Any electricians available? Wire size question...

Yes, famousbob, you can do it that way but it creates a shock hazard not to use the neutral wire in addition to the ground wire on 110 service. You've got to take each leg of the 110 paired with the neutral, not with the ground, in order to meet the code.
Don`t remember , but no problems w/ any shock or grounds. neutral and grounds were used at time of hook up.
