Hey candlelamp6,
For bus-bar mains like these – we generally recommend using the Flexible Sensors to capture those since the default 200A CT’s usually won’t fit. If you want to try and fit the default CT’s on those bars, I’d probably try to slide the top part of the CT (thinner) underneath and around the back of the bus-bar, then clamping the bottom part of the CT over the front of the bar and into place. A bit hard to tell just from the pic if that’d work, but that’d probably be the easiest way to see if they’d fit.
We’ve been out of inventory of the Flexible Sensors recently (apologies for those who’ve been looking/waiting) – however we just got some back in stock today. Trying to get the shop page updated w/ a listing very shortly, hopefully by the end of today but might be early Monday morning when that goes live. Once those are available, you can pick up a pair of those and you should be good to go.
