Just purchased a new Mastech MS2108 clamp-on meter which measures true RMS and inrush current (not to be confused with the cheaper, less capable MS2108A).

For comparison purposes I also measured the current and inrush current on our microwave inside the house. It measured 13.2 amps with 48 amps of inrush current.

Your measurements sound about normal.
