Hmmm, the 06 IRC and the 05 NEC seem to be in agreement according to
my stuff, and they're a bit different from what your guru told you.
The maximum height of the breaker is 6' 7" and the minimum height of
the working space is 6' 6" x 30" wide by 36" deep.

Looks like I need a new guru (or one with a better memory).....

Now I know who to ask for answers to my electrical questions. :)

cheers

Errrr, I wouldn't let the guru go just yet. He was close enough for
spit, and I have to look stuff up to verify. I remembered the 6' 6"
working space, but when someone posted the 6' 7" breaker height, that
seemed odd so I had to look it up. I wonder why they wouldn't just
make both requirements the same number? Needless fussing for an
inch. An inch hardly matters...most of the time!

I'm the guilty party. :-)

In both cases the 2008 NEC says 2 meters. So this is just an example
of standardizing on metric and and two different code writing
committees using different rounding practices. In both cases the
rounding practice is to minimize the restriction.

Cheers, Wayne

Interesting. Thanks for clarifying that, Wayne.
