Extech 480172 AC Line Splitter

Allows clamp meter to measure AC Current on a 2-wire or 3-wire power cord

This Extech 480172 Line Splitter provides a fast and easy way to “open” standard 120 Volt AC electrical lines, eliminating the need to cut off the plug and separate the conductors. When connected between a 120 Volt AC outlet and a device under test, this splitter separates the hot/live conductor from the neutral and ground, which enables users to measure AC current up to 15 Amp on a two-wire or three-wire lines using a clamp meter. This splitter also features two Voltage Test jacks so that voltage can be measured using a multimeter.

  • Provides easy and safe measurements of current without the need to cut off the plug and separate the conductors
  • Plugging the power connector into the Line Splitter separates the hot/live conductor from the neutral (and ground)
  • Also features voltage check function
