How to Use a Multimeter to Measure Current
Since current is measured inside a circuit, it is strongly advisable NOT to use a multimeter when measuring high-voltage AC current. What you can do is to use a clamp meter to measure AC currents. The meter uses the electromagnetic field of AC current to measure current, and does not need to be in contact with the wire, so it is safe.
