I recently ran a circuit for a vehicle lift for a guy's shop. When I first looked at the lift I had no specs only the info plate on the motor which stated that it could be ran on either 208-230V @ 17.8-16A max load single phase. I installed the circuit which is 50' from the panel as a 20A and I got a voltage reading of about 243V. I received a call from the owner who said after installing the lift they plugged it in to run it and it will only get about a foot off the ground before it trips and the motor gets extremely hot in that short period of time. I went back there and put my amp meter on it and it spikes as soon as the lift is engaged, I then put a 30A breaker in just to see if I could get an amp reading, which did the amp reading was up around 28-29A the lift would operate but once again get extremely hot. It was then that I saw the manual and started to read through it and that is where I seen that the motor was wired for 60Hz and cannot run on 50Hz without physical change to the motor. I am not sure what Hz reading is for his electrical service at his house. My question is could this be the reason for the high amp reading and extreme heat being generated?
