Low power on shop electrical circuit.

I enjoyed and was pleasantly surprised at the interest and good questions above. Hey n g and ng bonding is confusing even to some professionals let alone non electricians or engineers it took me study practice and nec seminars to grasp it and I enjoy helping but again it can’t be explained to non sparkies here in a paragraph lol

Thanks to all who took part we pretty well beat the old n g bonding, reasons for a single ng bond and the difference in grounding g versus bonding horse to death lol

Thanks to those who took tine to look up and post info and for all the good questions people posted !!!

God bless yall

God bless you as well.
 
bond ALL metal stuff in a building to provide a path from that metal to the ground rod
This is not what "bond" means in the context of neutral and ground bonding. Yes, all the metal parts of electrical enclosures, conduit, etc, must be connected together to work properly. This is NOT the same as bonding the neutral and ground.

This is ensuring that all that metal is connected together with the "Equipment Grounding Conductor"; the green/yellow, or green, or bare wire. All this is tied to the ground rods at where ever they are. There is only one "BOND" and that is in a specific location depending on how your wiring is done. Terminology is important here.
 
Keep going……no one has yet convinced the other that he is smartest guy & never will, no matter the volume of words .

X2 and Dutto. Exactly !!!! Terms of art are I indeed important. Good job

EGC,,, Grounding,,,Bonding,,,Single NG Bond, snd reasons why can be complicated and confusing and hard to explain to non electricians for darn sure lol

PS Having all the metal and case/frames and junction boxes connected to the EGC serves the purpose of fault current return path to trip the breaker and clear the fault.

However it also keeps items at the same potential and csn help with hv surges and spikes and lightning. Why ????

Same reason neutrals are earth grounded. Note the EG buss is bonded to neutral and also thereby connected to the grounding electrode system such as driven ground rods

IE connecting to the EGC serves two purposes Alls well the nec works Hv surges lightning as well as fault current return path yay



Take care, good post

Yep. Lightning and someone sticking a monkey wrench inside your panel. When a rat chews through your wiring, you do your best James Cagney impression, "You Dirty Rat!!".
