Long time lurker first time poster. I am a controls engineer with a heavy background in programming and automation. My question is this:
We have a machine that has been requested to keep the 24VDC "UP" during maintenance periods. The team wants to put a PDB inside the main panel PRIOR to the main disconnect. This PDB will feed the 24vdc psu with 480. The idea being we need another machine to monitor the safety circuit on this equipment during maintenance intervention via PLC and other networking devices.
This project just seems like a bad idea, I do not know the NEC code that well. What are you guys thoughts?
