A 274cc gasoline-only generator with remote start

The WGen5300c is Westinghouse's 6,600-watt peak, 5,300-watt running gasoline generator with a CO sensor. Amazon's model and part fields read WGen5300c, and the UPC matches the maker page; the selected listing option is gas only. It uses a 274cc OHV engine, a 4.7-gallon tank and automatic voltage regulation, with wheels to fit.

It runs on gasoline only, so there is no propane rating to plan around. The manual's carton list names a bottle of 10W-30 oil, a spark plug wrench, a wrench, a battery charger, an oil funnel, and mounting feet and wheels to fit. The product page adds a remote key fob. The manual says the wheels are only for moving it by hand, not for towing.

Running watts, runtime and power quality

Westinghouse rates it at 5,300 running watts on gasoline, with 6,600 peak for motor starts. The maker gives up to 14.5 hours at 25 percent load and 11 hours at 50 percent on a full tank. The manual says output falls about 3.5 percent per 1,000 feet of altitude and about 1 percent for each 10°F above 60°F, and that it is rated for continuous use up to 104°F.

Both the manual and the spec table list total harmonic distortion as 23 percent or less, and the manual lists a brushed alternator with AVR. That is the maker's own figure; if you plan to run sensitive electronics, compare it with the THD the device maker asks for. The noise figure is as low as 68 dBA, with no distance or load stated.

Outlets: L14-30R, TT-30R and a household duplex

The panel has one 120V 5-20R duplex, one 120/240V L14-30R twist-lock, and one 120V TT-30R RV outlet. The spec table says there are no GFCI outlets and lists the unit as ST Switch ready. The maker calls the TT-30R RV ready and the L14-30R transfer switch ready.

A 120/240V selector must be set to 240V to get 240 volts from the L14-30R, and the manual says the 120V-only outlets stop working in that position; switch it only with the engine off. The neutral is floating. The manual says a building connection needs a transfer switch installed by a licensed electrician, with the generator connected as a separately derived system under NFPA 70.

Starting, CO shutoff and the clearance rule

Starting is by push button, remote key fob or recoil, with an automatic choke per the spec table. After a CO shutoff, the manual says remote-start units must be restarted from the panel button. The CO sensor shuts the engine down when CO accumulates, flashes red for at least five minutes, flashes yellow for a fault that only an authorized service center can fix, and does not replace indoor CO alarms.

The manual requires at least five feet of clearance on all sides including overhead while running and in storage, a flat solid surface, and outdoor use far from windows, doors and vents. It says not to run it in a truck bed, camper, trailer or an RV's generator compartment, or next to walls or buildings. Weight is 136.6 pounds, and the manual says to get help lifting it.

The maker's own documents disagree on CARB and oil capacity

The product page's spec table says CARB compliant no, while the manual's specification list names EPA and CARB certifications. Amazon's bullet mentions EPA compliance only. We cannot tell from these documents which applies to a unit sold today, so California buyers should confirm with Westinghouse before ordering.

Oil capacity also differs: the spec table says 20.3 ounces and the manual says 0.74 quarts, or 0.7 liters. The engine ships without oil, and the manual says to add the included bottle gradually near the end because factory test oil may remain. Check the dipstick rather than pouring a fixed amount.

Break-in, maintenance and the warranty's labor limit

For break-in, the manual says not to exceed 2,650 watts, half the rated running watts, for the first five hours. Check oil before each use, change it after the first 25 hours or first month, then every 50 hours or six months, and monthly under heavy load or heat. The display shows P25, P50 and P100 reminder codes, and valve clearance is recommended for an authorized dealer.

Amazon's bullet describes three years of service, labor and parts coverage. Westinghouse's warranty document gives consumer buyers parts and labor for one year and replacement parts only for years two and three; the maker page lists one year for commercial use. The owner pays transport to a service provider, the starting battery and prime power use are excluded, and registration is recommended.
