Lets tear up some walls and pull wire, without any knowledge of proper
codes. It's like your recent suggestion to replace the fuse box to add
grounding. "Just yank it out! remember where the wires go!" Who needs
electricians? (Bzzzap!) Perhaps you are a member of the Burridge school
of electrocution theory: "Nobody ever dies of electrocution, they just
move into another reality where they didn't actually die, they only came
close..."

Why exactly is it a stupid idea? Is it dangerous? Expensive? What's the
problem? Educate me. 30A inverters are relatively cheap, as are auto
batteries. Seems far safer than trying to merge two circuits. Hell, you
don't even know how often or for how long he is using the thing. If he
uses it once a month, seems like a waste of money to have his circuits
upgraded and his wiring replaced.
