For calculation, Divide the power (watts) by the voltage (volts). For example, a 4,500-watt water heater with a voltage of 230 volts, it will get the current at 19.56 amps.

2. Select the size of a circuit breaker with a suction cup.

choose a circuit breaker with the best electric shock and leakage protection. The size of the circuit breaker should be more than the current. For example, in the first step we got the current at 19.56 amps, that means The circuit breaker used should be 20 amps or more.

choose a wire which can bear with the electric current more than a breaker for Prevent The wiring burnt. For example, the circuit breaker is rated at 20 amps, so the wire should be a size 4 with a current of 28 amps.

4. Grounding wire

Choose a size smaller than the wire. For example, we get a size of 4, the electric current is 28 amps, so a suitable grounding wire is 2.5 with 21 amps.
