Making connections in Condulet ? Wiring thru machine ?

[Besoeker]

A little off topic, but I've never seen black electrical conduit.

It used to be common here but I haven't seen it used in donkey's years

A little off topic, but I've never seen black electrical conduit. I've done no research, but I'd guess that 99% is galvanized, the remaining 1% is divided among stainless, aluminum, and other. I believe it is made in brass and copper but have not personally seen it. Recognize I'm not an electrician, rather a (now retired) electrohydraulic guy whose involvement is in design, specification and commissioning.

We use black pipe for FLUID conduits. Galvanized is "bad" because the internal galvanizing tends to come loose and plug orifices and interfere in other portions of operations.

We have some plastic coated rigid that's black where I work. It's a wet environment. I understand it wasn't cheap.

We have an application of a sensor where we make the connection inside a C-Fitting (form 7 condulet ).

Is making connections inside the C box addressed in the NFPA 70 or 79 ?

What about running wires thru machine body, such as square tubing etc that is part of the machine structure ?

Sure you can make up connections inside a Condulet, and it is a common practice on older machines. Newer machines use basket tray mostly.
I will also point out that cabling is commonly attached to all kinds of stuff; unistrut, machine structural elements etc. Connections are usually
made with connectors or are made up in boxes on terminals. Offhand I don't know all the legalities but machine manufacturers run cabling all
kinds of ways so I assume it is legit, including running through tubing as mentioned.

What is condulet as opposed to conduit?
