Reducing breaker setting and conductors

[electrofelon]

Just a sanity check here. So on this 2000A breaker, i can turn thr long time down to .4 and use 800 A conductors yes?

Yes.

There is a lockable/sealable cover over the breaker setting. You meet the NEC as it does not require the settins to be inaccessible.

Thanks jim

Those are factory-default settings. If you're trying to coordinate with anything, let me know what the device is, and I'll send you the settings. I have access to a network package of SKM.

Awsome thanks. Its probably not very critical in this case, its the breaker on a 400 KW generator (120/208). It will be feeding a 2000A transfer switch then a 2000A switchboard horizontal bus with 2 sections.

The rules for this are in 240.6(B) & (C). Most breakers fall under (C).
