Any Problem running Wire thru 2 panels ??

[AP514]

I want to run wire from my Manual Standby Gen Switch to the second Panel(main Panel). This would take Wires thru the Panel in between.

Are there any Code troubles I might run into ??

The wires going thru into the second panel will be a #10 Ground, #10 Neutral and 2-#8 wires.
Conduit will be 1" and a 3/4"..SEE PIC

No problem going through the panel. I question why the reduced neutral?

Have you considered using the gutter below instead?

and yeah whats with the reduced neutral? What are these wires for?

Can't run anything in that gutter w/ unfused SE conductors.

Which code is that?

Looks like someone already did what with the conduit under the left panel.

Well, Actually the GENERATOR Manual Transfer Switch has a 30Amp Double Pole C/B and 4 single 20Amp.
The wires I want to connect the 30Amp to are #8 gauge and I think stock Wires will be too short. So, I figured I would stay with that gauge wire when I change them out of the Switch.( about a 2-3ft run )
I have Not actually received the Switch yet so, I do not know for Sure. I figured the 30Amp C/B would have #10 wire for the Neutral. Just getting My Ducks in a Row for when it Shows up.
Note: All the wires for the 20Amp C/B's will be going into the 1st panel then to a inside panel in House. Only the #30Amp wires and the Neutral and Ground will go to the 2nd outside panel. the 2nd Panel (Big one next to meter) is my Main Bonded Panel.
Also if I go in the gutter I fear ALL the wires will be too short.
