can anyone find faults in this solution?
All I did ask here if anyone sees a code issue with this.
The code issue was decided right off, everyone agreed that useing EMT for an EGC was legal.
There are possible faults to the solution or most of the contractors in this country are idiots. There certainly are a lot of grounds pulled and it's not just to support the cable manufacturers. I think a lot of grounds are pulled because contractors understand that conduit isn't always run correctly to provide an acceptable ground path.
You did the job and if it was approved by the local authorities then that's all you need.
There are lots of people that may read these post in the future if they are faced with the same problem. It's good for them to understand there are many different opinions on the subject. Once they read the different opinions it will be up to them to make up their own mind on what they need to do.
You will get many different opinions on which brand of toilet paper is best so don't expect to get some sort of unanimous consensus on EMT as a ground path.
The thing to remember about the NEC is that if it were perfect it wouldn't need to be revised every three years. EMT is legal as a EGC at the present but it may not be in the future for some of the same reasons pointed out on this very forum. On the other hand it may still be legal a hundred years from now because it's considered safe enough.
We haven't all been brainwashed to the point that that we agree with everything we see written in a book.
