I have a 200 amp meter base disconnect combo unit and I have 2 100 amp panel ran from the secondary spots on my disconnect combo unit. there is no panel hooked to the main 200 amp breaker on the combo unit just 2 100 amp double pole breakers on the secondary part. I want to run a 60 amp 240 volt power panel to my garage. what does the code say about doing this? I was going to run aluminum 4 conductor URD mobile home feed in 2" pic from the house to the garage which is about 80 feet from the house.

You would have to run 200A wire if using the feed through lugs, that or use the tap rules.
 
URD tends to be a generic description for UG conductor, its not allowed in a building as its not listed. Some URD is dual listed as USE.
 
Usually those combos have six spaces, and you are using four. Should be able to add a 60. If not, as others have said, use the tap rule, and add a 60 amp disconnect below and use the 200 amp lugs.
 
Some meter main combos have 20 or more slots. You can install as many subpanels off the meter main as you want as long as each is on their own breaker. The total load of those subpanels needs to be considered of course.

If he is describing what I think he is, it probably has a 200 amp main breaker and maybe up to 8 spaces for plug on branch breakers of up to 100 or 125 amps, and likely 200 amp sub feed lugs at the bottom end of the bus bars.

If so could plug on a 60 amp breaker to feed the garage if there is still available spaces or can land his conductors on the sub feed lugs and use the outdoor feeder tap of unlimited length rule to supply the garage presuming it is supplying a separate structure.

That’s what I’m thinking, I just put in a GE meter/combo, and it has six full size spaces, with the sub feed lugs to the left and right. The OP hasn’t returned to comment on what is there. Looks like another disappearing poster.
