I recently bought a wood planer. The id plate on the motor tells me it is 3 hp wired 220 single phase. The planer plug has three prongs on it. I plan to use this in my shop. My shop is powered with a 7000 watt generator. My generator has 220v but it has a 4 prong plug. CAn I change the plug on my planer? Will this be enough power to run the planer?
Do I need a ground rod from my generator for something like this? Also is there an adaptor I can use?
Thanks to anyone who could help. LAndon.

The generator should handle the 3 HP motor fine, may not be able to handle much more other load at the same time, lights should be no problem.

Just change the plug to a four wire plug, and use the two hots, brass screws, and the green for the equipment ground, leaving the neutral, silver screw, unused.

If this genset is used on permanent basis, a ground rod connected to the frame of the machine should be installed, along with checking with the manufacturer's instructions.
