An example of dealing with "partitioning" between 600V and non-600V compartments are touchplate controls, which fit in a ½-inch KO in the dividing wall.
http://www.touchplate.com http://www.touchplate.com/relays.html Fairly sure that they are also intended to be mounted in a KO in a ~4-square box with the 24-volt side bellwire leads “floating.”
Is the other guy's stuff listed/labeled? If it isn't, raise heck. If they are, the instructions packed with his stuff should have unambiguous, code-compliant installation methods.
