I was doing some work today for API (air quality samplers) They have portable rooms to ship to other country's (China in this case). Had to temp power 5 units with a gen. 230V 50Hz. Two rental places would not rent a gen set. The one that did said they set it up to specs. They got the 50Hz right but had 240V phase to phase. I had to make some minor adjustments but it works great. Last week it was an industrial bailer set for 230V 50Hz. Is more stuff coming over with odd (for us) power requirements? I love my job something new every day. Rod
