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.

For a 60 amp breaker, you should use a 6-gauge wire for copper or a 4-gauge wire for aluminum to ensure safe and efficient electrical distribution. It is important to follow local electrical codes and regulations when determining the appropriate wire size for a specific amperage.
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
#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.
A #6 copper conductor with an insulation factor of 90 degrees C is rated at 75 amps.
For 6 gauge wire, typically you would use a 60 amp breaker for larger appliances like a dryer or cooktop. However, always consult with a licensed electrician to ensure the proper breaker size for your specific application and local electrical code requirements.
The 225 amps is the secondary output amperage. Look on the machines nameplate to find the input amperage. It is that amperage that is needed to size the feed wire and there the breaker size. When you find that amperage you may want to re question the breaker size.
The amp size of a wire is determined by its gauge, not the number of wires. An 8-gauge wire is typically rated for around 40-60 amps, depending on the type and insulation of the wire.
For a 20 amp breaker, you typically need to use 12-gauge wire. This wire size is capable of handling the current load without overheating or causing a fire hazard. It is important to always follow local electrical codes and regulations when determining wire size for a specific amperage.
A breaker is sized by the conductor that is connected to it but also the load that is connected to the breaker. There are some cases such as motor loads where the breaker has to be 250% of the motors full nameplate amperage.A #6 aluminium conductor with an insulation factor of 90 degrees C is rated for 55 amps.
