Hasn't somebody, ken480 maybe posted a slang dictionary before ? Could it be a permanent post for green guys to refer too ?
- round house, full boat: 3 PH MWBC black, red,blue, white
- cow boy, mini made by Minerlac Co; pipe hanger
- conduit, pipe, Rigid, IMC, EMT, PVC: all refer to circular products usually 10 feet in length, some times 20 feet
- the list goes on
the problem is, the list has regional distinctions.
greenfield, smurf tube, battleships, there are a thousand
different dialects of sparky speak, and half a dozen
geographically diverse words for the same piece of
material, or equipment. enough so that experienced
electricians from different regions sometimes have to use
subtitles when communicating what they want.
the problem is, the OP doesn't have first hand experience
with a lot of this stuff, so extreme clarification is sometimes
necessary. we have spent a number of pages of posts trying
to explain the difference between thinwall conduit, and GRC.
to which there have been comebacks of..... "but isn't it metal, too?"
or words to that effect.
as the OP seems to be in an estimating capacity in his place
of employment, rather than argue about the differences in
labor between EMT and GRC, he should simply bid everything
requiring conduit, with EMT labor units.
then, the first time the specifications require him to use GRC
when he bid it as EMT, the resulting loss of working capital,
perhaps even resulting in the loss of the company,
and resulting beatings from principals in the company, will
impress upon him the exact difference between the two raceway
systems with far more clarity and permanence than anything
we can say here.
i'll bet a cheeseburger that he never forgets the difference again.
