In a house, I have 2 hots, a ground, but NO neutral ran where I would like to hook up a 240V/120V gas/electric range. I am aware that one could connect the appliance neutral to the ground and it would work, however that could be potentially dangerous/deadly. In my situation it would be extremely difficult and expensive to run a neutral back to the circuit breaker, so I was wondering if it would be OK to wire the appliance neutral to the ground if one was to add an additional ground wire that connects the appliance ground to a new grounding rod outside? Thank you.
