MDP switch over, isolated phases

What if we dont attached the pipes to the mdp? If we knock out our holes to 4inch and our pipe is 3 1/2 our cabinet will just be hovering over the pipes. Mdp will be sitting on deep strut basically.

If the metal base completely surrounds only 1 conduit it can cause problems, regardless of how far the metal is from the conduit.
The metal needs to surround all of the conduits.
