Minimum space from center of pipe or conduit to nearest obstruction.
1. Dimensions in top row (boxed squares) are centers for conduits of same size.
Example: How close may 3” conduits be spaced? Answer 41/2
2. Dimensions in light blue shaded squares are for centers of conduits
NOT of the same size. Example: What is the minimum spacing for 2”
and 3/4” conduit? Read down column marked 2” to figure opposite 3/4
and find dimensions is 219/32”.
Note. Minimum spacing dimensions as shown will give
approximately 1/8” clearance between locking nuts.
