What size quadplex should be used for an overhead line for 200 A. ? Table 310-17 says 1/0 for 90ºC wire if it qualifies, and that seems to be the size that the PoCo uses.

This is for a dairy barn on the load side of the disco.

Also, the pole that will have the tap is only triplex, Bond the Neutral and Ground at the pole where the tap is made, or? It may be upgraded in the future.

Thanks
