We tried once in a continuing ed. class. In attendance were the Director of Inspectors, two city inspectors, two state inspectors, and around 450 electricians. They would not budge on this because of the phrase "four quarter bends". Maybe I'll submit a proposal to have that verbage removed. Just to see what they say.
Well, your proposal may be a little late and you can show this to your local inspectors too.
From the 2001 ROP's
8- 219 - (345-11, 346-11): Reject
SUBMITTER:
Bruce Mitchell, Thornton, CO
RECOMMENDATION
:
Revise text to read as follows:
The cumulative total of all angles formed by bending of the
conduit between pull points (e.g. conduit bodies and boxes) shall
not exceed 360?.
SUBSTANTIATION:
Current language is imprecise and could be
interpreted as implying that any bend greater than a quarter (90?) is
not allowed.
PANEL ACTION:
Reject.
PANEL STATEMENT:
The existing text adequately explains the
requirements for conduit bends. Four quarter bends is used as an
example and does not limit the angle of any bend to 90 degrees or
less.
