This line splitter is an auxiliary tool for a clamp ammeter (hereinafter referred to as clamp meter). The internal structure of the line splitter separates the wires into a single conductor passing through the measurement window, and multiplies the current to the measurement window by 10 times. You can measure the single conductor inside the sheathed power cable accurately and conveniently without damaging the clamp meter with the sheathed power cable. Only clamping one of the wires can obtain an accurate current value when using a clamp meter to measure current. Rated for 230V and MAX 15A
