@dafyre , good point, I edit the wording. See above. Really I mean current on each phase. Poorly worded. Sorry!

Don't try to answer electrical questions with IT answers. lol

@art_of_shred Actual operating load is the most practical.

How would you measure this in an environment without power monitoring? Or is it basically a guess at that point?

Is there a simple percentage to use there as a ballpark figure?

An ammeter works great if you have one and want real numbers.
-
@art_of_shred 70-80% is a safe bet. Sometimes it is lower, but that is typically what I default to when sizing.

Even in the afternoon or do you have to switch to a PMmeter?

Yes! These can be somewhat inexpensive. We usually see IT equipment running at 60% or less of nameplate rating. The challenge we have when sizing a UPS or PDU, and you will have too, is that generic rules always bite you at some point. If you are the exception, you risk taking down everything.
Keep in mind that sizing a UPS or PDU at less than 80% or 100% utilization is a good thing. UPSs and PDUs are like the breakers feeding your Christmas tree lights - Once you add too much, the lights go off!

Once again sporting your prowess in all things electrical. I defer to your expertise...

Couple of ones that might be more home oriented than business:
- Do you have any plans to get into the home battery market, like Tesla? (or are you already) These are the backup batteries that you can charge from solar and then power your home from (or use as a backup for if the power is out).
- What would you recommend in the prosumer market for IT pros or technically minded folks to use at home?

Keep in mind that sizing a circuit at less than 80% or 100% is a good thing. You never want to completely oversize, but UPSs and PDUs are like the breakers feeding your Christmas tree lights - Once you add too much, the lights go off!
Just to clarify, I thought that was worded a little confusingly. You never want your load to equal or surpass your protection. Ideally, your expected amp load should only be about 80% of your protection's full capacity. Otherwise, you can exceed its ability to protect and either diminish its performance or nullify the protection altogether.

That didn't sound good when I read it, so keep your mind out of the gutter.

Too late.
-
Are any of your PDUs capable of being remotely managed? So we can power stuff on / off remotely?
-
Do you offer and trade in discounts for large UPSs to switch to Eaton? We currently have Liebert 3 Phase UPS systems.
-
-
What do you see as the future of battery technology in UPS units? Does lead acid still have a future in these kinds of applications?
-
Looking ahead 10 years what do you see as potentially disruptive technologies that might enter your field?
-
Of your products, is there any one you or the company is particularly proud of? Why?
-
The core of your business is design of power supplies - have you ever considered making consumer/"prosumer" ATX power supplies?
