JV Wouldn't the lack of a U/L evaluation (or other NRTL) be a problem?
It might be cheaper/easier to fix the one he has. What's wrong with it? Are the parts available? It is possible a "120v" version is just a 240 with some contacts removed. For that matter I am not really sure why you couldn't just use the 240v version and not hook up one phase. The function is the same.
