Bill,

From the pic and descripion, it looks as though yours is a little more versatile with the removable clip leads.

Al,

The one I have is similar in appearance with the two positions for x1 and x10, but it has a fixed 2 ft. cable to a molded plug/receptacle combination (standard U.S. NEMA 5-15).

I tried the Simpson website - www.simpsonelectric.com - but I couldn't find it listed. In the paper catalog they call it a "Model 151-2 Line Splitter," part #00544.

I got mine along with the Simpson 150-2 "AC Amp Clamp" by mail order some years ago.

I see you're in Chandler, AZ. I bought some Simpson stuff mail-order from Jensen Tools in Phoenix, not too far away from you. I don't think they carry all the Simpson range, but it might be worth a look.
