I recieved a call for a new LAN/Gaming business.
there will be about 32 computors with LCD Moniters.

How many circuits should I allow for this

I can tell you for sure, the figure you think you need is way smaller than what you really need.

Id say somewhere around 4 - 6 circuits. Dont forget to add in the wattage used by the networking hardware, and a server or 2.

and the UPS overhead.

I am still going with 6 circuits, or 3 MWBCs

I would go with 32 circuits, not counting servers or other house loads, I would put them on two separate panels, and I would use separate neutrals (no MWBCs). I kid you not; that is what I would recommend to the owner.

This is not about the amount of load, nor about minimizing the cost of installation. It is about the reliability of the power supply, and the continued availability of each and every item of gaming equipment. Under no circumstances would the owner of such an establishment want to have to shut down two systems, in order to work on the power source to one system. Every item is a revenue generator, and every item that is out of service does not generate revenue.

I agree.

But if money was an issue, I might cut it back to 16 circuits.

I'd echo the no MWBC approach. All non-linear loads. Avoid the possibility of trouble.

So, What do you think the 120/240V twist lock on the back of a UPS is when a PDU is plugged in and breaks that out into 120V recepts?

1 circuit per computer is out of line - with all due respect charlie. I have been in charge of a big lan party before - network and power, and if we were to use 1 circuit per computer, I would have needed a few 80 space panels.

Normally I would agree. But gaming systems are different than other network applications. Most office computer systems are not individually used as revenue generators. Imagine a Las Vegas casino having to shutdown two side-by-side slot machines, just so that they could work on the one that is broken. During that entire maintenance period, they would have one fully functional slot machine that won't have a person tossing coins into it. That is the essence of my suggestion.

Can we say; UPS, redundant HVAC with generator backup?

Of course. But then, we really don't know the nature of this "business establishment." So we don't know how much revenue would be lost for every computer that is taken out of service, and thus don't know how much back up equipment is warranted. I do presume, and I hope I can presume safely, that this is a legal gaming business? :D

Were talking about cord connected equipment though, Pull the cord if you need to work on the computer.

He should use Spec grade receptacles, so maintenance on the actual circuits are reduced greatly. Maintenance should be scheduled off hours anyway.

He should also consider that there are computers that require a 20A circuit by them selvs - I know, I own one. THe PSU comes with a NEMA 5-20 Plug.

Depending on how far he wants to look in the future, he should consider more circuits, and stagger the circuits, so that 1,2,3,4 are NOT all on one and 5,6,7,8 are on another. He also didnt specify if this is single or 3PH.
