Description

Zoom on the Briggs & Stratton 30742

In a nutshell, the Briggs & Stratton 30742 is a portable generator mostly geared towards:

  • Food van owners who know that just a short power outage could lose them hundreds of dollars
  • Professionals who want to be able to deliver results, even during a power failure

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's design includes a gasoline-fueled 420 cc Briggs & Stratton OHV 4-stroke engine. With a 120/240V output, it gives a running wattage of 8000W and also a peak wattage of 10000W.

This generator features a simple traditional pull-start mechanism, but also a convenient and easy-to-use electric starter (battery included).

With a fuel capacity of 7.5 gallons, the 30742 may run for around 9 hours at 50% load with a full tank (fuel consumption around 0.83 GPH).

Outlets

The control panel features the following 5 AC outlets:

Two Duplexes 120V 20A (5-20R) GFCI
120/240V 30A (L14-30R) receptacle

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.

Portability

The Briggs & Stratton 30742 has a conventional, open frame design, of the following dimensions: L28.4 x W30.5 x H29.1 in, which offers support and allows it to be raised above ground level. The design is ideal for rough environments and demanding outdoor use.

Since the generator weighs 246 lbs, it will be incredibly difficult to manually lift it and transport it, even though it is technically considered to 'be portable' (in the sense that it is movable). However, its challenging mobility is solved by its wheel kit (⌀12") and its folding handle, which will ease its displacement, once it is on the floor.

Features

The generator includes a built-in fuel gauge, a quick, easy and convenient method of checking the device’s gas level.

As for its security measures, the device features an automatic low oil shut-off and an overload protection (circuit breaker), letting you 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

generator stats on infohub app

The InfoHub™ app gives you real time information

Briggs & Stratton’s InfoHub™ Portable Power technology (opens in a new tab) 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.

Emissions

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 and thus, may be used 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).

  • At a dry weight of 246 pounds, the Briggs & Stratton 30742 is one of the heavier devices which can produce between 7500 and 8500 running watts. In terms of weight, one of the champions in their power range is the Lifan LF8750iEPL, standing at just 185 lbs.
  • As far as autonomy is concerned, providing around 9 hours of runtime with a full tank at a 50% load, the 30742 falls into the low end in comparison with other devices of a comparable power output. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Firman H08053, as it provides around 12 hours.
  • Run times are important, yet thanks to their dependence on the fuel capacity, they should be judged along with the fuel consumption of the device. 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 wish to further improve in the area of fuel efficiency, the Pulsar PG10000B16, which boasts with a gas consumption of only 0.55 GPH, may be the right generator for you.

Price comparison

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.
