3.0 out of 5 stars Higher price and fewer features than similar designs April 22 2008
By HMMWV - Published on Amazon.com
Like the Elenco ST74 ST74 AC Line Splitter, this product has a X1 and X10 current loop transformer and a line / neutral banana jack for measuring voltage.

You can read my review on the ST74 for the advantage of having a X10 loop to use with your meter, but this design lacks some desirable features found on the ST74.

I should point out that both products insist on hanging from the outlet supplying power. This is fine for a new, high quality outlet, but often problems happen with old, worn out jacks that barely grip a heavy cord. Remember that the outlet must support both these devices and the weight of your amp clamp.

The missing features here are:

1 - there is no banana jack for "EARTH/GROUND". Since outlets can be miswired, or have an open earth connection, this is an important line to be able to probe safely. The ST74 has this jack

2 - the output jack to your appliance is ONLY for the US standard. This is fine most of the time, but on the rare chance you need to test a foreign plug, the "UNIVERSAL" jack on the ST74 will let you plug almost any power cord into it.

3 - Finally the ST-74 costs a little less. I do think this is better built than the ST-74, but that's just from "feel" of the product. Both products "hang" off the power outlet you put them into and lack a 6" or 12" power cord, which would be nice to accommodate inconveniently located outlets or outlets that won't support the extra weight of a current transformer + amp clamp. I would give this 4 stars if it had a power cord and 5 stars if it had a ground jack as well as the line and neutral. I've seen too many worn out power outlets that won't hold onto an adapter plus an amp clamp.

If you don't care to measure ground impedance, don't think you'll ever work on foreign power cord devices, and have some more money, then its fine for you. But the ST-74 still does more for less and is a better value.

1.0 out of 5 stars defective plus they lie about the cable inside. July 23 2011

The outlet on this was defective from day one they had the prong bent wrong on the inside. So I had to open it up and hook up my own 14 gauge wire inside. When I looked at the wire inside i noticed it was only rated for 300 voltes not 600 like it says on the outside. how did this even pass UL listed.

Im sure you it would work fine if you get one that the plug isnt bent.

5.0 out of 5 stars A must have for anyone doing DIAGNOSTICS! Nov. 7 2010
By A. LOCOCO - Published on Amazon.com
Verified Purchase
Sitting in a diagnostics class my instructor was going on about a gizmo he built that seperates the lines so a clamp meter can be effictively used. He claims he built this doo-hickey for about $25. I thought thats great as I pulled this out of my tool bag. It is way smaller and does not look like some mad-scientist made it in his shed. My instructor thought it was nice then asked "what did this fancy thing set you back?" When I told him about $12 everyone was impressed, including him. I have used it a few times in the field and in class to complete assignments but it is way easier than disconnecting and jumping hard-wired equipment that had 2/3c wrapped in the case. Not something I figure I'll use every day but well worth the investment.

1.0 out of 5 stars Defective outlet or poor design Nov. 26 2012
By LLL - Published on Amazon.com
Verified Purchase
The 120 V outlet is either defective or poorly designed (or perhaps both). A standard 3-wire grounded plug only makes contact the last 1/8" of insertion. Any slight movement of the plug breaks the circuit. The connectors for a voltmeter also did not fit properly (way too tight). In the same order I also bought the Amprobe ELS2A splitter. It is much better made and all of the connectors worked well. I returned the Extech unit to Amazon in exchange for another Amprobe unit.

5.0 out of 5 stars Ideal Product for the use intended? July 12 2009

Want to know how many AMPS your 'puter, stero, etc. draw? Buy this tool and use your clamp meter to measure. No cutting or splitting wires, just plug it in to the outlet and plug your device into it!
