I am planning the wiring of an EMI chamber.  We need 28VDC up to 30A in addition to the AC power.  There will be an ungrounded conductor (+28), a grounded conductor, and an equipment grounding conductor.  I want to have the receptacles along the base in divided metal raceway (G-4000).  Does someone have a suggestion for a code compliant receptacle for this application?   This is to be used for testing purposes.  Other than the raceway wiring everything plugged in is temporary in nature.  It can be a straight blade device, it doesn't need to lock.
