The catch
WEN 8750-Watt Open Frame Inverter Generator
Gasoline is its only fuel.
Side by side
WEN GN875i vs Westinghouse iGen8200TFc: Westinghouse adds two more fuel options, and WEN suits gasoline-only plans
Quick verdict
Take the gasoline-only open frame, or the enclosed tri-fuel unit for its flexibility.
Before you buy
Why, and what it costs you
A running load of 6,200W on gasoline
Nominal margin is 800W for GN875i and 400W for iGen8200TFc. A negative number means the continuous rating has been exceeded.
Where this comes from
The measured total running load is assumed to be 6200W on gasoline. Margin = fuel-specific running watts minus 6200. Starting transients, altitude, temperature, power factor and per-leg limits are left out.
The catch
Westinghouse iGen8200TFc
Just because the outlet is 50A-shaped, do not assume the generator delivers 50A continuously at 240V.
WEN 8750-Watt Open Frame Inverter Generator
- Why pick it
- The GN875i’s 7000W gasoline rating and L14-30R are what you need
- You want gasoline as the sole factory fuel
- The catch
- Gasoline is its only fuel.
Westinghouse iGen8200TFc
- Why pick it
- Remote start plus propane or natural gas is a requirement
- Factory choices of gasoline, propane and natural gas are what you want
- The catch
- Just because the outlet is 50A-shaped, do not assume the generator delivers 50A continuously at 240V.

Which one fits
Pick the situations that sound like you
A continuous gasoline load of 6,200W
On gasoline the WEN delivers 7000W continuously and the Westinghouse 6600W. That 400W edge is modest, and gasoline is the one fuel the WEN supports.

Moving the generator and starting it when the power is out
The Westinghouse brings propane and natural gas, an enclosure and remote start. These are practical differences in outage fuel and ownership, though running output is lower on the gaseous fuels.

Hooking up the specified appliances or the home inlet
WEN’s product page states half-load runtime on its 4.2-gallon tank, while Westinghouse highlights quarter-load runtime. Headline hours therefore do not make an equal-load fuel economy comparison.

Running Westinghouse on natural gas costs 1320W
On natural gas, the iGen8200TFc drops from 6600W gasoline running output to 5280W. A 6200W plan therefore needs load shedding once the fuel is switched.

In practice
Differences you will notice
A running load of 6,200W on gasoline
Nominal margin is 800W for GN875i and 400W for iGen8200TFc. A negative number means the continuous rating has been exceeded.
How we worked this out
The measured total running load is assumed to be 6200W on gasoline. Margin = fuel-specific running watts minus 6200. Starting transients, altitude, temperature, power factor and per-leg limits are left out.
A total starting event of 8,000W
Measured against this separately specified total starting demand, GN875i has 750W of published peak margin and iGen8200TFc has 200W.
How we worked this out
Take the combined load during one motor start as 8000W, counting the appliances already running. Subtract 8000 from the gasoline starting rating. That shows nothing about surge duration or whether the motor starts successfully.
Running Westinghouse on natural gas costs 1320W
On natural gas, the iGen8200TFc drops from 6600W gasoline running output to 5280W. A 6200W plan therefore needs load shedding once the fuel is switched.
How we worked this out
6600 minus 5280 = 1320W, which is a 20% reduction. 6200 minus 5280 = 920W over the natural-gas rating. GN875i has no natural gas support.
Plug in your numbers
Can either generator run what you need?
This checks hard limits only. Personal preferences are left out of the math.
WEN 8750-Watt Open Frame Inverter Generator
Works with your numbersOn gasoline, it is rated for 7,000 running and 8,750 starting watts. With reserve, your load plan calls for 1,200 watts running and 2,900 watts starting.
Westinghouse iGen8200TFc
Works with your numbersOn gasoline, it is rated for 6,600 running and 8,200 starting watts. With reserve, your load plan calls for 1,200 watts running and 2,900 watts starting.
The estimate adds up the running watts of everything on at once, the biggest single startup surge and 15% headroom. Check each appliance label before you rely on it. Never run a fuel-burning generator indoors, in a garage or near doors, windows or vents.

Spec by spec
Where they really differ
| Spec | WEN 8750-Watt Open Frame Inverter Generator | Westinghouse iGen8200TFc | In practice |
|---|---|---|---|
| Running and starting output on gasoline | 7,000W running / 8,750W starting | 6,600W running / 8,200W starting | Each of continuous load and brief starting demand has its own limit. |
| Factory fuel choices | Gasoline only | Gasoline, propane and natural gas | Use the output rating for the fuel you have on hand. |
| Starting system | Electric with recoil backup | Remote and electric with recoil backup | How easy it is to start is a separate matter from how the generator is carried. |
| Handling layout | Wheeled open frame | 134.5lb wheeled enclosure | Look at the route out of storage and how it will get into a vehicle. |
| Connection panel | 120/240V L14-30R plus 120V TT-30R and household outlets | 120/240V 14-50R plus 120V TT-30R and duplex 5-20R | Match the exact receptacle, breaker and cord to the system you intend. |
| Gasoline tank | 4.2 gallons | 3.9 gallons | Runtime at your load cannot be worked out from tank size alone. |
| Power regulation | Inverter, Under 1.5% at full load | Inverter, Under 3% | Check waveform requirements specific to the load. |
Trade-offs
What each pick costs you
With WEN 8750-Watt Open Frame Inverter Generator
- Even though it produces clean power, the open frame is louder than an enclosed inverter.
With Westinghouse iGen8200TFc
- Propane and natural gas both rate lower than gasoline. Treat running load and motor starting demand as separate questions.
Change of plan
When the answer changes
The GN875i’s 7000W gasoline rating and L14-30R are what you need
Go with WEN 8750-Watt Open Frame Inverter Generator. On gasoline the WEN delivers 7000W continuously and the Westinghouse 6600W. That 400W edge is modest, and gasoline is the one fuel the WEN supports.
Remote start plus propane or natural gas is a requirement
Go with Westinghouse iGen8200TFc. The Westinghouse brings propane and natural gas, an enclosure and remote start. These are practical differences in outage fuel and ownership, though running output is lower on the gaseous fuels.
Decision guide
How to decide
Either take the gasoline-only open frame, or go enclosed for tri-fuel flexibility.
Let the fuel set the load list
On gasoline the WEN delivers 7000W continuously and the Westinghouse 6600W. That 400W edge is modest, and gasoline is the one fuel the WEN supports.
Ownership differences to weigh
The Westinghouse brings propane and natural gas, an enclosure and remote start. These are practical differences in outage fuel and ownership, though running output is lower on the gaseous fuels.
Connection and installation to confirm
WEN’s product page states half-load runtime on its 4.2-gallon tank, while Westinghouse highlights quarter-load runtime. Headline hours therefore do not make an equal-load fuel economy comparison.
What this page can’t tell you
- Everything is derived from specifications. Measured generator or motor-start tests played no part.
- Usable output is open to reduction by altitude, temperature, fuel supply and individual 120V leg limits.
- A CO shutoff does not make a garage, an indoor space or an enclosed shelter safe for a generator.
