CT cabinet with only 2 CT's in it - 02/06/09 09:46 PM
I found this photo on the internet and am wondering why 2 things.
1. Why is there only 2 CT's, with the B phase unmetered?
2. If the color code is right, this is a 208Y/120V 4 wire system. Where is the grounded(neutral) conductor? Isn't this a violation of 250.24(C)?
I have never seen a CT cabinet that didnt have a CT for each phase. Maybe someone could steer me in the right direction.
