	Total up all the load requirement , kW, divide by a power factor 0.7 to give you the tranformer kVA rating, add a reserve margin appropriate for the location, e.g., to provide for future growth in demand. __________________ Sharing knowledge is one thing that defies basic arithmetic logic --- the more you share, the more you get!

	Not all of the connected loads may be running at once. 1) You may be able to assess the maximum concurrent load, and size for that plus a reserve of say 15% to 25%. And/or 2) There may be diversity factors that you can apply to multiple loads of similar types. Local codes may dictate what is permitted along these lines; make sure to consult them. Because of such local variations, it is impractical to give a universal answer. __________________ In vino veritas; in cervisia carmen; in aqua E. coli.

	After reading Tornado's answer, you don't have a chance. Hire an engineer that know what he is doing.
