I have a customer that is wanting to convert some newer upgrades of a grain operation into 3 phase. Currently all that is available is a 400 amp single phase 120/240 service. Now in the past we have considered installing a 3 phase service but it has proven to be more costly considering this is a seasonal operation. Taking that into consideration, I believe that at this point, it is wiser to itstall a phase converter for the time being.
Can anyone give me some leads on some calculations to determine what I will need to install. I will be operating a 25HP, a 7.5HP and a 15HP, respectively at the same time. What I need to determine first is what the sigle phase load will be while these are running. There will be other single phase 240VAC loads running at the same time also but I am mainly concerned at what this new load will be.
Thanks
Kevin
