So I finally get to installing my power cord on my kettle, just like Kal's method. Well I ordered the same cord grips from mcmaster but they don't fit the boxes I got from lowes. But, even if the grips did fit, my power cord is too fat to fit through the cord grip. What should I do? I bought my cords from eBay, the ones with 9' of 10/3 with the locking plug attached that were talked about a while ago. I'm at a loss here so I walked away from it before I smashed it.
I guess I could buy a 3/4 npt tap and drill bit.... That would fix my box, but would I be able to drill out the grip at all?
Edit: I just realized that if I drill out my boxes there won't be any material left for the tap to make threads. Looks like I have to buy and build all new boxes.... FML
