I have a 4000a switchboard. It has a main switch fused at 4000a. Bus is fully rated throughout the switchgear.
I have a 4000a/3600a fused generator panel that connects directly to the bus of the 4000a switchboard via lugs and 600mcm thhn conductors. 4000a main and generator panel have a Kirk key interlock so power can never be sourced from both
Is this considered a tap? Connection point on bus to the generator panel is over 25ft.
Do the conductors feeding the generator panel need to be rated at 3600a for the generator fuse, or 4000a for the main fuse? Conductors connected to the 4000a rated bus will be energized during normal operations.
