Re: (ET) Tool receptacle

["Christopher Zach" <czach computer org>]

Actually there might be a solution (there's always a solution :-)

Way back in my pile of junk is an old DEC TC01 DecTape unit from the 
1960's.
This unit used the same twist-lock plug; however it had a third round pin 
in
the center.

That was the ground. My guess is Hubbel built an ungrounded version (the 
one
on the ET) and one that had a hole in the center for plugs with three
prongs. As per NEC codes, one could plug an ungrounded device into a
grounded receptacle, but one could not plug a grounded device into an
ungrounded receptacle (think normal 2 and three prong outlets)

Thus if I can find one of these, I could retrofit the tractor, have my
ground (which would be nice, because someday this system will charge off
20amps of solar) and plug in ET devices when needed.

Anyone know if that outlet is fused with a 20-30 amp fuse?
