Product Description

AC Line Splitter

This Extech Line Splitter provides a fast and easy way to “open” standard 120V AC electrical lines, eliminating the need to cut off the plug and separate the conductors.

How it Works

When connected between a 120V 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 amps on a two-wire or three-wire lines — using a clamp meter.

Dual Readings

The 480172 provides two openings — one opening provides one-to-one current measurements, and the other provides times-ten (X10) readings so that low-current readings will display with higher resolution on a clamp meter.

Voltage Checker

This splitter also features two Voltage Test jacks so that voltage can be measured using a multimeter.

Very usefull to measure current of pretty much everything that operates under 120VAC. Still unsure though about the 10x accuracy. Did some tests with different clamp meters and didn't quite get the 10x value when compared to the 1x. Perhaps the reading error is induced by the meter's range itself, the positionning of the clamp, or whatever else. For general troubleshooting purposes and reasonnable accuracy, it does the trick.

It's a nice solid AC Line Splitter. Brightly coloured to fit easily see in my bag. Only issue is I have a micro clamp meter that goes to down to a 2A range and the clams have to be aligned perfectly to fit over this. It's slightly larger than the last one I had. But that's not a good enough reason to complain.

This is a wonderful tool for anyone seeking to find the volt / amp rating on any plug in device. Which combined with a clamp meter it works like a charm to isolate the hot conductor. It's great when doing a power audit of devices in a house. This is very useful when designing a backup solar power supply drawing on batteries. Knowing the power demand of any given device is important when scaling the system, or figuring out circuits.

The voltage test points come in handy, and the 10x current loop is good for low power equipment to be tested

Great price with great build quality. I trust this line splitter and would recommend it to anyone with a clamp meter (to measure AC amps) or multimeter (to measure AC volts).
