The answer to 'troubleshooting vs' is that troubleshooting and testing are both important electrical maintenance tasks, but they serve different purposes. Troubleshooting is the process of identifying and resolving electrical issues or problems, while testing is the systematic evaluation of an electrical system or component to ensure it is functioning properly.
Troubleshooting typically involves using a multimeter or other diagnostic tools to isolate the source of an electrical problem, such as a blown fuse, faulty wiring, or malfunctioning appliance. Testing, on the other hand, is often done proactively to verify the safety and performance of an electrical system, even if no issues are currently present.
