Q: Hello, I was curious if the Cummins Onan QD8000 could be wired to accept a standard 50Amp connection for our concession trailer. We are looking into replacing the portable 5K generator we have and mounting it on the front of the trailer on top of the tounge of the trailer. If it cant be wired for a 50A/4 prong plugin, can purchase a fuse box that would allow us to adapt our trailer to the generator? Any opinions on options would be appreciated. Thank you!

by Keith Dalton from North Dakota on March 30, 2014

A: This generator will not work with your concession trailer as the generators output is 120V only and cannot be converted to 240V per your 50A 4 wire information. This unit is designed for use in RV applications only and not recommended or designed for use in a concession trailer. We recommend you search for a true concession trailer generator that outputs 240V and comes with the appropriate warranty.

When you get years of reliable service out of your old unit you can rest assured that you will get the same quality and... more
