Default 28-600 Clarification

Good day gents I'm typing from my phone so I'm unable to copy and and paste quickly 28-600(1)(2)(3). From reading it it sounds as if the rules are contradicting themselves so some clarification would be greatlt appreciated. In the rules it make it sound that if you had any equipment using a motor like say a heavy duty belt sander that is single phase 220V that it would have to have its own disconnecting means but then in the other rules it makes it sound as if you can have multiple devices running from one disconnect. Reason I bring this up is because I ran into a situation last week.

Situation is as follows, in the carpentry shop there is a 30A/240V fused disconnect and when I opened it found that on the load side of the lug there were 3 wires in it going off to 3 different devices. I'm pretty sure off the bat that this is a violation as lugs are by default to only have 1 wire under it unless the lug states it can have multiple wires. Anyways to get on with the story an electrician i know decided to hook up a new installation (heavy duty belt sander) under the same lug so now this disconnect is now in charge of being a means of disconnecting 4 devices. I called him out for doing it and he got super pissed off at me.

So seeing how the wording of 26-800 confuses me as it sounds like you can run multiple devices off a single disconnect as long as the disconnect say had 1 wire coming off the lug into a junction box which would then be marretted and go off to its device or am i out to lunch. The way I feel is that each device should have its own disconnecting means that way if you had to do work on a device you're not shutting down all the other devices connected to the one disconnect.

As always appreciate your guy's quick and knowledgeable responses

You can have more than one motor fed from a single branch circuit but there are conditions. See 28-206.

Awesome. Did a little more digging and 28-208(c) seems to apply more to me if i wanted to run all motors off one circuit. 150% largest fla plus remaining fla's. Thanks for making me dig a bit more ^.^
