Hello to any of you out there that like to do load calcs. :happysad:
At the last minute I received word that my project needs load calcs, so I figured I'd hire an engineer and get it done quickly for submittal with plans. Well, not so simple around here. I guess everyone's pretty busy. I figured I'd take a stab at it myself, and though at first it seems pretty easy, I am wondering if any of you pros out there can help wrangle me through this one, perhaps help me out on a few points.
Project Data:
Office Space: 8,491 Sq ft
Existing Service: 120V, 3-phase service
# of outlets: 130
Other Equipment: copiers (6 is a fair number for the number/size of office suites in the building)
A/C units: (6) 3-ton units. I guess some other data is needed on the units. I know they are 3-phase sytstems and are rated for 40A services.
Anything else?
I started the calculations and was a little puzzled by some of the numbers I came up with. Wasn't sure what to do considering there is a 3-phase system for the A/C, and how that factors in. There's an awful lot of references and clarity becomes more and more difficult as you refer to each reference upon reference.
Any pros out there who do this stuff eyes shut want to throw a tip or two my way? I need to learn how to do this anyway but it seems like a very simple project and I know someone out there will look at this and be able to ask the right questions and guide me through it.
I'd really appreciate help from anyone that likes these sort of things and has the time to tackle it.
Thanks!
Bob
