Is there an electrical engineer or industrial electrical contractor on board?

I can’t help you. Sorry.

No problem. When I need NV gear to go high-speed low-drag on hogs I'll hit you up.

I was trolling for a way more retarded reply.

Was I too obvious?

Oh. No, I'm just socially challenged and assumed it was a genuine reply.

Sent some PMs, appreciate you guys even taking the time to look. I've already tried to answer the questions to the best of my ability, and think I'm pretty close, but others have other ideas.

Why don't you share your questions here so we can make this educational for everyone who cares.

These questions are maybe gonna seem a bit crazy, and some of them I believe I have the answers to, but other people have conflicting ideas. A couple of the questions are potentially manufacturing dependent, and I've contacted Support/Engineering with the manufacturer as well; their support lead-time is rather large. Anyway, thanks for taking the time to even look at this.

Thanks for offering to help. My questions specifically pertain to an APC AP8865 PDU, the product page is https://www.apc.com/us/en/product/A...ase-30a-36-c13-6-c19-and-2-nema-520r-outlets/

APC NetShelter Metered Rack PDU, 0U, 8.6kW, 208V, 3 phase, 30A, 36 C13, 6 C19 and 2 NEMA 5-20R outlets - AP8865 | APC USA, Specs relevant to my questions are,

Input voltage: 208V 3-phase
Output voltage: 120V, 208V
Line rated current: 24A
Max line current: 30A
Input current limits: 30A
Maximum input current (phase): 24A UL
Output voltage: 208V AC (line to line), 120V AC (line to neutral)
Maximum output current (phase): 24A UL
Maximum output current (bank): 16A UL
Banks: 3
Overcurrent protection: Three (3) 20A, 2-pole hydraulic-magnetic circuit breakers

I’m only interested in technical specifications, disregarding any environmental, safety or regulatory requirements.

It would be extremely helpful if you could show any/all calculations involved in deriving any mathematical answers.

Question 1: What is the maximum total power (Pt) that AP8865 can supply to servers/devices?

Question 2: If only a single bank is utilized, what is the maximum power (Pbm) that can be supplied by a single bank?

Question 3: If any two banks are utilized, what is the maximum amount of power that can be supplied?

Question 4a: Are the C13/C19 outlets wired as Delta or Wye circuits?

Question 4b: Are the NEMA 5-20R circuits wired as Delta or Wye circuits?

Question 5: Are the banks wired in series or in parallel?

Bonus information and bonus question: PDU AP8865 plugs into a panel with a 30A tri-pole circuit breaker. Is it possible to trip the 30A breaker (any pole) before tripping any PDU bank circuit breaker, excluding short or failure conditions in the PDU?

@Kinetic Moose spent quite some time on the phone with me, he was quite generous and helpful.

I'm posting my full query above since multiple people have asked...and so I'm sure some people can poke fun at me

I think my understanding is at least passable, there are, however, others who have different ideas on how things work. Neither side is willing to concede.

My buddy was rehabbing a house and I was giving him a hand where I could and moral support where I couldn't.

He goes, "alright man help me move this gas line now."

I said, "mannnnn I was JUST about to go down the way and get some beers. Hey I'll be back in a lil bit though."
