I understand what you are saying luckyshadow, but I have already appealed it to the engineer and he has said do it his way. At the end of the job I will have to sign the plans stating I did it per the plans. So I either need to keep confronting the EE, or lie about what I did on the job.

I am thinking about doing the 3/4" run + pulling a #6 ground in each 2". I'll be pushing the wire fill by 2 mm^2, but at least I'll know if there is a ground fault the breaker will trip. And I don't think its wrong for me to exceed what the plans call out.

My other option is to walk the inspector right by and have him issue a correction [Linked Image]
