Sounds like that's set up for an older electric dryer. And also an older setup for the house - 200 amp feed has been the standard for some time now.

If memory serves, sometime back in the 90's they made a change to the NEC, such that on all new applicances and installs they did away with the older 3 prong plugs (that tied neutral and ground together), and mandated going to a 4 prong plug with a separate ground and neutral lead.

What you describe inside the breaker panel - ground and neutral being run to the same bus bar - is SOP.

Yep........old dryer and old house. No real need for anything more than 100A when the stove and the dryer are gas.

I can change the socket for the dryer to the four prong socket that fits the generator. Hopefully the cable is three wire with ground.

I never really understood the need for both neutral and ground wires being run separately if they both end up on the same bus bar.
