7.10 An opening in the enclosure that has a minor dimension of less than 1 inch (25.4 mm) is acceptable
if a probe as illustrated in Figure 7.2, inserted through the opening, cannot be made to touch any

in all possible articulated positions before, during, and after insertion.
7.11 An opening that has a minor dimension of 1 inch (25.4 mm) or more, in an enclosure, as illustrated
in Figure 7.3, is acceptable if, within the enclosure, there is no uninsulated live part or film-coated wire

T equals the enclosure thickness, R equals X minus T, and X equals 5 times the diameter of the largest
round rod that can be inserted through the opening but not less than 6-1/16 inches (154 mm). In
