I am reviewing a plan that shows motors in a building that is entirely class I division II being fed from an MCC located in another building.
The motor feeders go directly from the MCC to the motors with only a lockable switch at the MCC (nothing insight of the motors) for a disconnect.
In order to kill all power to this building, you would have to turn off the mains in two separate panels in the building and four switches at the MCC in another building.
The engineer tells me that this is a common industry practice for this type of facility.
Is there a code section that would allow this type of design?
This is a compressed natural gas storage facility, is this a common industry design for this type of project?
