Those guys don’t know, plain and simple. They think they do. That’s the problem.e

We have a site with a lot of temporary job trailers.
Designers, architects, job super, etc told us the loading was 2.0MW.

We installed a 2.5MW 480 XF and recorded loading.
So far the highest demand after a year and a half was around 700kW

Well maybe they were hedging for a peak load at lunch time when all the microwave ovens come on.

Here is the trailer schedule. Also do you think I need to input 3% VD for temp situation.

Use 80 amps for the calculation. IMO for a temp trailer you probably don't need to use 3% but if that's what they're paying for then you should. If the voltage is a little low the heat and water heater will take a little longer to heat up.

I agree. Another reason to stick with 3% is to prevent problems for other equipment when the AC kicks on
