My 5 HP air compressor motor is 110 volt?
Isn't the ramsplitter quite expensive?
Air compressors are one of those devices that are notoriously overrated by their manufacturers. AFAIK, this is the breakdown torque developed right before the motor stalls and is an unrealistic rating. It can't maintain this rating for more than a few seconds and when was the last time you stalled your air compressor? It is better to rate a compressor by CFM @ a set pressure, usually 90 PSI. 5HP@120V is about 60 amps, BTW.
I have a new Ramplitter 20 ton and the 3HP motor peaks out at about 20 amps on 240V. It was $1555 delivered and about 50% more than the 16 ton unit, but comes with high speed tires and a 2" hitch. I have a tendency to buy the largest tool that I think I will ever need. The 16 ton might have been enough, but I didn't want to chance it as I never know what kind of garbage the tree guys are going to drop off. We scroungers can't afford to be picky! There are cheaper 20 ton splitters out there, but none that are available in electric versions. These things are touted as "rental duty" FWIW. I have bent other splitters before!
Large motors should be run on the highest voltage available. They are more efficient due to less voltage drop and the wire can be half the size at 240 volts. If you have a 50 amp welder receptacle anywhere, you are already there, or you can bug it off a central AC unit. I bought a 10 ga extension cord and whacked the ends off it to use on the splitter. SO cord would be a classier way to do it, but I have never been mistaken for being classy!
