How to run a 240v pump from 120v?
I need to convert 120v to 240v to run a pump. The pump is 2 wire, using the 2 120v legs. There are ~$100 chineese step up transformers available, but these do not work for some reason (I suspect because the conbined volatage of the 2 legs needs to be 0 and a simple transformer isn't capable of this).
So, my question is: Is there a device that can convert 120v to equate to the 2 legs of a 240v system?
