I was on an inspector forum and one inspector asked the forum if an electrician was in violation because he had not ran a ground in with his hot and neutral in a EMT conduit leaving the panel.no one asked what kind of KO it left through or if it had a bonding bushing. . can EMT be the ground?all replies said the EMT was acceptable for grounding

It causes me alarm to read that an inspector would say that. Then again there are local amendments in places that deviate from the NEC in large degree so maybe that is what he is thinking about.

Be careful just because the nec says it is does not mean you always can. For instance if the electrical engineer specs on plans that an equipment grounding conductor must be used then you must follow the accepted plan.

Perhaps, but can a municipal electrical inspector police the electrician's compliance with the contract drawings and specifications? I don't think so.

Absolutely they can. If the plans have gone thru the inspections dept and have been accepted then they are accepted as written. Unless the engineer asks for the change to be made you must install the equipment grounding conductor.

Legally the inspector is required to assure the compliance with the approved plans and specifications. And the contractor is obligated to construct to them.

In reality, if the contractor does not point out variances from the code in the plans and specs to the inspector, most of them are too over tasked to catch the requirements that vary from code minimums.

The scary part is even if the inspector misses a call out for most of the job and catches it when you are nearly buttoned up and off the job, they can make you go back and comply.

In most states the Designer who sealed the document is responsible for assuring compliance.

Thanks, I thought I had researched this before. Obviously I'm mistaken, I do remember plenty of times I looked up and the cunduits weren't connected anymore. So i started putting the sized ground I need in the conduit..guess I need to start making payments to my boss for all the ground wire I ve wasted.

its not a waist at all, more security. the company i work for, we dont pull a ground unless speced, its kind of sketchey because your relying on everyone tightening there fittings which some people have a hard time doing.so the suplementary bond wire is a good thing.
