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.

•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
a
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
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:

2.7Battery Installation
2.7.1 RECOMMENDED BATTERY
Install a battery that meets the following requirements:
•The battery must be a
•For prevailing ambient temperatures above 32° F (0° C), use a battery rated 70
•For prevailing ambient temperatures below 32° F (0° C), use a battery rated 95
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.
