Does the inspector inspect for 'worst case' or do they leave that to the field scoring judge ?

Q. The Allen-Bradley gray, black, red distribution blocks - where does the 2 thin grey pieces go ? and are they necessary ? And why do the wires keep coming out of the block so stinking easily ? I don't remember having this problem in the past.
Ed,
The 80" cylinder is question we will all struggle with this season but I would interpret the rule that your failure mode may very well violate the intent. Best asked on the Q&A for clarification.

The thin grey pieces are needed when the block is used for high voltage. The Kit Of Parts Rev A has a drawing on how to assemble the block and they are not included in that drawing. The wires pull out if they are not stripped 5/8". When you insert a correctly stripped wire, the end of the wire should contact the inner plastic wall (wire stop) of the block and you should be able to just see bare copper at the entrance of the terminal. When you tighten the clamp, the wire will be secure. Add appropriate wire management so that the wire does not wiggle around in the block and you should be fine.
