Portable Generator Home Backup Planner: Running vs Starting Watts Load Table, Motor Start Staging, Interlock Kit or Transfer Switch With an Inlet Box, No Backfeeding, Carbon Monoxide Placement, Fuel Math, and an Outage Runbook

Plan how a portable generator will actually run your house in an outage: list the loads you need with running and starting watts, stage motor starts so the generator does not trip, choose an interlock kit or transfer switch installed with an inlet box instead of backfeeding, place the generator away from the house for carbon monoxide safety, estimate fuel, and write a step by step runbook.

Act as a residential electrician and emergency preparedness planner who installs generator inlets and interlock kits, and has been called after storms to houses where someone ran a generator in the garage or backfed a dryer outlet. Inputs: - What must run in an outage, with nameplate or manual running and starting watts where known, and 120 or 240 volt: [Loads] - Home electrical: panel brand and size, well pump, sump pump, gas or electric heat, and other 240 volt loads: [HomeElectrical] - Generator owned or shortlisted: running and starting watts on each fuel, outlets (for example L14-30 or L5-30), tank size, and runtime from the manual: [Generator] - Outage history: how long, what season, how often: [OutageHistory] - Where the generator can sit: distance to doors, windows, and vents, cover from rain or snow: [Site] - Output format: [Format] Generate: 1. A load table from Loads: each load, volts, running watts, starting watts, and whether it is a motor. Mark any number not from a nameplate or manual as an estimate. 2. Sizing math: total running watts for the essential set, and the worst case surge when the largest motor starts while everything else runs, compared with the Generator rating on each fuel. 3. A staging plan: start the largest motor load first, add the rest one at a time, and name the loads that must never run together on this generator. 4. Connection method: an interlock kit on the main panel or a manual transfer switch, fed from a generator inlet box sized to the generator outlet, installed by a licensed electrician with a permit. Explain why plugging a generator into a house outlet (backfeeding) is illegal in most places and can kill utility line workers. 5. Neutral and grounding note: whether the generator neutral should be bonded or floating depends on the connection method; leave this decision to the electrician and the generator manual. Note that some gas furnace controls are sensitive to this. 6. Carbon monoxide rules from Site: run outdoors only, at least 20 feet from the house with exhaust pointed away from doors, windows, and vents, never in a garage even with the door open, and battery backed CO alarms on every level. 7. Fuel math from Generator and OutageHistory: runtime at your expected load, fuel per day, how much to store, stabilizer and rotation, and how the choice of gasoline or propane changes storage and output. 8. An outage runbook: steps in order from the moment power goes out to shutting down when power returns, written so another adult in the house can follow it. 9. A test schedule: monthly run under load and an annual dry run of the whole runbook. Constraints: - This is a plan to discuss with a licensed electrician, not wiring instructions. - Never invent appliance wattages without marking them estimates. No em dashes.
