Recreational Vehicle Generator

•Conductors must be rated 221° F (105° C) or must be of a larger conductor size.

2.6.3 GENERATOR AC CONNECTIONS

Generator AC output leads (BLACK) “hot” and (WHITE) grounded neutral come out of the generator as shown in Figure 2.13. There is also a green lead that connects to ground in the junction box of the recreational vehicle.

HARNESS

•If using metallic conduit, vapor seal the end of the conduit where it enters the junction box. Do this because flexible metallic conduit is not vaporproof along its entire length.

2.6.5 ISOLATING DIFFERENT POWER SOURCES

Connections from the junction box must terminate in

adouble-pole, double-throw transfer switch (Figure 2.14). An alternate method for isolating different power sources is by using an isolating receptacle (Figure 2.15). Whichever method is used, be certain that both power sources are NOT connected at the same time.

2.6.6 POWER SUPPLY CORD

The power supply cord must comply with all appli- cable codes, standards and regulations. It must be large enough to handle the full amperage to which it will be subjected.

Leads BLACK to WHITE are protected against over- load by a 30-amp circuit breaker (CB1). Use this line-to-neutral connection separately to operate 120- volt, single-phase, 60 Hertz, AC loads requiring up to 3,400 watts (3.4 kW) of power.

Do NOT connect electrical loads in excess of any circuit breaker rating or probems will develop with circuit breaker tripping, which causes a loss of AC output. Also, do NOT exceed the gener- ator's rated wattage capacity. Add the watts or amperes of all lighting, appliance, tool and motor loads the generator will operate at one time. This total should be less than the unit's rated wattage/amperage capacity.

2.6.4 CONDUIT

Route the connections between the generator and the junction box through approved, flexible conduit. The following general rules apply:

2.6.7 GROUND FAULT CIRCUIT INTERRUPTERS

The National Electrical Code (NFPA 70, 551-7) requires that ground fault circuit interrupters (GFCIs) be installed on all external and some internal electri- cal receptacles. Contact the dealer for recommenda- tions.

2.7Battery Installation

2.7.1 RECOMMENDED BATTERY

Install a battery that meets the following requirements:

•The battery must be a 12-volt, automotive type storage battery.

•For prevailing ambient temperatures above 32° F (0° C), use a battery rated 70 amp-hours and capable of delivering 400 cold-cranking amperes.

•For prevailing ambient temperatures below 32° F (0° C), use a battery rated 95 amp-hours and capable of delivering 400 cold-cranking amperes.

NOTE:

If the battery is to be used to power other vehicle accessories, as well as start the generator, a bat- tery with a larger capacity may be needed.

•Cut wiring to the required length and allow extra wire for junction box connections.

•Carefully prepare conduit ends to prevent sharp edges from cutting through wiring insulation.

•Route conduit so it does not interfere with genera- tor movement.

2.7.2 BATTERY CABLES

Using battery cables that are too long or too small in diameter may cause a drop in voltage, which causes starting problems. For the best cold weather starting, the voltage drop between battery terminals and the generator connection point should not exceed 0.12 volts per 100 amperes of cranking current.
