    220.87 Meter Readings

    This is an excerpt of the meter billing on a project I am quoting.
    the 1.58 in the Demand Rdg column is the highest over a two year period.
    How do I use this for 220.87 Determining Existing Loads?

    Service is 208Y/120V.
    Original load calculation on panel schedule was 186.539KW = 518 Amps.
    heat load was 91KW

    So, what I'm thinking is you multiply the 1.58 times that multiplier of 60 which would give me 94.8KVA which would be about what I would expect in the dead of winter with 90kw of heat in the building.
    Multiply that by 1.25 per 220.87 gives me 118.5KVA.
    600 AMP 208 service = 216KVA
    216 - 118.5 = 97.5KVA or 260 amps available.

    Am I thinking right on this?
