Everything that Jimmy has said and more.
Inspectors need to see the breakers, the wires that they feed and the color codes used. The terminals must be rated for current that exceeds the protected current for that branch (i.e. rated for 40 amps minimum when branch is protected by a 40 amp breaker). You may need to show data for those terminals during inspection.
From 2015 rules (unlikely to change much)
R40 All non-SIGNAL LEVEL wiring with a constant polarity (i.e., except for outputs of relay modules, motor controllers, or sensors) shall be color-coded along their entire length (from the manufacturer) as follows:
A. Red, yellow, white, brown, or black-with-stripe on the positive (e.g. +24VDC, +12VDC, +5VDC, etc.) connections
B. Black or blue for the common or negative side (-) of the connections.
I agree with Gary that heat is a bad thing especially when under the RoboRio.
