Location is in Michigan. Gauge for the cable along the whole run will be 12g. The installation includes EMT conduit, but 358.30 doesn't exclude installation of boxes in between structural members; only that they're securely fastened following the required intervals. The structural members are currently designed at a center to center spacing of just under 7 ft. I've referenced 2014 NEC Handbook related to this inquiry.

Feed the NM cable into a junction box and connect the conductors with appropriate connectors. The NM ground would connect to the ground wire already in the box, if any, as well as to the box itself. The NM .
You'll need to make sure your EMT fittings are rated for being threaded into a hub. The thing with weatherproof cast boxes (Bell boxes) is that they have cast-in threaded hubs in them instead of ordinary knockouts, so that water can be kept out reliably. However, UL historically did not test EMT fittings for use with threaded hubs, only locknuts, and as a result, . Orienting the boxes vertically for a horizontal entry seems elegant, but it's a total fail for buildability. Instead, simply nail in a "crossbar" 2x4 and mount the box horizontally face-down with about a 1/4" inset so the pipes go into the side of the box perfectly. Let's review some other EMT 101 stuff.

I am planning to pull three sets of four conductors (3 AWG wire) through 2" EMT conduit for a 30' length that is common to all three sets of wires, and then branch off at a listed metal junction box (10"x10"x4") to three 1 1/4" EMT conduits. I am in a "discussion" with my boss about how often you have to put a j box in a run of emt. I know that every 360 degrees you have to have a j box. He is telling me every 100'.

Metal conduit and junction boxes outside MUST be grounded for the same reason even low voltage cable must be, it gives static from things like wind a place to go instead of building up and creating a lightning rod (which is a misnomer as a real lightning rod prevents the strike by giving the static an earth/ground path that’s safe).How can I add a junction box here without pulling the wires out from the run? The conduit body is for 3/4” EMT and was used in-properly as a transition from 1/2”EMT ( both the left and top conduit pieces are 1/2”EMT) to a 3/4” EMT run. .
