There were some AIU's with 10A relays, but there were also some with 5A relays. As I recall, MTH rated the box at 4 amps. Remember, even though they added 10A relays, the board layout is still the same. For 1 oz copper traces, to support 10 amps, the traces need to be almost .2" wide, and for internal layers they would have to be almost half an inch wide! I suspect there is a lot more than just the relays that figure into the power rating.
