Please help me with this HVAC load calculation

[Stickynickey]

I have a 200a, 480v panel currently feeding 5 HVAC units that are 40a a piece.

The customer is requesting to add 2 additional heat pumps on the roof. The 2 new units draw 43.8a each with a MOCP of 50a. Do I have enough power available to feed the additional 2 units?

Thanks much.

This sounds like a study question so what is your answer and how did you arrive at it.
