i just got done wiring my garage and as we forgot to buy one, he just told
me to go buy one later and put in a 220V 30A outlet. we wired it to the
panel and all, just left the wires loose in the box which is located right
below the panel.

the electrician told me to run the copper wire to the neutral prong instead
of the white wire. his reasoning was that a loose copper wire in the box
could accidentally touch one of the lugs that was hot, but you could just
wire nut the neutral and it wont touch anything. this way i dont have to
trim off the copper ground wire and if i ever need to i can switch to a 4
prong outlet instead of a 3 prong one.

now i know how the neutral and the ground are related and connected, and i
dont see a problem. but im not an electrician.

so my question is, is the inspector gonna have a fit or is this a common
practice?
