I posted this on another thread here at Mike Holt Code Forum, but did not have any luck with an answer. Perhaps I chose the wrong thread, so I am attempting it here....
In the factory manufactured main lug circuit breaker sub - panel for swimming pool motors and equipment, the manufacturer states that the CB?s have to be rated at 10,000 amp interrupting rating.
The minimum standard CB?s have a 5,000 amp interrupting rating. I know the electricians have to use the proper interrupting rated CB because it is listed by the manufacturer, (110.3 (b) ) but my question is why this installation for pool equipment requires a 10,000 amp interrupting rating instead of the 5,000 .
I would like to be able to explain a little more than just "because the manufacturer listed it for 10,000 amps." I know that in itself is a legitimate reason and cause enough for a correction notice, I am just looking to help the electrician by finding a reason WHY - in other words, to help clarify the INTENT of the higher rating.
Any help would appreciated!
