The condensing unit rating plate and the tables of "Physical and Electrical Specifications / Outdoor

Units" (Table 1 and 2) provide pertinent data necessary for the selection of proper size electrical service

and over-current protection devices.

Table 4 provides data on the minimum copper wire size as a function of supply wire length and circuit

ampacity.
