Split Core or Clamp On

The bundle offers both Split Core and Clamp On for the mains?

Is there a difference in accuracy or any other features I should consider when ordering?

The advantage of the clamp-on is easier installation. The split-core are slightly better on paper in that they are 0.5% vs 1% for the clamps, but both give excellent results.

Thanks. What is the best CT if I want to monitor more than 1 circuit with one CT?

That depends on total Amps expected and total wire bundle size. The options are:

400A x 36mm
200A x 25mm
100A x 16mm
50A x 10mm

I have 3 240 circuits I would like to monitor, pool filter, air handler and ac compressor. Can those be handled with one CT or should they have two?

That’s all explained here.
