Conduit bonding with class 3 circuits

[Isaiah]

If a class 3 circuit is ran in a rigid galvanized steel conduit does the conduit still have to be bonded? The vendor supplied cable is being ran to (very low current) proximity switches in RGS conduit, which is also vendor supplied —But it’s not bonded.

Is this an Article 725 or Chapter 5 class 3 circuit?
In either case we see very few Class 3 circuit questions

Further review shows it to be a 24VDC circuit with 30mA.

Based on 250.162 I would say no unless specifically required by a Code section relative to your installation.

I have never seen a Class 3 circuit. The RMC requirement was why I thought it was a chapter 5 application
