Do NOT connect loads in excess of circuit breaker ratings.
6.1LOCATION AND SUPPORT
◆6.1.1 GENERATOR LOCATION
The most desirable location for the generator set is between the vehicle's main frame members. However, this is seldom possible. Most units must be installed on the side of the vehicle and are difficult to reinforce.
Many recreational vehicles have been factory equipped with an area for the generator set. Some vehicles may even have a generator compartment provided by the vehicle manufacturer.
Plan the generator location based on the following:
•The generator set must be installed on a framework that is part of the recreational vehicle, as outlined in Section 6.1.2.
•The location must provide an access opening that is large enough to permit generator removal (unless the generator is to be removed from underneath the sup- porting framework).
•The location must provide easy access to frequently serviced components, such as filters, oil drains, spark plugs and other common maintenance parts.
•The location must provide sufficient room to allow minimum clearances as outlined in Section 6.2. If sound insulation is to be used on the compartment
framework that has been made part of the vehicle frame structure by bolting or welding. The metal framework on which the generator will rest and which will restrain the generator set should consist of at least two horizon- tal beams. These beams should consist of (a)
The generator can be installed so that it sits on top of the horizontal support tubing if the vehicle design per- mits. Another method is to suspend the generator below the horizontal support tubing by means of suitable, structurally sound metal framework. The following gen- eral rules apply:
•Vehicle construction MUST be capable of supporting the weight of the generator.
•Whether the generator is mounted above the horizon- tal support tubing or suspended below the tubing, the supporting frame used must be structurally sound.
•If the generator cannot be bolted directly to the supporting frame or support tubing, consider
using additional tubing, angle brackets or other supports to give the supporting frame suffi- cient strength.

◆6.1.3 SUSPENDED MOUNTING
If you are going to suspend the generator below the hor- izontal support tubing, the suspension method you use with the vehicle frame members must (a) be able to sup- port the weight of the generator AND (b) provide suffi- cient restraint for the generator. One typical suspended mounting system is shown in Figure 6.2. The location of a suspended mounting system must be carefully planned, keeping the following general rules in mind:
