Prior to purchasing the IotaWatt, I’m looking for CT’s that will physically fit into the breaker box.
In the box I have 14 20A breakers and space is very tight.
For size and capacity these look promising, and I’m curious is they have been used with Iotawatt. http://www.echun-elc.com/UploadFiles/2017111814217533.pdf
I have not tried these out. They look suspiciously like the YHDC STC006, which I do not recommend. If space is an issue, consider using solid core CTs. They are not only the lowest cost, they perform better than the split-core equivalents.
