retail space

I am negotiating terms with a realtor. The retail space I will be occupying does not have all the power outlets I need. The following is a list of things I need to "plug in"

72 Computers with 17" monitors 1 Full size Coke Vending Machine 1 Full size Snack vending machine (no cooler) 6 - 16 Port switches 6 - Servers w/ no monitors 6 - 12" Neon tubes 1 Full size fridge/freezer 1 Full size Deep Freeze 4 32" Televisions

I don't want to have breakers tripping all the time... What do I need to request the property manager to do to upgrade the electricity to handle all of the above?

You will need a minimum of a 200a service. Your computers might pull close to 100a by themselves. You didn't say anything about a copier and maybe some laser printers.

a couple ink jets.

So how many systems could I put on a breaker? Is it better to go with 30A instead of 20? eg. cheaper on wire

Would the power have to be upgraded? or would they just have to install a new box?

How many computers can go on 20A or 30A ?

what should I tell so that they upgrade to exactly what I need?

The NEMA 5-15 line cords will limit you to 20a circuits. Without kicking the "how many amps does a PC draw" tar baby I would say you should plan on 300w each and only load the circuit to 80% so say 6 or 7 systems per 20a circuit. If you actually have an amp probe reading you can get a better number.

So would this work (20A)

That looks reasonable but I would buy the bigger panel (more slots) in case you wand to split up the loads a little more or want more stuff. You really need some real world measurements of your PCs since 75 times the error in our guess, adds up.

Why not give the broker this list?
