Types D-14, D-15, I-18 (1928 to 1936)	Back	Up	Next
Shortly after GE brought out the new I-16 singlephase meter, 3 new polyphase models were introduced that had the same improvements that were incorporated in the I-16. As other companies were doing at this time, the terminals were moved from the sides to the bottom. The I-18 was a version of the D-14 developed for 3-wire network service and had a singlephase terminal block. The D-15 was the 3-stator version of the D-14.
