Tips for North American installs

“Allow negative power”
I only needed this during the install to verify that I didn’t make mistakes in orienting the CTs. After installing the CTs and verifying that the orientation is correct, there is no need for this to be enabled.

Right, my only point is that looking for the little ↺ symbol is the same as looking for a negative number. It means “This number would be negative if you had allow negative values checked”.
