I've never seen any cut sheet that explained the physics of E & B fields.
I was not asking for this nor would I expect it.
“Failure to install CT's in the correct orientation and on the correct phase will lead to inaccurate meter readings...”
A warning about incorrect readings would not normally mean be construed to be a warning about equipment failure due to overheating.
I asked for installation instructions from any CT manufacturer that provided a warning that CTs should not be mounted 'near' a 90² turn in the conductor.
Your reply was that this is a topic that is evidently only presented in the deepest E & B field theory discussions.
The CT's that lack shielding are plainly dimensioned for plain vanilla bus bars – rising vertically – in CT sections.
Your lack of field experience (outside the world of utilities or academia) is very evident. The CTs I used as an example are intended to be mounted around the cables in the wiring gutter of panelboards.
