As a computer hardware enthusiast and a fresh DIY-er (just moved into my own house), I've purchased a digital clamp multimeter. Learned the hard way that in order to utilize the clamp to measure current, the supply line needs to be split.
Rather build a line splitter instead of settling for a product. The clamp has a 20A limit - research indicates a 12/2 wire with an equally rated male-female power plug should suffice.
Has anyone created a line splitter before - Any precautions/best practices? Thanks
