Zoom on the Briggs & Stratton 30742
In a nutshell, the Briggs & Stratton 30742 is a portable generator mostly geared towards:
- Food truck owners who want to ensure that their business is fully self-contained and does not rely on potentially unreliable external power
- Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
- Professionals in need of safely powering high-intensity work or lighting equipment
In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed, including its emission compliance information.
Power & Run Time
The Briggs & Stratton 30742 houses a 420 cc Briggs & Stratton OHV 4-stroke engine, which provides 120/240V, consumes gasoline and delivers a running wattage of 8000W along with a peak wattage of 10000W.
This generator can be started via a conventional pull-start mechanism, or a simple and elegant electric starter (battery included).
The 30742 can operate for around 9 hours at 50% load with a full tank (fuel consumption around 0.83 GPH), due to its fuel capacity of 7.5 gallons.
The control panel includes the following 5 AC outlets:
As it features a twist-lock L14-30R receptacle, the 30742 is transfer switch ready: in case of a power outage, you will be easily able to connect it to a breaker box and power your household.
The design of the Briggs & Stratton 30742 is a typical, open frame, with the dimensions of L28.4 x W30.5 x H29.1 in, offering support and stability and enabling the possibility of raising it above ground level. This type of design is ideal for tough environments and heavy outdoor use.
Although this generator is technically considered 'portable' (in the sense that it can be moved), its 246 lbs make it incredibly difficult to manually lift and transport. Nevertheless, it can still be moved quite conveniently with the help of its wheel kit (⌀12") and its folding handle, once it is placed on the ground.
The fuel level of the generator can be determined quickly, easily, and conveniently with the help of its built-in fuel gauge.
From a security standpoint, the product offers an overload protection (circuit breaker) and an automatic low oil shut-off, allowing you to use it with a peace of mind.
The 30742 also benefits from Briggs & Stratton’s CO Guard™ (opens in a new tab) carbon monoxide shutdown. This new patent-pending technology uses advanced algorithms to shut down the generator when harmful levels of carbon monoxide accumulate in the generator's operating area. It’s a welcomed additional security feature, but don’t forget to always take your generator outside (opens in a new tab).
Besides the usual set of documentation and owner's manual (opens in a new tab) to get you promptly started, Briggs & Stratton also included some oil in the 30742's packaging.
InfoHub™ Portable Power
Briggs & Stratton’s InfoHub™ Portable Power technology allows you to monitor your unit’s vital information such as power usage, run time and fuel level in real time, and directly from your computer or smartphone (via the InfoHub app for iOS or Android).
Besides its monitoring features, InfoHub can also keep you informed about your 30742 status and maintenance needs by sending you scheduled service reminders. It also lets you customize the way your generator communicates with you and can send notifications to your local certified dealer.
The Briggs & Stratton 30742 is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.
However, it features a spark arrestor, so it is adequate for use in forested areas.
The Briggs & Stratton 30742 versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Briggs & Stratton 30742 compare to generators of similar power (between 7500 and 8500 W).
- Considering its dry weight of 246 pounds, the Briggs & Stratton 30742 is one of the heavier generators producing between 7500 and 8500 running watts. Regarding dry weight, one of the champions in the same power range is the Dewalt DXGNR8000, with a dry weight of only 183 lbs.
- The 30742's autonomy is somewhat low end compared to devices of its power range, as it reaches only around 9 hours at 50% load on a full tank. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Champion 100416, which is able to run for around 12.5 hours.
- The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about fuel consumption as well. Compared to its peers, this generator is not exactly fuel efficient, compared to similarly powerful devices, with an estimated fuel consumption of 0.83 GPH at a 50% load. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.55 GPH, the Westinghouse WPro8500 is a device you should look out for.
As you can see from this interactive chart, when compared to other 7500-8500W generators, the Briggs & Stratton 30742 is on the average side of the price range.
Therefore, this generator nicely fits in the expected budget for this kind of product.
