A #8 copper conductor with an insulation factor of 60 degrees C is rated at 40 amps, insulation factor of 75 or 90 degrees C is rated at 45 amps.
If the breakers rating is 90 degrees C then the amperage can be boosted for 60 degree wire to 40 amps, 75 degree C wire to 50 amps and 90 degree C wire to55 amps.
A #8 is rated at 40 amps but code only allows 80% capacity. 80% of 40 = 32 amps continuous
#8 Copper Wire is rated at 40 amps when you use Wire types TW, UF listed at 60 Degrees Celsius, 50amps at wire thats rated at 75 Degrees Celsius (TYPES RHW, THHW, THW, THWN, XHHW, USE, and ZW) and at 55 amps at 90 Degrees Celsius (TYPES TBS, SA, SIS, FEP, FEPB, MI, RHH, RHW-2, THHN, THHW, THW-2, THWN-2, USE-2, XHH, XHHW, XHHW-2, ZW-2. The degrees are what the insulation is rated at.
24 Amps.

A #8 copper conductor with an insulation factor of 75 or 90 degrees C are both rated at 45 amps.
#8 copper is rated for 45 amps R90 degree insulation.
A #8 copper wire insulation rating of 90 degrees C is rated at 45 amps. At 75 C = 45 amps, at 60 C = 40 amps.
A #8 copper conductor with an insulation factor of 90 degrees C is rated at 40 amps.

In cooper electrical wire, gauge 8 means the wire size assigned by the American Wire Gauge (AWG) system. That is why you always will hear about AWG WIRE, it's not the type of wire is the gauge that we are talking about. A gauge 8 wire will be used for connections requiring from 40-45 amps to a maximum of 73 amps. (24 for power transmission). Diameter of an 8 AWG wire is 0.12849 inches. 8 AWG is solid, not stranded.
5 amps
Wire is not sized by voltage. It is sized by current measured in amps. Some common copper wire sizes and their current capacities are: 15 amps -- 14 gauge wire 20 amps -- 12 gauge wire 30 amps -- 10 gauge wire 40 amps -- 8 gauge wire
Generally 40 amps continuous or 50 amps surge is safe.
A #8 copper wire with an insulation rated at 75 or 90 degrees C is rated at 45 amps.
A #8 copper wire with an insulation rating of 90 degrees C is rated at 45 amps.

A #8 copper wire with an insulation factor of 75 or 90 degrees C is rated at 45 amps.
A #8 copper wire with an insulation factor of 75 or 90 degrees C has an ampacity of 45 amps. A #8 wire with an insulation factor of 60 degrees C has an ampacity of 40 amps.
I would recommend #8 AWG for any residential wiring application for 40A.
A #8 wire with an insulation rating of 75 or 90 degrees C is rated at 45 amps.
60 amps
I am assuming that this is a one and a half HP motor. To wire a 120V 20A motor the electrical code states that the conductor has to be 125% of the motor's full load amps. This equals 25 amps. There is no wire rated at 25 amps so the next size up is 30 amps. A #10 copper wire with an insulation factor of 60, 75 and 90 degrees C is rated at 30 amps. To carry this to a conclusion This #10 wire should be protected by either 60 amp non time delay fuses or 35 amp time delay fuses or a two pole 50 amp breaker.
