400KCMIL copper in control cabinet, would not recommend.

No offense y’all but cabinet codes and industrial codes are not the same everywhere. Amperage is based off full load. There are controls and high leg devices in that cabinet.

If you’re not an engineer or have the equivalent training to build cabinets; automation integrator etc, shouldn’t you not make statements like that? “Not recommended” means what exactly? Shouldn’t the mods be handling this?

I’m not saying it’s correct and that depends where in the world this picture was taken. Where I am from - there is absolutely nothing wrong with this and have seen it thousands of times in thousands of cabinets all over the Midwest.

I would guess a maintenance person built this cabinet - but 480 and controls in the same cabinet is extremely common and as long as the devices in the circuit and the size of the cabinet is correct minus the bend in the wire there really isn’t anything else “wrong” with this layout.

Power supply coming in needs to handle all devices at FLA, odds of all devices at FLA at the same time is almost zero.

I am not an electrician- I am a plant engineer turned Cap Asset Mgr and I am throwing my point of view out. Some of y’all make statements that are awfully misleading. Go ahead. Roast me. Lol
