The 120A rating gives me plenty of headroom for the main feeder, and the clamp itself feels solid and well-built. Hooked it up to the Pro 3EM in about ten minutes, and the readings match my utility meter within a fraction of a percent.
Went from a 5A clamp to this 120A one and the difference in measurement stability is night and day. The transformer itself feels hefty and the clip-on design makes it easy to retrofit onto existing wires without interrupting power.
Clamped it onto the live line in about ten minutes, and the readings on the Pro 3EM are spot-on compared to my utility meter. The 120A rating gives me plenty of headroom for my subpanel, and the build feels solid enough to leave in the panel long-term.
