Questions
Can the Westinghouse WGen9500DF run BLACK+DECKER BDM05C 5,000 Btu/h window air conditioner?
Runs. Running draw 347 W fits within 9,500 running watts. Startup watts were not published; 12,500 starting watts is at least 3× the running draw, the common planning allowance for a compressor or pump start.
What watts were compared?
Generator: 9,500 running W and 12,500 starting W on gasoline. Appliance: 347 W running, startup not published.
How long will it run?
Fuel runtime depends on total load. Published runtime: 12 hr at 25% load on gasoline, 7 hr at 50% on propane.
Where did the numbers come from?
Westinghouse spec table: gas 12500 peak / 9500 running; propane 11200 / 8500; L14-30R and 14-50R; 6.6 gal; 12 hr at 25% gas, 7 hr at 50% propane; 74 dBA; 211 lb; THD under 23%. ENERGY STAR lists 5,000 Btu/h, CEER 14.4, 115 V, variable-speed compressor, and 260.4 kWh/year. Rated input is 5,000 ÷ 14.4 = 347.2 W. That matches the listed annual energy at the DOE room-AC assumption of 750 hours (347.2 × 750 ÷ 1,000 = 260.4). The 347.2 W figure is the draw while cooling at the rated condition, not a whole-year average. Startup watts are not published.
Safety first
- Run a generator outdoors only, at least 20 feet from the house, with the exhaust pointed away from doors, windows and vents. Never in a garage, basement, shed or crawlspace, even with the door open.
- Carbon monoxide is odorless and can kill in minutes. Keep battery CO alarms working inside the home.
- Never backfeed a house by plugging a generator into a wall outlet or dryer receptacle. It can energize utility lines and kill a lineworker or a neighbor.
- Connecting to home wiring requires a transfer switch or a listed breaker interlock with a power inlet box, installed by a licensed electrician and permitted where your jurisdiction requires it.
