Hey guys, I know this is not complicated, but cant seem to find any info on the proper wiring/ install for the estop. I have not had to install one yet, and I'm sure I can make it work, just looking for the "proper" way per Generac etc. Also a side note, as I'm looking at this estop and its not lockable in the open position, I'm wondering what's the difference code wise between this and either one of the 2 that come on the generator itself?
 
What do you mean by lockable in the open position?
If you mean Using a lock to make it unopearable you have defeated the purpose.
If you mean it is momentary contact and doesn't require a twist to reset, the generator will restart as soon as you release the button.
 
I haven’t used that one, I usually just get an off the shelf Estop from the supply house, like an ABB.

But all of them are just series wired stop switches. Cut one wire at one of the switches and wires the Estop in series.

And the Estop is not required to be lockable open. The generator is required to be lockable in the off position, which is accomplished by the lockable lid with an off switch inside.
 
Wow, soo sorry guys. Thank you for the replies, apparently my phone logged me out so i never got the notification. and...

445.18(A) says " Each disconnecting means shall be lockable open in accordance with 110.25

Respectfully IMO...

makes sense if i turn off the breaker and lock the lid there is no issue but that would be up to AHJ as that is not really what the code says. that would be like saying i don't need a breaker lock if i just lock the door on the electrical room. makes perfect sense but does not quite satisfy the code. at least in the wording sense, in the intent, absolutely.
