Verdigris applies a technique called single-phase extrapolation, which takes panel 3 phase into a transformer and delivers single-phase AC to the transmitter. While there are advantages to this approach, it can impact the accuracy of measurements by as much as 3%. 

We do not support taking voltage from a different panel. Please work with your solution architect to better determine the best method for installation and what concerns there might be in temporary service disruption.
