Re: Appliance grounding- Old three wire circuit
On a semi-related subject, last year, I installed an ATS where I had to place a main disconnect ahead of the ATS. I added a grounding bus to the panel and relocated all the EGC's to it, and removed the panel bond.
The range and dryer were wired with aluminum SE cable, as was common practice then, and they were run throug a part of the house that was impossible to rewire through: a breezeway that was later enclosed.
The "attic" space above the converted reezeway was not accessible from either the garage (where the panel was), nor the house, because that space was single-story height and the rest of the house was two floors.
I spoke with the inspector beforrhand, and he agreed with my suggestion that I wrap the SE cables' bare conductors with white tape from the sheath to the neutral bus, and not the grounding bus.
Our combined reasoning was that using the neutral for grounding was better than using the EGC as a neutral, since both appliances have line-to-neutral loads, like motors, timers, lights, etc.
It was a pleasure collaborating with "the other side" instead of clashing. I've never really had any problem with any inspector because we're always respectful, and it always turns out that one of us or the other is correct.
