The amp rating of a 500 MCM (thousand circular mil) cable can vary depending on the insulation type and installation conditions. Generally, a rough estimate for a 500 MCM cable with THHN insulation in a typical installation would be around 380-400 amps. However, it is recommended to consult the manufacturer's specifications or a qualified electrician to determine the exact ampacity for a specific application.
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 amp rating of NM (Non-Metallic) wire varies depending on the gauge of the wire. For example, a 14-gauge NM wire typically has an amp rating of 15 amps, while a 12-gauge NM wire has an amp rating of 20 amps. It is important to consult local building codes and regulations to determine the appropriate wire gauge and amp rating for specific applications.
No, it is not safe to use a 20 amp breaker for a heater with a 21 amp rating. The breaker should be rated at least equal to or higher than the amp rating of the appliance to prevent overheating and potential fire hazards. It is recommended to use a 25 amp breaker for a 21 amp heater.

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.
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.

yes two fuses in parallel will increase the amp rating but its not a good practice try to get the proper fuse!
