    Are you doing a mast service on an outbuilding? Or the main service?

    The utility usually provides the aerial cable.

    We have a resident expert here that lives in NY, perhaps he can help with the NY question, other than that I would suggest you check with the local inspector.

    Reduced neutral is allowed by Code when the calculations are performed for interior feeders. Service entrances laterals, esp by the utility, is done often without calc done.

    Torque values are given on the labels of equipment, for the mechanical connectors, or lugs. Not by the wire. Need to look up the specs of the meter trim/socket you will be using.
