Selecting a proper type of cable

[rustydud]

Hello everyone,

Looking to spec cable for a project.

I originally thought to use TC cable. But based on NEC 2017, I cannot use TC cable. Based on the NEC 2014, I could argue that TC cable could be used based on 336.10 (7); however, NEC 2017 has no such clause.
I cannot use flexible cords (NEC Article 400) because this is a permanent installation and therefore not permitted.
I cannot use MC cable because I've heard it is relatively expensive, and because I am told it is not allowed.

Here are my requirements:

· Application: in free air, secured with heavy-duty harness clips and tie wraps. The cable will be protected from physical damage by a sheet metal cover.
· Rated at 60 degrees C minimum
· Rated for wet environments including dripping rainwater
· Excellent UV/sunlight resistance
· Abrasion and chemical resistant
· Power and Conductors as stated below:​

Power?​	Conductors? (# and AWG)​
24VAC​	2-#18AWG+GND​
4-20mA​	2-#18AWG​
Modbus communications​	2-#18AWG​
460VAC 3-phase​	3-#10AWG+GND​
120VAC 1-phase​	2-#12AWG+GND​
120VAC 1-phase​	2-#16AWG+GND​

Are there any good "guides" online to help someone like myself narrow down what type of cable to use?

Any thoughts on what I could use?

Thanks!

Is this a carry over from your other thread (http://forums.mikeholt.com/showthread.php?t=187708)?

If so, just run the 20' of pre-wired cable/cord in conduit and be done with it.
