...The current clamp a lot of people here recommend is the Uni-T ut610e.
It is capable of measuring ac and dc down to 1mA
@ MosherIV: I think you mean the
Unit-T UT210E perhaps?
a nice little unit that does well for AC as well as DC
I recently chose it over the Fluke 368 which imho is a wayyy overpriced (even by Fluke standards
![Shocked :o](https://www.eevblog.com/forum/Smileys/default/shocked.gif)
) one trick pony with limited AC bandwidth
and in my trial case did not really want to read anything 'low' except clean-ish 50hz sine waves
IIRC the Unit-T UT210E is good enough (but not great) for AC leakage issues,
or at the least, leakage differences, once you've got a reference that does not trip RCD/GFCI etc
It shouldn't disappoint, but just make sure you can return it if it does.
@ Kjelt: if you're in a real pinch

there's always the dirty way of butchering the earth ground wire on an extension cord that a member documented with a picture at EEVblog somewhere..
![Confused :-//](https://www.eevblog.com/forum/Smileys/default/confused0024.gif)
,
running that wire (via my suggestion > retractable and joinable? banana plugs, and inline 50 to 100ma fuse please
![Scared :scared:](https://www.eevblog.com/forum/Smileys/default/scared.gif)
) through the mA AC current inputs of the 287,
run power through that jerry rig and plugging in devices to find the nasty/s or what combo/accumulation of devices exceeds 25 to 30mA that causes the tripping
If that fails, it's time to suspect the outlets/wiring and do a moisture hunt around the property
EDIT: now that I'm loaded up with coffee, stand by for some serious revision or partial/total retraction of my blab above

i.e. sometimes it's not that easy or straightforward getting a reading on those elusive AC milliamps for many reasons
