OK as you can seen main feeder needs to be tapped to the panel/fco sub feeders. The 225 tags are 4 #2/0 w/#4, the 100 tag is 4#2 w/#8 and the main 400 is 4#500 w/#2. I'm not clear on which conductors would be tapped/spliced together to accomplish this? Would it go like this?

1 hot #500 to each sub feeder/fco hot....this would happen four times. Thinking a Ilsco tap with one port for the 500 and 4 ports on the other side.
1 neutral #500 to each sub feeder neutral..
1 ground #2 to each sub feeder ground


How long would these splices take.


Thanks.

Yep. 4 of these. The 4 (or more) ports for other than the #500 must cover the range of at least #2 to #2/0.

Then you'd need a similar tap block for the ground... but 6 ports so you can install a #2 jumper to the box (assuming it is metal).

How long IDK.

The maximum OCPD that a 2/0 tap conductor can land on at the load end is 175 amps. If the load end OCPD is 225 amps, these conductors need to be 4/0.
 
The 225 amp taps need to be #4/0, 100 amp taps need to be rated for at least 133 amps (25' tap rule). All tap EGC's need to be a minimum of #2.
