What is an important feature of an amp meter when used in lineman work?

An amp meter, or ammeter, is crucial for linemen as it specifically measures the amount of electric current flowing through a circuit. This function is essential in ensuring that the current is at safe levels and within the operating limits of electrical equipment and systems. By tracking the current, linemen can troubleshoot issues, monitor system performance, and make necessary adjustments to maintain safety and efficiency in electrical installations.

The ability to measure current allows linemen to identify overloads, which can lead to overheating and potential hazards. They can also use this information to balance loads across different phases in a three-phase system. Understanding the current flow is fundamental to maintaining system integrity and safety.
