Service Disconnect

[Spartaace1]

Hello,

I have a 200 amp service on a double wide mobile that was installed with 2 - 200 amp disconnects installed in line for additional space. The have 4/0 aluminum in the mast to a 200 amp meter / disconnect combo then from the feed through lugs, they go to the second 200 amp 20 circuit disconnect.  Does 230.80 apply? Does the mast need to be sized for 400 amp?

Thanks

I'm having a hard time understanding the set up. Do you have a picture? 

It sounds like you have a 200-amp meter/main and a 200-amp sub panel immediatly after it. That's a very common set up for manufactured homes. If I'm describing it correctly, then it's just a 200-amp service - nothing needs to be sized for 400 amps.
