Hello, I am trying to find a definition of 445.18 to explain the following "The revisions to 445.18 now indicate that the remote manual stop cannot be located on the enclosure, so that verbiage is more stringent than NFPA 110. " of https://www.ecmweb.com/national-electrical-code/article/20902695/generator-shutdown-means

(A) Disconnecting Means. Generators other than cord-and-plug-connected portable shall have one or more disconnecting means. Each disconnecting means shall simultaneously open all associated ungrounded conductors. Each disconnecting means shall be lockable in the open position in accordance with 110.25.
