Hello and welcome to Just Answer. My name is ***** ***** I will be happy to assist you with your electrical question.

1) Take a look at the gen set receptacles and confirm the NEMA ratings.

Most likely the 30 amp is a NEMA rated L14-30R which consists of 4 conductors..... ie..........2 hots, 1 neutral and 1 equipment ground. This would be a combo of 120/240 volts.

The 20 amp receptacle will only be a 3 wire 120 volt circuit which will have 1 hot, 1 neutral and 1 equipment ground.

2) Where are the wires located that you are referencing? Inside a plug-in cord or other? Do you have 2 separate cords that are plugged in at the generator?

3) Please confirm what you have and we can take it from there..........Thanks.............Kevin:)
