CT clamp for eSpaMax.

Hello, what rating CT clamp is recommended for power monitoring with the eSpaMax 3.5mm jack? Do you recommend a particular tested clamp?

In not sure recommend is the right word, as i don't want to be held responsible for a broken spa. But i am using this one:
Non-invasive AC current sensor Split Core Current Transformer

You want one that is rated just above the spa breaker rating. E.g. I have a 15A breaker, so the 20A1V.

Thanks. My spa has a 32a breaker so the closest I can find is a 50a. :)
