This should officially be part of the safe isolation process ✅ Insulation resistance in a lot of cases can’t be done and that’s alright if ⚡️you word your certificate properly ⚡️understand how to read an MFT ⚡️conduct a clamp test Clamping the lives (earth leakage)- This measures the difference in current between line and neutral Clamping the earth (earth current)- This measures the current flowing through the clamped earth | Scott Little
