obviously the intent is to prevent the raceway from becoming a source of water and corrosion in the panel. By not allowing the raceway from entering the panel directly from underground it adds a fitting to permit draining any condensate away from the panel. In BC we encourage contractors to mount meters outside the wall so the underground raceway enters outside the wall. this does a lot to prevent water from entering panels as any water would drain from the meter base outside the wall. Cables like teck or AC90 should be more immune from transporting water from outside to inside but I have seen water go down a cable too. In terms of what is required to avoid water entry where a raceway goes through a wall underground. Each site has it's own solution and if you have a challenge a discussion with your inspector might save time and money.
