Customer Reviews (4.7 / 5 · 15 reviews)

Henry ★★★★★

The clamp fits snugly around my 400A busbar and the readings on the dashboard match my utility meter within half a percent. I’ve had it running for two weeks now, and it hasn’t drifted once.

Richard ★★★★★

Setup took maybe ten minutes and the readings have been spot-on against my utility meter so far. The clamp locks firmly without any wobble, which gives me confidence it'll stay put for the long haul.

William V. ★★★★★

Wired these into my panel for a sub-metering project and the 400A rating gives me plenty of headroom on the main feed. The clamp fits snugly around the conductor and the readings on the Shelly system have been stable and consistent all week.
