NEC is designed for electrical safety. It's based on the size of the
conductor necessary to permit a breaker to trip when you have a ground
fault.
R56 is designed to improve survivability of lightning strike or other EMP
event. The wires are sized large enough to ensure a low impedance

Depends on if you are grounding for safety and circuit breaker blowing, like
for a receptacle, or grounding for surges etc. They keep trying to convince
the world that a small surge suppressor needs a #6 wire, bu

I personally think some people treat R56 as some sort of gospel that
circuits you normally would use a #14 and #12 ground respectively.

I found some code references saying that an equipment ground wire should be

But Starlink installs don't do this, so apparently we are all doomed.

I found some code references saying that an equipment ground wire should be
either equal in size to the power conductor to the equipment or based on the
amperage of the circuit protection device. For example, a device on a 20A
breaker would use the larger of 12ga or the size of the power conduc
