| In keeping with industry advances, GE revised the I-14 to add improvements that allowed accurate operation over a wide range of temperatures and loads. The cover was redesigned to attach to the base using a metal rim with bayonets, eliminating the wing nuts and studs formerly used to secure the cover.
The terminal cover still had a corner pivot as on the I-14 but it could now be taken off if needed.
In order to improve the meter's accuracy over a wider range of loads, the speed was reduced by half to 16 2/3 RPM. The earliest I-16s have a small nameplate very similar to the I-14's. There are three base sizes for the I-16, depending on capacity: one for 5 and 10 amp, a second one for the 15 through 50 amp ratings, and a special one for 100 amp 2-wire services. |
