Con Ed requirement

Someone told me that NY Con Edison requires the same number of sets of conductors on the line side and the load side of the meter.


However, I cannot find any code or Con Edison document that mentions this requirement.


Has anyone heard about this?
 
It is not the case, because the conductors on the utility side of the meter are chosen by Con Ed based on their standards, and on the load side they are based on the NEC, which are typically larger (lower ampacity).

No, I mean in the building, in the main electrical room. For example, if three sets of 600 kcmil copper conductors are connected to the line side of a 1200 A CT, you must also use three sets of 600 kcmil copper conductors on the load side. You cannot use four sets of 350 kcmil copper.

I don’t know if this is a Con Edison requirement or if it depends on the Con Edison inspector
