    More than one wire under a screw terminal

    Type MC-HL cable has 3 ground wires. Do you think this is a code violation? Or is it ok to twist together and land.

    Not familiar with the cable in question, but something tells me the three together must be used as one EGC - so that sort of makes it one conductor? Kind of like the concentric bare conductor in SE cable or other similar cables.

    They appear to be smaller then the insulated conductors on what looks to be less then 10 AWG, but not really certain what thickness of insulation is either.

    I'm picky about the control cabinets I build.

    This one just confirms how good of a job I do.

    As far as more than one conductor under a screw, it's fine on the EGC's to do that as long as the terminal is actually rated for such.

    Thats a 12/3 Okonite CLX 546-31-3453 with 3 #16 grounds. However if you look closely, you can see what appears to be a single #16 from the ground strip to the TB-480V ground. That wire should be up sized to a #12 and landed under its own termin.

    OT, but why is H-300X L3 (blue wire) tucked back inside the Panduit?

    I don't think the grounding terminal blocks on the denrail are rated for more than one conductor but I may be wrong on that.

    A single phase 480v load would be my guess.
