What is the first step when approaching the rectifier case?

Check the rectifier for AC case to ground voltage
Test the DC output voltage
Inspect the connections
Look for signs of physical damage

The correct answer is: Check the rectifier for AC case to ground voltage

The first step when approaching the rectifier case is to check the rectifier for AC case to ground voltage. This is crucial because it allows you to determine if there is a potential electrical hazard that could pose a risk during further testing. By measuring the AC voltage, you can identify whether the rectifier is functioning within safe limits and if there's any stray AC voltage present that could interfere with DC output readings. This step is important as safety must always be prioritized before any testing procedures. Once you confirm that there are no dangerous AC voltages present, you can proceed confidently with your testing procedures for DC output and other assessments. Detecting AC voltages early on can potentially prevent electric shock or injury, making it a foundational safety protocol in working with rectifiers.
