I'm currently attempting to put together a panel build just like Johnodon's build on here (PJ diagram Auberin-wiring1-a4-5500w-BIAB-30d6.jpg). I've bought almost all the parts and then I was looking at the diagram and realized my flush mount outlet for the element is not the same as the one in the diagram picture. I bought the only 3 wire range cord I could get at Home Depot and it was also linked on PJ's brewery parts spreadsheet (http://www.homedepot.com/h_d1/N-5yc1v/R-202214665/h_d2/ProductDisplay?langId=-1&storeId=10051&catalogId=10053#.UKryAmf_KSo
). I also bought the flush mount outlet to match it.
However, the plug has the L shaped prong on the bottom and the outlet says non-grounding. The 3rd prong is meant to be connected to a neutral. PJs diagram shows connecting the 3rd prong to ground, not neutral obviously. I'm wondering, though, does it matter if I connect that neutral prong to ground anyway? Is there something in the plug construction that would prevent it from working with a ground connection instead of a neutral or is it not sized appropriately for ground? I'd like to be safe, so if it means eating the outlet that's fine. But if it's safe to use I'd rather do that.
