Ouch. I hope they paid for repairs.


They did. I cost them quite a bit: that was a 5000 psi 15 cfm air compressor
originally designed to pump up the oleo struts of B-52s. I used it to fill
scuba cylinders.


Now, many years later, I'm dealing with 220V single phase power at the house.
Does it make any difference which [hot] conductor goes to which blade on a
220V plug?

Not at all.


Thanks very much. This 220V stuff is looking easier all the time.
