What must you do prior to performing electrical testing?

Prior to performing electrical testing, it is essential to perform a visual inspection. This step is crucial as it ensures that there are no visible signs of damage or wear on the equipment, wiring, or any other components that could compromise safety or accuracy during testing. A thorough visual inspection helps identify potential hazards, such as frayed wires, corrosion, or loose connections, which could lead to incorrect results or pose safety risks.

While obtaining permission from a supervisor may be part of operational protocols and conducting performance reviews can be important in a broader sense, the immediate precursor to electrical testing focuses on ensuring that the physical condition of the equipment is appropriate for safe and effective testing. Checking weather conditions is generally irrelevant to electrical testing procedures unless specific outdoor conditions might affect equipment performance, which is not a common requirement. Thus, ensuring equipment integrity through visual inspection is foundational to the electrical testing process.
