2.5.2 EXHAUST SYSTEM SAFETY
•Maintain a clearance of at least 3 inches (76 mm) between exhaust system parts and any combus- tible material (such as wood, felt, cotton, organic fibers or other like material). If the
•Extend the exhaust system at least 1 inch (25 mm) past the outer edge of the vehicle. Do not terminate the exhaust system under the vehicle.
•Terminate the exhaust tailpipe such that exhaust gases will not be drawn back into the generator compartment and recirculated.
•If there is any possibility of the tailpipe or muffler being damaged, protect these
•Install the generator exhaust system according to safe automotive practices.
•Use enough exhaust system hangers to prevent any part of the system from being dislocated.
•Use exhaust system parts recommended by the manufacturer. Using unapproved exhaust mufflers and exhaust system parts is the responsibility of the person(s) installing such unauthorized parts.
•Do not terminate the exhaust system under any opening, window or vent that can be opened or is not permanently sealed from the vehicle interior.
•Exhaust piping must be large enough to prevent excessive back pressure on the generator engine.
•Never tee the generator engine exhaust pipe into the vehicle engine exhaust piping. This causes excessive back pressure on the generator engine. Also, water from one engine can damage the other engine.
•Plan exhaust system installation carefully. Comply with all applicable codes, standards and regula- tions.
2.6Electrical Connections
Be sure to read Section 1.6.
The following general rules apply to electrical connec- tions in a recreational vehicle:
•Qualified electricians who are familiar with appli- cable codes, standards and regulations should install electrical wiring.
•The wiring should comply with codes, standards and regulations. The National Electrical Code (NFPA 70), and state and local codes apply.
•Switches and circuit breakers should be of a type approved for use in recreational vehicles and must be mounted and installed to prevent damage from road shock.
•Wiring must be of adequate size, have approved insulative qualities and be properly supported.
•Conduit and wire openings into the generator com- partment (if used) must be
2.6.1 ELECTRICAL JUNCTION BOX
Install an approved, square electrical junction box with a blank cover on the interior or exterior wall of the area planed for installation of the generator (NOT on the generator). Route the generator's AC output leads into this junction box through approved flex- ible conduit. This is the point of first termination for generator AC output leads.
2.6.2 WIRING
•Wiring should be of stranded copper to reduce the chance that vibration may cause breakage.
•Wire gauge size should be large enough to handle at least 115 percent of the installed generator's rated maximum current.
•Neutral conductors must be the same size as other leg wires.
•Route power supply conductors from generator AC output leads (white), (black) and the green ground wire through approved flexible conduit to the elec- trical junction box on the compartment wall.
If flexible metal conduit is used between the gen- erator and the compartment junction box, the con- duit end that terminates the compartment junction box must be
•From the junction box, route power supply wires through approved conduit to either (a)
