IS THERE A SPECIFIC CALLOUT TO USE FOR CONDUIT KNOCKOUTS?
DOES ANYONE HAVE A CLEAN WAY TO SPECIFY, LETS SAY A HALF INCH CONDUIT KNOCK OUT?

RE: CONDUIT KNOCKOUT
Just give the measurable diameter followed by Knockout and a direction in reference to the view, if it matters (1" Knockout Up). Calling out the conduit size opens the door for confusion because a 1/2" conduit fitting does not use a 1/2" diameter knockout. So are you passing a fitting through the knockout or just the conduit, hmmm.
Also if your knockout requires more specs than that, for UL or Nema Certification or something like that you should specify the complete criteria for the Knockout as it is stated in the applicable standard, which has criteria for integrity of the knockout and possibly enviornmental issues (water tight, raint tight, dust proof...).
RE: CONDUIT KNOCKOUT
thanks for your reply. You bring out some good info to ponder. Also, thanks for pointing out the direction that some enclosures take for certification. At this time the req. for the enclosure are not to cert the box, however it will be considered. I agree that good practice would be to anticipate what might happen if a requirement were deemed necessary. I am not sure what NEMA spec (indoor) I would compare, but I get paid to look =).
thanks again,
