"Listing and labeling"

[renosteinke]

We often use these words, in our quest to properly do our jobs. Yet, it helps to keepp in mind that none of our sources - be they the NEC, the 'White Book", UL statement, OSHA letters, manufacturer statements, whatever - are infallible. You just can't avoid making your own call.

Take, as an example, this product's spec sheet:

By all accounts, this is a responsible manufacturer, making a quality product. Yet, I have to ask: is it NEMA-4X or not? Is there an editing issue or a product issue?

I'll bet others here can come up with other examples of contradictory instructions. Feel free to post your best ...

Of course 'calls' have to be made. UL address that themselves and states it is up to the AHJ, not the installer to make these types of calls.
