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?

Ask The Experts

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   54

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?

Ask The Experts

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

E&S Grounding Solutions   Jan 3, 2020   0   52

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?

Ask The Experts

How Does One Lightning Strike Kill Multiple Animals?

E&S Grounding Solutions   Nov 6, 2019   0   93

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.
