I don't know why it's not listed as 60A max, but my own internal
logic would ask why it should be. The only benefit I could see for
using smaller

Wrenches,
On an upcoming job we have a Xantrex XW4548 interconnecting with a 200A
service, and I'd very much appreciate some advice if y'all are willing.
Since the inverter output OCPD is required to be 60A we are looking at a
supply side connection, and I have two questions:

Hi Garrison,
In my opinion you only need to size the conductors to the overcurrent
protection. Bill Brooks addressed a similar question of mine a few months

There is an exception in NEC2011 regarding the point of connection. This
may not apply, but you could avoid the supply side. 4500W / 240V = 18.75 x
1.25 = 23.4A, well under the 120% rule. reference 705.12(D)(2)
