Zoom on the Firman H08053

In summary, the Firman H08053 is a portable generator especially useful for food truck owners who want to ensure that their business is fully self-contained and does not rely on potentially unreliable external power.

In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device, along with its emission compliance information.

Power & Run Time

The Firman H08053 in use

The Firman H08053

The dual-fuel technology of the Firman H08053 allows for an output of 120/240V and provides superb power and versatility. If gasoline-powered, the device provides a running wattage of 8000W and a starting wattage of 10000W. If propane-powered, it gives 7250 rated watts and 9050 starting watts.

At a noise rating of 74 dBA (just slightly more noisy than a vacuum cleaner), this generator can be started via a simple traditional pull-start mechanism, or a convenient and easy-to-use electric starter (battery included).

With a fuel capacity of 8 gallons, the H08053 can operate for around 12 hours at 50% load using gasoline (fuel consumption around 0.67 GPH), or for around 5 hours (estimation based on a 20 lbs tank - propane consumption around 0.94 GPH) using propane.

As the H08053 has a relatively high THD (<25%), it is not recommended to use it to power sensitive electronic devices.

Outlets

The control panel features the following 5 AC outlets:

Duplex 120V 20A (5-20R)
120V 30A (L5-30R) receptacle
120/240V 30A (L14-30R) receptacle
120/240V 50A (14-50R) receptacle

Even if this Firman generator isn't quite RV Ready, it still allows for an easy RV connection via an L5-30P to TT-30R adaptor, thanks to its L5-30R receptacle. Besides, since the H08053 bears a twist-lock L14-30R receptacle, it is transfer switch ready: it is easily connectible to a breaker box and can power your home in case of a power outage.

Portability

With its dimensions of L30.2 x W27.5 x H26.3 in, the conventional, open frame design of the Firman H08053 offers stability and allows the generator to be raised above ground level. The device has been designed for tough environments and demanding outdoor use.

As the generator's weight is 212 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). Nevertheless, thanks to its wheel kit (⌀10") and its folding handle (a decent solution to its lack of maneuverability), the generator can be easily moved, once placed the ground.

Features

The H08053's control panel

The H08053 and its control panel include a convenient meter, which displays voltage, frequency and lifetime hours. This feature comes handy when monitoring its status and activity.

In addition to this info, the device’s light indicator will display if the oil level is too low.

Thanks to a built-in fuel gauge, the generator allows you to quickly, conveniently and easily check the gas level at a glance.

Security-wise, this product benefits from an automatic low oil shut-off and an overload protection (circuit breaker), which gives you a complete peace of mind when using it.

With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the Firman H08053 also comes with several accessories, including: propane hose, oil, tool kit and funnel.

Emissions

The Firman H08053 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 Firman H08053 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Firman H08053 compare to generators of similar power (between 7500 and 8500 W).

  • At a weight of 212 pounds, the Firman H08053 places in the expected weight range of the generators in the 7500-8500 rated wattage range. In terms of weight, one of the champions in their power range is the Dewalt DXGNR8000, standing at just 183 lbs.
  • Since the generator's noise is rated at 74 dBA, it has the roughly average expected noise for a device of similar power. If you’d prefer a less noisy device, one of the most quiet devices, which share the same power range with this one, is the Predator 9500, whose lowest noise levels reach just 67 dBA.
  • Thanks to an impressive running time of around 12 hours at 50% load, the H08053 benefits from one of the highest run times among generators of a similar output
  • 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. This generator is one of the more fuel efficient models of the aforementioned output range, as its estimated fuel consumption reaches just 0.67 GPH (gallon per hour) at 50% load. If you wish to acquire one of the most gasoline efficient products of this power range, the Pulsar PG10000B16, with a fuel consumption of 0.55 GPH could be in your good books.

Unlike many websites, we did our best to research each of the specs above. That being said, we are not immune to making the occasional mistake or omission. Should you notice any missing or incorrect values, don't hesitate to suggest improvements so we can address the issue.
* Propane runtime is our own estimation, based on a 20 lbs tank and NIST 1994 GGE (Gasoline Gallon Equivalent) formula: 5.66 lbs of propane = 1 gal of gasoline.

Can this unit be used to run furnaces that are power sensitive with circuit boards? (Asked May 21, 2020)

Probably not. The unit has a THD <23%. You'd have to check with your furnace manufacturer if that power is clean enough for these furnaces.

Can the neutral be unbounded from the frame? (Asked March 18, 2021)

No reason why this would not be impossible. You may refer to our article on neutral conversion.
