    No. Prime mover shutdown must kill the mover electrically.

    Like shutting the key off in your car, it stops running and won't start.

    is the generator is its own building or room? put yourself in a fire fighters shoes. Where will they likely approach from? put it there.

    another option is to talk to the local fire marshal about it, after doing your research.

    Can you quote the important parts of this section? I just looked at 2014 and that's what's applicable for this project. However I'm very curious what 2017 says. Thanks!

    445.18 Disconnecting Means and Shutdown of Prime Mover.
    (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.
    (B) Shutdown of Prime Mover. Generators shall have provisions to shut down the prime mover. The means of shutdown shall comply with all of the following:
    (1) Be equipped with provisions to disable all prime mover start control circuits to render the prime mover incapable of starting
    (2) Initiate a shutdown mechanism that requires a mechanical reset

    The provisions to shut down the prime mover shall be permitted to satisfy the requirements of 445.18(A) where it is capable of being locked in the open position in accordance with 110.25.

    Generators with greater than 15 kW rating shall be provided with an additional requirement to shut down the prime mover. This additional shutdown means shall be located outside the equipment room or generator enclosure and shall also meet the requirements of 445.18(B)(1) and (B)(2).

    445.18 requires prime mover shutdown device located outside generator room for indoor installations or outside of the enclosure for exterior installations. Best bet would be to ask your inspector what he considers an “enclosure “ but generally speaking weatherproof cabinet or enclosure.
