Load Calculation

[highkvoltage]

I have to summit a load calculation for a very small project. This is not my strong suit. I am installing a new 100 amp service for a water company at a vault that monitors flow. Heres what I have:

crt 1- 4 florescent lights ballast draw .78 amps
crt 2 - 20 amp circuit with 2 receptacles
crt 3 - Sump pump 3/4 hp single phase that draws 13.8 amps
crt 4 - 20 amp circuit with 2 receptacles.

The way I fiqured this was :
crt 1 - 4(.78)*120 volts= 375 VA * 120% (Continuous Load) = 450 VA
crts 2 and 4 - 180VA per receptacle * 2 + 360 VA
crt 3 - 13.8 amps * 120 Volts+ 1656 VA

Crts 1 and 3 total 2106 VA / 120 Volts = 17.55 Amps

Crts 2 and 4 total 720 VA / 120 Volts = 6.0 Amps

Is that it or do I have to total these and / by 220 Volts giving a total load of 11.78 Amps? What would the neutral load be 11.78 or 23.55 amps?

I know this seems like 1st year stuff and I am contractor but I haven't did any load calcs for years.

Thank you

I would just install the 100 amp service you mention and circuits and be done.

The sump motor at 125%
Lights at 125% only if they are continuous
Receptacles at 180va each

Does 3258va load sound good to every one?

I would love to but the plan reviewer that has to approve the drawings I summitted wants the load calculations.

If it's in review does he need the panel schedule with calcs?

A panel schedule was provided with drawings.
