Cautious running and starting watts from Champion's and DTE Energy's wattage charts. "Check": it runs once started, but the charts' start-up surge is more than its 11,400 starting watts, so read your appliance's label (amps × 120 = watts). Wired-in loads need a transfer switch fitted by a qualified electrician. Your own list: the generator calculator.
Questions
Can the Firman T09275 run a refrigerator?
Yes. A refrigerator needs up to about 750 running watts and 2,600 to start on the charts, within its 9,200 running and 11,400 starting watts.
Can the Firman T09275 run a well pump?
Yes. A 1/3 to 1/2 HP well pump needs up to about 1,000 running watts and 3,000 to start on the charts, within its 9,200 running and 11,400 starting watts. A well pump is wired in, so it needs a transfer switch fitted by a qualified electrician.
Can the Firman T09275 run central air?
No. DTE Energy's guide puts a 3-ton central air conditioner at 6,000 running watts and about 18,000 watts to start. That takes a standby generator.
