A #6 copper conductor with an insulation factor of 75 or 90 degrees C are both rated for 65 amps.
The ampacity or amp rating of all wire is rated by the size of the wire. NM (non-metallic sheathing) wire is no different. In household wiring 14 gauge wire must go on a 15 amp breaker/ 12 gauge goes on a 20 A and 10 gauge goes on a 30 Amp.

A wire gauge is a number that indicates how thick the wire is. A larger gauge number means a thinner wire. Gauge and diameter can be linked by looking up wire tables.
The current (amp) capability is determined by the wire size in gauge, rather than the voltage rating stamped on the insulation. The most basic rating is 20 Amps for 12 gauge and 15 Amps for 14 gauge wire; however, it can get more complex than that for long runs of wire or for wires run through conduit with other wires. Hire an electrician if this sounds bewildering.
For low voltage wiring, typically smaller gauge wire is used, such as 18 or 20 gauge. The specific gauge will depend on the current requirements of the circuit and the distance the wire needs to run. It's important to consult the manufacturer's recommendations or local building codes to determine the appropriate wire gauge for your application.
The NEC wire gauge chart provides information on the recommended wire sizes for different electrical applications based on factors such as current capacity, voltage rating, and insulation type.
The maximum current rating for a 20A wire gauge is 20 amperes.
The amp rating for 18 gauge wire is typically around 16 amps.
The amp rating for an 18 gauge wire is typically around 16 amps.
The ampacity rating for 18 gauge wire is typically around 16 amperes.
The amp rating for 14 gauge wire is typically around 15 to 20 amps.
The amp rating for a 4 gauge wire is typically around 100-150 amps.
The amp rating for a 3 gauge wire is typically around 85-100 amps.
The recommended amp rating for 18 gauge wire is around 16 amps.
The maximum amperage rating for 18 gauge wire is typically around 16 amps.
The ampacity or amp rating of all wire is rated by the size of the wire. NM (non-metallic sheathing) wire is no different. In household wiring 14 gauge wire must go on a 15 amp breaker/ 12 gauge goes on a 20 A and 10 gauge goes on a 30 Amp.
The recommended gauge for 12-2 low voltage wire in outdoor lighting installations is typically 12 or 14 gauge wire.
