Nec 250.104(b)

When it comes to other piping, [NEC 250.104(B)] what does the term ?likely to become energized? entail?

I consider that somewhat self explanatory, in the right conditions or catastrophic failure is there energy available that is likely to "mingle" with the addressed installation.

I hope this helped you, but I will say that mine is not the only interpretation out there and this question should be addressed to your AHJ if you have a specific problem.

Good question.

I feel that the only entity that can really determine what would be "Likely to become energized" would be the AHJ.

Offering my normal explanation:

The NEC style manual tells code authors to use the Merriam-Webster dictionary to determine meaning of word not identified in the NEC.

The common dictionary definition of "likely" used in this NEC context is "probable". While "possible" is also a valid definition, I feel it is not "likely" the one the code authors intended.

" likely to become energized " , is 100% pure code speak.

 

[electricmanscott]

AHJ..."Is that piping likely to become energized"

Me..."Nope, all the wiring here is done 100 % to code"

 

[Pierre C Belarge]

AHJ..."Is that piping likely to become energized"

Me..."Nope, all the wiring here is done 100 % to code"

I agree, if the install passes inspection and is wired completely to code, how is it likely to become energized.
Oh, wait..."what if". (I do not like that statement)

Any place this phrase is used, needs to be addressed. What are they really trying to say????

According to NEC Manual of Style, the definition of "likely to become energized" is "failure of insulation on".

Jim,
Based on panel comments that say "likely to become energized" is the same as "may become energized", I think that "possible" is the intent.

Those comments really frustrated me...

That may be what they want it to mean, but the two do not mean the same thing.
