Is this a safe way to isolate test equipment
I decided its best to purchase an inverter and a few 48v bricks (without ground pin) to power bench dmm & scope with inverter I will likely stick a copper pipe a few feet long into the ground and fill it with water for grounding. Inverters are the most economical option and no need for diff probes or heavy transformers. Inverter can be really small (less than 150W) because scope & meters use about ~30W each. I have power supply and it wont be isolated, but I won't use its ground. Is there a dangerous flaw to this isolation method?
