Anyone who digs up an obsolete copy of something to prove that he has
the "right" to create a safety hazard has a larger problem than we can
help with here.

## Agreed. It baffles me why the code allowed for NO grnd conductor between
building ..
back in 2010..that is fubar. Why the 4 wire code in 2011, when everyone else
had it eons b4.
## here we cant even buy electrical cable that does not include a ground wire.
Its been like that at least as far back as 1960, here in VE7 land.
## In fact, the ground wire is not included in the conductor count in any
cable.
What electricians call 2 wire, consists of 2 conductors...plus a ground.
Whats called 3 wire cable is 3 conductors plus the ground... 4 x wires in all.
## I wonder if 4 wire was cable was available to K9YC back in 2010, when
he installed his 3 wire sub feed ?? If it was, it would have been prudent
to have bought
and used it.
## will the electrical code allow him to install a separate ground wire
between buildings,
then REMOVE the grounded neutral in his sub panel ? That would be the easy
fix.
If not, I would suggest to rip the 3 wire cable out....and do it right this
time...and install
the requisite 4 wire cable. Then the neutral in the sub panel is not
grounded. Then
all fault current flows through the grnd wire...back to the main 200A panel.
## what you need to do is..... upgrade it such that it meets the current 2014
code.
