Mains Current Montoring

["Dan Lowe" <ukha@xxxxxxxxxxxxx>]

Hi All

After seeing Mark's link (Large Building Control), and the fancy graphs on
those tools to see mains load, it got me thinking.  Has anyone seen a
device
which I speculate may have a CT and something useful like an ethernet port
which I can clamp around the mains incoming without interfering with it,
and
then pull off my load in amps?  It's what you see on fancy electricity
meters in new houses where you can cycle the options and see load and what
not.
