Circuit board X-ray machine calls for specs of a 30A 208V single phase circuit.
Also calls out an additional #2 AWG insulated copper stranded, from the frame of the machine to the panel for high freq. ground.
330.3(B) says all equipment grounding conductors and bonding conductors shall be installed in the same raceway. However the machine comes with a prewired 30A twistlock plug.(standard nema plug) The #2 ground is additional to the normal #10 eq. ground.
I ran the #2 external to the emt, (tywrapped to it) from the frame of the machine back to the panel.
Did I make a boo-boo?
How do you handle this?
Thx..
