Concentric and Eccentric Knockouts

[finhead]

Category Code BGUZ, page 25, or the 2006 UL White book has a paragraph dedicated to concentric and eccentric knockouts.

The same Category Code in the 2007 UL White book, page 67, does not contain a similar paragraph

Does anyone know if this was a conscious omission, or how oversized KOs are to be evaluated?

Thanks,
Brian Dolan

I'm not sure. I was wondering, does the white book mention tangential KO's?

A point well taken.
Yet another shortcoming. And what about eliptical KOs?

This kind of questions send me into orbit....:roll:

No, but it mentions single- and multiple-stage knockouts. (QCMZ) :smile:
