Tapping Riser

Sounds tricky, but maybe not. If you are physically cutting a new tap box into an existing riser, that may be a challenge in itself. You may need to support the vertical conductors that are below the box. I would recommend a mounted connection block with a cover, not the floating insulated variety your link took me to.

In order to accomplish this without replacing any of the conductors, it's going to be a challenge but not necessarily impossible. You must complete the parallel wiring on the existing sets of conductors, then tap each parallel connected set.
 
You'll need a 3 port Polaris or some other type of connector for three conductors. The #3 EGC with the tap conductors is likely too small.

Agreed. So in my mind this is what happens.
1. Install new 3-1/2" pipe and wire to point near new splice box and new panel
2. Shutdown power to existing feeders we are tapping.
3. Cut existing riser conduits/feeders, support feeders.
4. Cut in new splice box.
5. Finish new 3-1/2" conduit install and splice/terminate.

Sound right? Thanks.

I think you are on the right track, I would allow for some adversity.............

If the existing is a parallel run, then a 5 port connector would be needed, right?
2 in, 2 out and the tap.

Oops, yes you're correct, a 5 port is needed since the riser is continuing.

Need to know what's in EMDP-G5-42-MSB-2S1.

One of these might work better: https://commerce.ilsco.com/e2wShopp...k=2100001183:3100012178:3100012237:3100012714
