Most systems, unless they contain automated switch gear, have a means of disconnect between the generator and the load. This is typically a transfer switch or disconnect. Ensure the contacts on the switch are rated for the size of your system. 4.1. GENERAL ELECTRICAL SYSTEM When mounting electrical panels, a 3 foot clearance is required and the use of an emergency light to illuminate the unit during operation is typically required. Power for the emergency light should be from both the primary utility and the generator. This is highly recommend so that in the event of a malfunction there is a light source to see to work on the unit. Refer to your local building and electrical codes to ensure compliance. 4.2. CONDUCTOR SIZING CONNECTION This information is dependent upon your generator output and intended load. When connecting cables to the generator, make connections at the generator first. Make the connections at the load last. Failure to do so may constitute a fire or safety hazard. o All ampacities are typically calculated at 75 C (Celsius) (167 o F(Fahrenheit) in the conductor size charts. Building wire conductors should be rated at 90oC(194oF) to allow for different ambient temperatures that these conductors may pass through. All conductors are typically required by electrical code to be copper. The recommended conductor sizes are based on maximum current. Ampacities are found in NEC Article 310, Table 310-16. Conductor resistances are found in NEC Table 8 "Conductor Properties". 4.3. CONNECTING THE GENERATOR Please the refer to the electrical drawing of the unit and your transfer switch documentation for information related. Leave the installation only to a trained personnel and don’t forget to observe the local laws and permit requirements. Errors during the installation may damage the equipment and electrical devices connected to the unit and may create fire and electrocution risks. 5. EXHAUST SYSTEM 5.1. GENERAL (EXHAUST SYSTEM) Generator engines give off deadly carbon monoxide gas through their exhaust systems. Carbon monoxide gas, if breathed in sufficient concentrations, can cause unconsciousness or death. Exhaust gases must be piped safely away from any room or enclosure that houses a generator and to a well ventilated area where people will not be endangered. Besides the possibility of carbon monoxide poisoning, ex- Page 14 haust piping becomes extremely hot during operation and remains hot for a long time after shutdown. For that reason, the following precautions are necessary: • Avoid contact with hot engines, exhaust manifolds, exhaust piping and mufflers. Any of these can cause severe burns. • Where piping must pass through combustible walls or ceilings, special precautions must be taken to prevent fire or heat damage such as using heat thimbles through walls and ceilings. 5.2. GENERAL RULES FOR EXHAUST SYSTEM When installing an exhaust system for a generator, the following rules should be considered: • Exhaust piping should be of wrought iron or steel having adequate strength and durability. • Exhaust fittings may be of cast iron. A 9 inch spacing (10 inches (250mm) recommended) from the exhaust pipe and walls is also required by most local codes. • Low points in horizontal runs of piping should be provided with condensation traps, as well as condensation drains. • Piping and mufflers must be properly supported and connected. • A flexible length of exhaust pipe is required between the engine exhaust manifold and rigid exhaust piping. • Exhaust piping must be terminated safely outside a structure that houses a generator, in such a way that hot gases and sparks will be discharged harmlessly and will not blow against any combustible surface or material. • Exhaust piping must not terminate under loading platforms, structures, or near any opening in a building. • Where necessary, exhaust piping must be guarded and/or insulated to prevent burns. • Provide a clearance of at least 9 inches (229mm)(10 inches (250mm) recommended) between exhaust piping and any combustible material. • Keep exhaust piping well clear of fuel tanks, fuel lines, etc. 5.3. RAIN CAP A rain cap is recommended on the end of the exhaust pipe. The rain cap is attached to the end of the pipe and opens due to the pressure from the exhaust discharge force. The rain cap protects the exhaust system from the environment when the system is not running. 5.4. SPARK ARRESTOR Use of a spark arrestor is required by the U.S. Department of Forestry if located on lands under their jurisdiction. The spark arrestor is recommended in areas where combustible materials may ignite such as dry grass, leaves, or other combustible materials. AR-EXP-CUMMINS-07-00 OWNERS MANUAL Page 15 6. INSTALLATION CHECKLIST BATTERY INSTALLATION Battery is connected properly. Recommended battery is installed. Cables are clean and tight. Terminals are coated with anti-corrosion grease, and terminal covers are positioned. FUEL SYSTEM Complies with local and NFPA ...
