500 MCM can carry 380 Amps at 75 degrees C.
To calculate the amp rating for a 2kW fan heater, divide the power rating (2000 watts) by the voltage of your electrical system. For example, in a 120V system, the amp rating would be around 16.67 amps (2000 watts / 120 volts).
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.
No, a breaker needs to be loaded less than 80 percent. As they reach their tripping point they get hot. The circuit rating, breaker and wiring is not designed for 21 amps. The next size would be a 25 to 30 amp breaker that has #10 wire feeding it.

Yes, a relay with a 40 amp rating can be used in a circuit with a 30 amp fuse. The fuse is designed to protect the circuit from overcurrent, while the relay's rating indicates the maximum load it can handle. As long as the total current drawn by the circuit does not exceed the fuse rating, the relay should function properly.
The maximum amp rating for a device designed to handle a 10-2 amp rating is 10 amps.
Yes, you can use a 15 amp outlet on a 20 amp circuit. The outlet's amp rating should not exceed the circuit's amp rating.
The amp rating for 10 wire is typically around 30 amps.
The electrical appliance has a 10-3 amp rating.
The electrical appliance has a 10/3 amp rating.
The amp rating of an 18AWG wire is typically around 16 amps.
500 mcm (or 500kcmil) conductors are used for 400 amp 480v single phase or 3 phase systems. The wire AND THE TERMINALS must be rated for 90o Celsius.
The amp rating of 10AWG wire is typically around 30-40 amps.
The typical amp hour rating of a marine battery is usually between 50 to 200 amp hours.
The amp rating for 10-2 wire is typically around 30 amps.
The amp rating for 10-3 wire is typically around 30 amps.
The amp rating for 10/2 wire is typically around 30 amps.
