Good evening, all. I have a number of projects where we install receptacles for intermodal refrigerated containers. Each unit pulls about 21 kVA at full load, and I may have anywhere from 20 to 60 or more on a site. Is anyone else working on these types of projects, and do you feel that Table 626.11(B) applies to the loads that fall under Article 626, Part IV? Since these are cooling only loads, I'm struggling a little to understand why I would use a higher total demand load for colder climates, when I know my load should probably go down due to milder summer weather. I'm guessing this was based on increased demand for heat during the winter, but may not apply to refrigerated containers. Thoughts?

Most modern transport systems are heat pump style because the container has to be held within a temp range. That is, they are meant to heat and cool depending on what the control logic indicates. While the refrigeration load is definitely less in heating mode than in cooling, there may be significant run time in cold areas where the contents have to be kept above freezing.
