200-amp Current Transformer source on Ebay

[ICPete]

I finally found a source for a current transformer rated for 200 amps and having the proper output:

YHDC SCT-019TS

The output of this component is 33 mA max at 200 amps input current, so it's perfect for the CircuitSetup 6-channel monitor.
It doesn't come with a plug, so you'll need to purchase a 3.5mm audio plug.

I just bought the last four of these that I found on Amazon (sorry!):

Amazon listing for SCT-019TS
[Note that the Amazon vendor is also shipping from China, and the Ebay vendor lists a somewhat faster delivery time to the US. The price was about the same from both sources.]

I needed to measure the 200-amp main breaker current at two places: at my service entrance panel and at my Protected Load Panel ("PLP", for a battery-backed-up photovoltaic system).

This SCT-019TS is openable to install it around the wire, but rather than being split and hinged, it has a small removable section of the core. I haven't received these yet, but when I do I'll upload some photos and describe my experience installing them. They are about 2-inches square, so maybe a bit more compact than the SCT-024 size sensor, yet still their opening is 19mm. For reference, THHN copper wire in 2/0 AWG is about 13mm diameter, and 4/0 AWG is about 16mm diameter. I have the latter at my PLP, so the 19mm opening should be fine.

Glad you found one that will work! Make sure to calibrate to the meter. These look very similar to some Magnalab CTs that I picked up early on (except they were voltage output).
