For runs under 75ft 4 gauge wire is recommended. For runs over 75ft consult a wire size calculator. Remember that the total circuit length is twice your run. (length of Hot + length of Neutral) Don't divide your run length by 2.

A table in the electrical code book states what size cable or wire is allowed to carry a specific amperage. A #6 copper wire wire with an insulation rating of 75 or 90 degrees C is rated at 65 and 65 amps respectively. A wire is only legally allowed to be loaded to 80% capacity. If the load needs the full 60 amps then the next wire size up must be used. A #4 copper wire with an insulation rating of 75 and 90 degrees C is rated at 85 and 85 amps respectively. De-rating this wire to 80% capacity will allow 85 x .8 = 68 amps.

It depends on the ambient temperature and type of wire but generally the answer is 6 AWG

A common wire size for a 220V, 60A circuit is AWG-6.

#6 wire can take 60 amps up to a distance of 150 ft (240 v system) or 125 ft (120 v system.

The wire size should be increased to #4 for a distance up to 300 ft.

#6 RW90 copper or #4 aluminium. Keep in mind that the conductors can only be loaded contineous to 80%. 60 x .8 = 48 amps.
