WOW! I didn't mean to open up an old gapping wound here. I saw that picture in EC&M awhile back. I saw a similar installation yesterday, and honestly, it looked like crap. Having said that, I have done this sort of application before and will continue to do it (not exactly like the picture) until either NEMA, UL, NFPA or any other governing body addresses this issue and makes it SPECIFICALLY clear as to the proper techniques and uses of certain fittings so we can get this cleared up. It's a matter of interpretation by the AHJ on whether to accept this or not. 110.3(b) is clear but vague. Last time I checked there were no instructions with a box of fittings as to what is the proper procedure for installing the product, but I have a feeling its coming. IMHO, a coupling is used to couple, a connector is used to connect, an adapter is used to adapt. Do you connect two pieces of pipe together or do you couple them together? Do you couple a conduit to a box or conduit body, or do you connect it? Adapter is what we use to make things work.
