What is the Sphere of Influence?

E&S Grounding Solutions   Jan 27, 2021   1   1079

An important concept as to how efficiently grounding electrodes discharge electrons into the earth is called “the zone of influence”, which is sometimes referred to as the “sphere of influence”.

What are the NEC Requirements for Grounding and Bonding Rebar?

E&S Grounding Solutions   Aug 17, 2020   1   1510

Many people are concerned that bonding the steel rebar in concrete may lead to cracking of the concrete due to thermal heating. It is a very counterintuitive concept, but it’s actually the exact opposite.

The NEC calls for use of Ground Fault Protection (GFP) type for circuit breakers for services over 1000A, does this include buildings or just equipment?

E&S Grounding Solutions   Jun 16, 2020   0   1203

Ground Fault Protection systems are very sophisticated devices, often with many variable settings to “Dial-In” the specific requirements needed for your site. Also, the reliability of the GFP systems depends on many factors beyond the proper settings on the device.

Why does my surge protection device say not to use it with power cords?

E&S Grounding Solutions   Jan 3, 2020   0   233

The statement saying not to use with a power cord, has more to do with legal issues than with an electrical issue. However, there is a less than 1% chance that an issue could occur: Take an example of a construction foreman (or forewoman) working at a busy job site.

How Does One Lightning Strike Kill Multiple Animals?

How Does One Lightning Strike Kill Multiple Animals?

E&S Grounding Solutions   Nov 6, 2019   0   499

Herd animals that gather in groups are typically killed not by a direct lightning strike, but by the current flowing through the ground from the strike. What happens is that the lightning strike often hits a tree or the ground near where the animals are gathered and the electrical current then spreads along the surface of the ground and shocks any people or animals in the vicinity of the strike. Electrical current literally goes up one leg and down the other back into the ground. Eventually, the current dissipates as it flows further and further from the strike point.
