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.

The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, the extra features it benefits from, and any relevant emission compliance details.

Power & Run Time

The Firman H08053 in use

The Firman H08053

With its dual-fuel technology, the powerful and versatile Firman H08053 provides an output of 120/240V. While gasoline-powered, it gives a running wattage of 8000W along with a peak wattage of 10000W. While propane-powered, it provides 7250 rated watts and 9050 starting watts.

The generator is rated for a noise of 74 dBA (just slightly more noisy than a vacuum cleaner). Its starting mechanisms include a conventional pull-start mechanism and a convenient and easy-to-use electric starter (battery included).

Regarding its running time, the H08053, with a 8 gallons fuel capacity can operate for around 12 hours at 50% load with a full tank of gasoline (fuel consumption around 0.67 GPH). When using propane, it can run for around 5 hours (estimation based on a 20 lbs tank - propane consumption around 0.94 GPH).

The quite high THD (<25%) of the H08053 makes it unsuitable for powering sensitive electronic devices.

Outlets

The control panel features the upcoming 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

While this Firman generator is not RV Ready, its L5-30R receptacle can be used for a simple RV connection with an L5-30P to TT-30R adaptor. Besides, because the H08053 is equipped with a twist-lock L14-30R receptacle, it is transfer switch ready: it can power your home during a power outage, as it can be easily connected to your breaker box to power your household.

Portability

The Firman H08053 has the following dimensions: L30.2 x W27.5 x H26.3 in. In combination with its conventional, open frame design, they provide support and allow the generator to be raised above ground level. The generator is designed for ideal use outdoors and in rough environments.

Since the generator weighs 212 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). Still, once it is on the ground, its wheel kit (⌀10") and its folding handle can easily solve the issue of low mobility and allow for easy relocation of the device.

Features

The H08053's control panel

The control panel of the H08053 includes a convenient meter showing you voltage, frequency and lifetime hours, helpful for the monitoring of its status and activity.

In addition to this info, a light indicator allows you to instantly see if the oil level is too low.

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

As for its security measures, the device features an overload protection (circuit breaker) and an automatic low oil shut-off, letting you use it with a peace of mind.

Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the Firman H08053 also is packed along with the following accessories: funnel, oil, tool kit and propane hose.

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).

  • With a dry weight of 212 pounds, the Firman H08053 finds itself in the expected weight range for generators able to produce between 7500 and 8500 rated watts. If you are concerned by weight, one of the champions in the above-mentioned power range is the Dewalt DXGNR8000, with a dry weight of just 183 pounds.
  • As this generator can emit noise as low as 74 dBA, it finds itself in the average expected noise for this kind of power. For those who are looking for a less noisy device, we suggest the Predator 9500. With just 67 dBA, it is one of the most quiet devices in this power range.
  • As the H08053 features an autonomy of around 12 hours at 50% load, it has a higher run time than an average generator of its power range. If you consider autonomy on a single full tank as one of the deciding factors, one of the generators in the same power range that offers the highest run time is the Champion 100416, with 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. At an estimated fuel consumption of 0.67 GPH (gallon per hour) at 50% load, this generator is a rather fuel efficient one within its wattage category. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Pulsar PG10000B16. With a fuel consumption of as little as 0.55 GPH, it is one of the most efficient generators currently on the market.
According to our stats, the following comparison is pretty popular: Firman H08053 vs Firman P08004.

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.
