General InformationThe complete family of transformers from GE provide quiet,reliable transformer operation.All of the dry-type transformers through 1,000 kVA are UL listedunder the requirements of Standard 506 and 1561. In addition,each transformer meets the requirements of NEMA ST-20,1992.Type QB, QMS, and QMS 3 models are C-UL listed.General-purpose transformers are rated 600 Volts and below forsupplying appliance, lighting, and power loads from electricaldistribution systems. Standard distribution voltages are 600, 480,and 240 Volts; standard load voltages are 480, 240, 208, and 120Volts. The transformer is used to obtain the load voltage from thedistribution voltage. Since no vaults are required for installation,these transformers can be located right at the load to provide thecorrect voltage for the application. This eliminates the need forlong, costly, low-voltage feeders.

ConstructionTypes QB, QMS, and QMS 3Core and coils are contained within a NEMA 3R nonventilatedweatherproof enclosure. Type QB, QMS, and QMS 3 units featureencapsulated core and coils.Type QLUnits are enclosed in a NEMA 2 drip-proof metal enclosure withnatural-draft ventilation. Core-and-coil assembly is mounted onrubber isolation pads to reduce noise. Weathershield kits areavailable for conversion to a NEMA 3R enclosure suitable foroutdoor service.

How to Select• Establish phase and frequency• Determine the primary voltage—the voltage presently available• Determine the secondary voltage—the voltage needed at the

load• Determine the kVA load, allowing room for expansion• Using the facts determined in the four steps, locate the

transformer model in the listings on the following pages.

Voltage Tap ArrangementTransformer taps compensate for high or low line voltages.Standard NEMA, ANSI three-phase taps are two 5 percent tapsbelow normal on transformers smaller than 30 kVA. Thisarrangement provides a 10 percent range of tap voltageadjustment.

Most standard QL units rated 15 through 500 kVA have availablesix universal voltage taps—four 21/2 percent below normal, andtwo 21/2 percent above normal. This arrangement provides a 15percent range of tap voltage adjustment.

All standard, general-purpose, GE transformers meet allapplicable NEMA, ANSI, UL, and IEEE standards.

The design life of transformers having different insulation systemsis the same, since the allowable temperature rise of an insulationmaterial system is predicated on a specified life for all insulation.The lower temperature systems are designed for the same life ashigher temperature systems.

TerminationImproved termination spacing and wiring compartment roomgives greater flexibility in selecting various UL listed connectors foreither copper or aluminum cable. A listing of suitable connectorsis packaged with each GE transformer.
