Final answer:
The inspection of an electrical system should begin at the voltage source, where the neutral wire is grounded and the circuit breaker or fuse is located.
Step-by-step explanation:
The initiating point of an inspection of the electrical system in a property should be the voltage source. This is where the neutral wire is connected to the earth, setting it to zero volts and providing an alternative current return path through the earth. This part of the system also houses the circuit breaker or fuse that protects against thermal overload, placed in series on the active (live/hot) wire. Therefore, an understanding of the condition and functionality of these components is crucial before proceeding to other parts of the electrical system.
