Sounds about right to me. When we installed the newer Delta V (with GC-GCCIII and EA-ConfloIII) with a new power conditioner rated for 8kVA (instead of the old single phase transformer), the electricians had to boost the Amps on the circuit breaker to 40A from 30A. And looking into back power generation for the building recently, the 37A-38A number came up. (We are getting an UPS to replace the power conditioner as part of that project.) -- Charlotte Lehmann Assistant in Instruction Bates College Department of Geology 206A Carnegie Science Building 44 Campus Avenue Lewiston, ME 04240 Phone: 207-786-6485 FAX: 207-786-8334 Quoting "Lora L.
