(i� � RFCFIV(�1 NOV 9 i981 <br /> � �AnE� <br /> Il/CONOO/OMLYG <br /> � To� JIM KULINSKI - SEATTLE CACD LACROSSE <br /> FnoM: STEVE ANDERSON ���I�� <br /> on <br /> onre: NOVEM6ER 5, 1981 ��.nC <br /> sue�Ecr: TRANE PTAC <br /> ��� <br /> Jim, it is common knowledge that the PTAC cord set is rated at <br /> 250 volts. However, b�acause we require a subbase for 265/277 volt <br /> applications, we .lo not violate U.L. requireinents. U.L. requires <br /> that when using 265/277 volts, the units are to be permanently <br /> wired. They also say that when a subbase is used, thus concealing <br /> the plug and receptacle, the units are, therefore, considered to be <br /> permanently wired. <br /> As far as tlie question of 2G5 volts versus 277 volts, we also meet <br /> the U.L. requirements. We rate our units at 265 volts instead �f <br /> 277 volts only because 265 volts is the utilization point for 277 volt <br /> wiring. Actually, we are approved to plus or minus 10% of the <br /> 265 volt rating point. In other �aords, our 265 volt PTAC equipment <br /> could operate at voltages up to 291.5 volts. <br /> Jim, I hope this helps you to convince your inspector that our units <br /> are acceptable for your particular job. If you or your local inspector <br /> have any questions, please feel free to call me or John Moore of U.L. <br /> , John's number is (312) 272-8800. <br /> / � <br /> .�d �V� � . <br /> STEVE ANDERSON, PRODUCT SPECIALIST <br /> PACKAGED PERIM[TER SYSTEht PRODUCTS <br /> /fn <br /> ;i', ;��•, <br /> �i�. <br /> .� � ;.�'°.r- <br /> � .. _-�..'�. <br /> --r'.F�' <br /> � J <br />
