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
  • Homeowners in need of an emergency backup power for their essentials
  • Professionals who want to ensure that a power failure will not prevent them from working

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 is powered by a 420 cc Briggs & Stratton OHV 4-stroke engine. It delivers 120/240V, runs on gasoline and offers a running wattage of 8,000W as well as a peak wattage of 10,000W.

This generator can be started thanks to a conventional pull-start mechanism, but also to a simple and elegant electric starter (battery included).

Thanks to a fuel capacity of 7.5 gallons, the 30742 can operate for around 9 hours at 50% load with a full tank (fuel consumption around 0.83 GPH).

Outlets

The control panel provides the upcoming 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

With its dimensions of L28.4 x W30.5 x H29.1 in, the conventional, open frame design of the Briggs & Stratton 30742 offers stability and allows the generator to be raised above ground level. The featured design is ideal for the outdoors and all tough environments.

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 allows for a quick, easy and convenient assessment of its gas level, as it is equipped with a built-in fuel gauge.

From a security standpoint, the product offers an automatic low oil shut-off and an overload protection (circuit breaker), 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

generator stats on infohub app

The InfoHub™ app gives you real time information

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.

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 therefore, can 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. If weight is your top priority, one of the champions in this power category is the Dewalt DXGNR8000, weighing just 183 pounds.
  • Regarding its autonomy, the autonomy of the 30742, reaching around 9 hours at a 50% load, can be considered as low end, compared to other products of a roughly equal output. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Champion 100416, as it provides around 12.5 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. This generator is somewhat less fuel efficient than devices of comparable output: its estimated fuel consumption reaches 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.
