Zoom on the Firman H05752

In a nutshell, the Firman H05752 is a portable generator mostly geared towards:

  • RV travellers looking for even more independence
  • People occasionally participating in sporting competitions, open-air performances and outdoor festivals
  • 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 who want to be able to deliver results, even during a power failure

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 H05752 in use

The Firman H05752

With its dual-fuel technology, the powerful and versatile Firman H05752 provides an output of 120/240V. While gasoline-powered, it gives a running wattage of 5700W along with a peak wattage of 7125W. While propane-powered, it provides 5700 rated watts and 7125 starting watts.

With a noise rating of 74 dBA (just slightly more noisy than a shower), the generator features a simple traditional pull-start mechanism.

With a fuel capacity of 8 gallons, the H05752 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.

Since the H05752 has a somewhat high THD (<25%), it is advisable to not use it for the powering of sensitive electronic devices.

Outlets

The control panel features the following 6 AC outlets:

Two Duplexes 120V 20A (5-20R) GFCI
120V 30A (L5-30R) receptacle
120/240V 30A (L14-30R) receptacle

This Firman generator features an L5-30R receptacle, enabling an easy RV connection via an L5-30P to TT-30R adaptor. However, it is still not quite RV ready. Besides, as the H05752 holds a twist-lock L14-30R receptacle, it is transfer switch ready: you'll easily be able to connect it to your breaker box to power your home during 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 H05752 offers stability and allows the generator to be raised above ground level. The device has been designed for tough environments and demanding outdoor use.

While the generator is considered to be technically 'portable' (in the sense that you can move it), manually lifting and transporting it may be challenging, due to its high weight of 176.5 lbs. However, this lack of maneuverability is compensated by its wheel kit (⌀10") and its folding handle, with which you can conveniently shift it, once it's on the ground.

Features

Panel of the Firman H05752

The H05752's control panel

The H05752's control center features a convenient meter showing you voltage, frequency and lifetime hours to aid you with the monitoring of its status and activity.

In addition to this info, a light indicator allows you to instantly see if its oil levels are insufficient.

A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the generator.

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.

Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the Firman H05752 also is packed along with the following accessories: funnel, oil, propane hose and tool kit.

Emissions

The Firman H05752 is EPA-approved and CARB-compliant. It can therefore be sold and purchased in all 50 states, including California.

Moreover, it features a spark arrestor, which makes it suitable for use in forested areas.

The Firman H05752 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Firman H05752 compare to dual fuel generators of similar power (between 5500 and 6500 W).

  • Since the generator weighs in at a dry weight of 176.5 lbs, the Firman H05752 belongs in the expected weight range for dual fuel devices which can produce between 5500 and 6500 rated watts. In terms of weight, one of the champions in their power range is the Pulsar G65BN, standing at just 126 lbs.
  • Since this generator is rated for a lowest possible noise of 74 dBA, it can be considered as one of the more quiet of the products generating similar power. If noise emissions are important to you, one of the least noisy generators of this power range is the DuroMax XP7500DX with only 70 dBA.
  • Since the H05752 boasts with a run time of around 12 hours at 50% load, it can be safely judged as a device of a higher run time than most dual fuel generators of a comparable output. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Pulsar PG7750B, as it provides around 13 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 not fuel efficient compared to devices of similar output: its estimated fuel consumption stands at 0.67 GPH at a 50% load. If fuel consumption is your top priority, we suggest to check out the Pulsar G65BN, which has a fuel consumption of only 0.45 GPH and thus, is one of the most efficient devices in our database.

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.
