ECS10-50 vs AcuCT-H040-50

Hi all. Sorry if this has been addressed elsewhere, tried searching but couldn’t find anything useful.

What is the difference between these two products? ECS10-50 vs AcuCT-H040-50

My Mom has a system and is wanting to monitor a few more 20a circuits. They’re both split core, 50a, $12, no reviews, and neither of us can determine which one to pick.


These are basically equivalent. The political, economic and medical situation early this year prompted a switch in supplier. The AccuCTs are origin Canada.

More substantially:

The AccuCT is 0.5% and the ECS is 1% accuracy.

Both are UR listed but the ECS is also marked CE for the EU. NewAccus will have the CE.
