The complete family of transformers from GE provide quiet, reliable transformer operation. All of the dry type transformers through 1000 kVA are UL listed under 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 VAC and below for supplying appliance, lighting and power loads from electrical distribution systems. Standard distribution voltages are 600, 480 and 240 VAC, standard load voltages are 480, 240, 208 and 120 VAC. The transformer is used to obtain the load voltage from the distribution voltage. Since no vaults are required for installation, these transformers can be located right at the load to provide the correct voltage for the application. This eliminates the need for long, costly, low voltage feeders.
