Greetings all: In clause 3.2.2 allows the provision of knockouts, cable entries, etc. in lieu of a non-detachable power cord for permanently connected equipment. In Table 10, it lists the overall diameter of conduit based on the number of conductors involved, up to 16A.
In my particular application, there are 2 wires plus earth, and the current (and the branch circuit protection) is less than 16A, so the table tells me I need a knockout that can accommodate a 16.0mm O.D. conduit. If things are done there anything like they are done here, this 16mm conduit will be secured in a fitting of some sort, and the knockout needs to be matched to the fitting, not the conduit (i.e. a 16mm hole is likely too small). Is there a reference, or can anyone tell me, what the appropriate sized hole will be? Is this standardized somewhere?
