I am converting from a 6.5kw NH Onan Generator to a 6.5kw NHE Onan Emerald III Generator.  The NH generator is a 120/240 volt generator and the NHE generator is 120 volt.  

I am also eliminating the automatic switch from shore power to/from generator power.  I will replace this switch with a male 50 amp plug.  There will be a female plug wired to the generator that is used when generator power is needed. and a normal 50 amp cord is used when shore power is needed.

 

The dilema is that the wires out of the NHE generator are two black wires, two white wires and one ground wire.  Coming out of the breaker box on the FMC are one red wire, one white wire, one black wire and a ground wire

.

How do I wire the two 120v circuits into the female plug that comes out of the generator?

Do I wire the two white neutral wires together and connect them to the neutral prong om the outlet?

Thank you in advance for your help.
