What must you verify about the phasing meter and live line tools before testing?

• A. They have passed a visual inspection.
• B. They are rated for the voltage being tested.
• C. They are the most expensive tools.
• D. They are battery-powered only.

Answer: (B)

Before testing, you must verify that the phasing meter and live-line tools are rated for the voltage you will test. This rating confirms the insulation and tools are capable of safely withstanding the electrical stresses and any potential voltage spikes that could occur during operation.

To check this, look at the tool’s markings or the manufacturer’s specifications and confirm the voltage range or category rating matches or exceeds the system voltage. Also ensure the tools and test leads are appropriate for the test environment and in good condition.

Visual inspection is important but does not guarantee suitability for the voltage, and other factors like price or being battery-powered do not determine if the tool can safely handle the testing voltage.
