what to do when you have no more spaces

[hot wire]

I looked at this job at a church there adding some double wides trailors for class room space 1 trailor has been set for about a year that one has 2 100 amp panels fed from a 400 amp service . this new trailor has 2 200 amp panels. I know this trailor doesnt have 200 amps in the whole trailor. But the probem is where the 400 amp service is there is no room 1 panel has 200 amp main 4 ckt panel which is feeding trailor 2nd 200 panel 24 ckt panel has 3 empty spaces. is it ok to set a though on a service cable and feed both trailors off 200 amps 2 100 panels 2 200 off 200 amps doesnt sound good i need to check load with amp probe .The biggest thing on the trailor is the heat &air unit on the side of it 2 pole 60 any body know what else to do

I am confused by your setup but you can have 6 200 amp panels fed from a 100 amp panel as long as the load does not exceed the 100 amp rating of the panel.

You definately need to do a calculation.

The amp rating of the panels means nothing. You can feed a 200A panel from a 30A circuit breaker. Its the load calc that counts. We often use a 200a panel to get the 42 spaces.
