Let’s say you want to measure the AC current draw of a tool or device. How do you do this without cutting up the cord and wire? With a clamp meter or fork meter of course!
But what do you do if the conductors are all bundled together inside an insulated cord? You use an AC line splitter.
An AC line splitter does exactly what you think – it bridges between a 2-wire or 3-wire power cord and a standard AC outlet, to allow for accurate current measurements with a clamp meter. With a line splitter, the power cord and plug remain intact.
This Extech 480172 line splitter features a 3-prong plug, 3-prong receptacle, and both 1X and 10X clamp positions. The 10X measurement loop should come in handy if your multimeter or clamp meter isn’t sensitive enough to accurately measure small currents with high enough resolution.
The line splitter also features two holes that can be used with a standard meter for voltage measurements.
Input: 120V 50/60 Hz, 15A Max current.

There are a number of AC line splitters around this price range (via Amazon, as I could not find one locally), and I opted for the Extech as it’s a brand I am familiar and comfortable with. My order is due to arrive later this week. I don’t think this type of accessory warrants a review, but if anyone is interested, let me know and I’ll get right on it.
