   There are now clamp on hall effect AC/DC curent sensors.  These
   are  generally expensive and subject to zero drift on DC measurements.

For those that are interested in such things, I'm very happy with the
Wavetek CT-237.  I believe it is the hall effect sensor with the best
resolution (30mA).  It has scales for 20 and 200A.  I paid a little
over $200 for mine.
