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.
