Description

The MS5902RTF is a circuit breaker finder and socket tester from Mastech, designed for electrical systems in the United States and Canada that operate on 120V AC. The "F" in the model number designates it as the version for 120V circuits, as opposed to the "D" or "E" versions for 230V systems.

Key Features
  • Indicators: Audible (buzzer) and visual (LED) signals for both the socket tester and breaker finder functions.
  • Automatic sensitivity adjustment: The receiver automatically adjusts its sensitivity to quickly find the correct circuit breaker or fuse.
  • Built-in flashlight: Aids in using the device in dark environments, such as inside an electrical panel.
  • Low battery warning: An LED indicator on the receiver warns the user when the 9V battery needs to be replaced.
