My purpose in this thread was to give the OP a clear concise answer to his question that he was not getting, not to debate nor argue with you. I accomplished that.
If you wish to debate electrical theory or code I will be more than happy to do that in the proper forum. This is a DIY site where people come for answers. It is not a forum to show the world how much (or how little) knowledge one possesses.
Well, yes you gave the OP and answer, however, I questioned it and you could not accept that... You assumed in your post (#6) that the OP had a safe ground path which you did not, (and still do not), know.
I am not debating with you... code is not up for debate. My only point (I don't know where you thought it was confusing) was to make sure the OP had a safe electrical connection.
For others in a similar situation here is the reference:
250.30(A)(1) Bonding - Effective Fault Current Path. To provide the low impedance path necessary to clear a ground-fault on a separately derived system, the metal parts of electrical equipment must be bonded together (equipment grounding conductor) and connected to the system grounded conductor (X0 Terminal). The bonding jumper used for this purpose must be sized in accordance with Table 250.66
DANGER: Failure to provide a low impedance ground-fault path (no neutral-to-case bond) for the separately derived system can create a condition where a ground-fault (line-to-case fault) cannot be removed. The result is that all electrical metal parts, as well as the building structure will remain energized with dangerous line voltage if a ground-fault (line-to-case fault) occurs.
I may be beating a dead horse here! but there it is.
