Under strict safety guidelines which of the following should be used to discharge capacitors before working on de-energized circuits? hot stick phasing tester test instrument salety discharge probe

## Step 1<br />The problem is asking us to identify the correct tool to use when discharging capacitors before working on de-energized circuits. The options provided are: hot stick, phasing tester, test instrument, and safety discharge probe.<br /><br />## Step 2<br />We need to understand the function of each tool. A hot stick is used to safely remove live parts from the circuit. A phasing tester is used to determine the phase of a circuit. A test instrument is a general term for any device used to test electrical circuits.<br /><br />## Step 3<br />The safety discharge probe is specifically designed to safely discharge capacitors. It is used to safely discharge capacitors before working on de-energized circuits. This tool is designed to safely discharge capacitors, which can be dangerous if not done correctly.
