GE T8 Fluorescent Ballast - 347V AC | Instant Start

The GE T8 Fluorescent Ballast, model GE332-N-347V (74105), is the component described here. Use this model when the ballast in the fixture is specified for the same lamp type, lamp count and supply. The 3 X F32T8 operating configuration distinguishes this ballast from versions intended for a different lamp count. Its specified starting method is instant start; compare it with the existing circuit rather than relying on the housing dimensions alone. The listed ballast factor is 0.88, which is relevant when comparing the output of the same lamps on different compatible ballasts.

For electrical planning, 347V AC is the stated supply requirement for this model. The listed body dimensions are length 9.50 in., width 1.30 in., height 1.18 in.; use them when checking the available space around the ballast compartment. Follow the wiring diagram for this model when making the replacement connections.

Buying tip: Match the lamp designation, number of lamps and supply voltage to the existing ballast.
