30 amp inlet
Can the Pulsar G12KBN run a house through a 30 amp inlet?
Runs
Yes, through a 30 A 120/240 V inlet and transfer switch or interlock. Its 120/240V 30A twist-lock outlet can feed both legs. Usable through the inlet: 7,200 W running (the 30 A inlet caps at 7,200 W). The essential-circuit list below needs about 4,440 W running and 6,790 W at the worst start, which fits.
Typical essential circuits
| Essential circuit | Running W | Starting W | Voltage |
|---|---|---|---|
| Refrigerator | 700 | 2,200 | 120V |
| Chest freezer | 700 | 2,200 | 120V |
| Furnace blower, 1/2 HP | 800 | 2,350 | 120V |
| Sump pump, 1/2 HP | 1,050 | 2,150 | 120V |
| Well pump, 1/2 HP | 1,000 | 2,100 | 240V |
| LED lights, 10 × 9 W | 90 | — | 120V |
| TV, router and phone charging | 100 | — | 120V |
| Total | 4,440 | + 2,350 largest start = 6,790 W peak |
Typical planning figures from a published generator wattage chart, not measured from a specific model. Check your appliance nameplates. A 30 A, 240 V inlet can carry at most 30 × 240 = 7,200 W.
Questions
Can the Pulsar G12KBN run a house through a 30 amp inlet?
Yes, through a 30 A 120/240 V inlet and transfer switch or interlock. Its 120/240V 30A twist-lock outlet can feed both legs.

What does a 30 amp inlet supply?
A 30 A, 120/240 V inlet (L14-30) can carry at most 7,200 W, split across two 120 V legs of 3,600 W each. It only powers the circuits your transfer switch or interlock connects.
Do I need an electrician?
Yes. A transfer switch or listed interlock and inlet box must be installed by a licensed electrician. Never backfeed through a wall outlet.
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.
