My Dad (Master Electrician) shows the Electric inside a Data Center, and it’s wired, Thoughts?

So, this drop down, and we'll That's how much power. And now we're going to go into the data center. >> Yep, let's get it. You could see a crack unit in the data center. This is taking air in from the top, cooling it, and blowing air underneath the raised floor, and goes into these little holes here. Like you could feel air coming up from these holes inside. >> feel the heat coming out of here. Put your hand here. Feel that heat. Oh, yeah, it's hot. That's That's how much power is coming out. Now, these are called an RPP panel, and these are typically just Square D QOB panels. Take a look. Square D QOB, Square D QOB, one main from PDU 2B, and this is 9C and 9D. If we go on this side, remember I said everything's redundant? >> Yeah. So, this is fed from PDU 2A, 9A and 9B. So, one side is AB, the other side is CD. When we feed a network rack like this, you want to ensure that we have two individual feeds. Okay. Okay, from two different sources. That means if one of the PDU fails, the other side takes over. What we don't want is any type of brownout, power drop, power loss for a fraction of a millisecond. We don't want that. >> No, that's not good. Now, what we're going to do today is What's the service call today? We're going to install three more new racks right here. One, two, three. They need a specific five-pin 32-amp IBC connector. It's a pin and sleeve connector. Cuz we're going to put it on a three-pole breaker, MC cable under the floor and to these disconnectors. So when the IT guys install the network cabinet, they can connect into it. So we need to put in six 10 4 wire, two, two, and two and we need to come from this series of panels here. So this drop down and we Okay. So we got to get a wire down there. If you notice it's all MC because it's plenum rated. Right? Can't use Romex. You could use EMT, MC cable. No rubber cord, SO cord, SJ cord is not plenum rated. All right, let's get to work. Let's get to it. Okay. I'll start getting the wire. All right.
