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.
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.
The ampacity of an 8 gauge wire at 240 volts would depend on the specific type of wire and the installation conditions. Generally, an 8 gauge wire can safely carry around 40-50 amps of current. It is important to consult the National Electrical Code (NEC) and local regulations for precise guidance.
A 14-gauge wire can typically carry up to 15 amps of current, while a 12-gauge wire can handle up to 20 amps. It's important to follow the manufacturer's guidelines and electrical codes when determining the maximum current for a specific wire 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.
An 8-gauge wire can typically carry around 40-50 amps of current. However, the actual capacity may vary depending on factors such as insulation type, installation method, and ambient temperature. It is always best to consult the National Electrical Code (NEC) or a licensed electrician for specific guidance.
Generally 40 amps continuous or 50 amps surge is safe.

The size of wire needed for a 220v circuit depends on the amperage of the circuit. For a typical 220v circuit at residential settings, a 10-gauge wire size is commonly used for 30 amps, while larger circuits may require 8 or 6-gauge wire for higher amperage ratings. It is important to consult with a licensed electrician to ensure the correct wire size is used for your specific application.
8 gauge wire can typically carry up to 40 amps at 120 volts AC over a distance of 25 feet. However, it is important to consult the specific wire manufacturer's specifications and consider other factors such as temperature, installation conditions, and local electrical codes when determining the ampacity of the wire for a particular application.
A #8 wire with an insulation rating of 75 or 90 degrees C is rated at 45 amps.
60 amps
For a 40 amp circuit, you should use a 8-gauge wire for copper or a 6-gauge wire for aluminum. This will ensure the wire can safely carry the current without overheating. It's important to always consult the National Electrical Code (NEC) or a licensed electrician for specific wiring requirements.
