for example, would not know anything about wire impedance because his job is mostly about installing wires safely....

Because it is called a protector means it does something useful? Defined was what does the protection:
“ low impedance (ie 'less than 10 feet') to single point ground. “

How does that...

Codes define human safety; not transistor safety. A protector is about protecting appliances - not humans.

Appreciate what does protection. Not any protector. Protection means hundreds of...
