What is the first step in troubleshooting a short circuit?

Turning off the power and following safety precautions is essential when troubleshooting a short circuit. This step ensures the safety of the technician and prevents any further damage to the electrical system or potential injury. Safety is prioritized at the outset because working on live circuits can lead to electric shock, which could have severe consequences.

After power is turned off, the technician can proceed to other steps such as locating the source of the circuit, checking for physical damage, or testing the circuit with a multimeter, but these actions must always be done with the power off to ensure personal safety and effective troubleshooting. This foundational step lays the groundwork for a thorough and safe investigation of the issue, underscoring the importance of proper safety protocols in electrical work.
