The results I was able to find are not promising. The best I could come up with is to make use of this and some cobbling: https://moderndevice.com/new-products/current-sensor/ <https://moderndevice.com/new-products/current-sensor/> I have had good luck with other items from Modern Device, but I have not played with this one. It can be purchased here: https://moderndevice.com/product/current-sensor/ <https://moderndevice.com/product/current-sensor/> for $18. Not responsive to your query, but something I thought you might also find of interest: http://ipo.lbl.gov/wp-content/uploads/sites/8/2014/12/3165pub2.pdf <http://ipo.lbl.gov/wp-content/uploads/sites/8/2014/12/3165pub2.pdf> Owen

Hi folks,

I own a Megger MMC850 which will read amps in a multi-core cable, such as the 10 gauge SEOOW cable one often finds feeding rack PDUs.

Datasheet here: http://www.mouser.com/ds/2/263/MMC850_DS_en_V02-15853.pdf

Apparently they've been discontinued. Pity.

Anyone know of a suitable replacement? I need more.
