Question about what is considered control wiring…My lead JW is using 14 AWG to control the coil for a starter and heaters of a blower reel/exhaust in a mechanic shop. Basically it’s an interlock to make sure fan is on when the exhaust hose is being used on a running car in the shop. Since this was added after motor disco and reel switches were wired…He’s mounting the starters and piping over to the reel circuit using 14 gauge even though they are fed with 2.0 amp circuit, he says they are control circuits. Is this code compliment? I feel like control wiring is actually for factory assembled panels…but I don’t have much/if any experience with them.

Thanks in advance,
