Thanks to all for your responses.
Actually, here is the problem. In doing design, the electrical group has to know at least some approximate loads for a building and the process before we can begin to size the services into the building/plant. Usually the HVAC can give estimated tonnage for the process and building cooling. They won't (until they consult with the local Trane rep.) give anything more. So for planning purposes, we the electrical group must make some conversion from tons to KW, KVA, HP or Amps. Someone before me has calculated that an 800 ton unit is 492KW. Now I must verify that information.
If a 0.6 factor is used, the answer is 480KW.
Wolfdog, can you be more specific? Thanks.
