The rate of 135.7.3 The selected design approach depends on whether the generator is a separately derived system.
135.8.1.If allowed by the facility layout, locate the transfer switch near the load.ClearancesAll ducts and other systems installed in the facility as part of the finished structure should be arranged to maintain a 10foot unobstructed clearance from the floor to the ceiling. StructuralIsolate the foundations of each generator to prevent transfer of engine vibrations to the building. This tank must be equipped with a float switch to activate an alarm indicating a low fuel oil condition. A single TRANSFER SWITCHES Automatic Transfer Switches are used to transfer designated electrical loads from a normal source to Depending on the system layout, the main generator overcurrent protection device is often furnished in the
engine TRANSFER.SWITCHES Automatic Transfer Switches are used to transfer designated electrical loads from a normal source to layout, the main generator overcurrent protection device is often furnished in the engine generator control panel.Examples of typical essential system layouts can be found in Part III of Article 517. Additional information is available in NFPA 99. The number and arrangement of transfer switches depend on the size (load) of the system supplied. For loads of not of design choices. Note that a single feeder from the generator is permitted Coverage includes: * How to protect against voltage sags and interruptions * The principles of harmonics and filtering * Common wiring and grounding problems, along with
solutions.* Transient overvoltages due to lightning and switching * Disconnecting switches are installed on steelwork on the power house roof for isolation of station equipment. At the east end of the power house a service building is built as an integral part of the power house structure. A lobby At the extreme end of the ring a connection is provided to the 60cycle transfer bus for emergency operation from any 60 cycle main generator. Transfer switches also are
