A standby generator automatically provides backup power within seconds of a utility outage, keeping your lights, refrigerator, HVAC, and sump pump running. The installation includes pouring a concrete pad, setting the generator, running gas and electrical connections, installing an automatic transfer switch (ATS) at the main panel, and programming the weekly exercise cycle. NorCal homeowners increasingly rely on generators during PSPS (Public Safety Power Shutoff) events, which can last 24-72 hours during high fire-risk conditions. We install Generac, Kohler, and Briggs & Stratton units from 10kW to 26kW.

NEC Article 702 governs optional standby systems. The generator must be located at least 5 feet from operable windows, doors, and air intakes. An automatic transfer switch must prevent backfeed to the utility grid. Gas line work requires a separate plumbing permit.

Cronograma del Proyecto

Load Sizing & Site Selection

1-2 hrs

Calculate your home's essential load (or full load for whole-house coverage) to size the generator correctly. Select the outdoor location following minimum clearance requirements from windows, doors, and property lines.

Pad & Gas Line Installation

0.5-1 day

Pour or set the concrete pad, level it, and allow it to cure. Run the gas line from the meter to the generator location, install a shutoff valve and sediment trap, and pressure test the gas line.

Generator & Transfer Switch Installation

4-6 hrs

Set the generator on the pad, connect the gas supply, install the automatic transfer switch adjacent to the main panel, and run the power cable from the generator to the transfer switch.

Commissioning & Inspection

1-2 hrs

Start the generator, simulate a power outage to verify automatic transfer, test all circuits under load, program the weekly exercise schedule, and register the warranty. Schedule electrical and gas inspections.

Generator Installation en Hayward — Preguntas Frecuentes

How much does a standby generator cost in Sacramento?+

A 16-22kW standby generator fully installed in NorCal costs $8,000-$15,000 including the generator, transfer switch, gas line, concrete pad, and all labor. Larger liquid-cooled units (26kW+) for bigger homes can run $15,000-$22,000.

What size generator do I need?+

A 16kW generator powers most essential circuits (lights, fridge, HVAC, kitchen). A 22kW unit covers a typical 2,000-3,000 sq ft NorCal home entirely. We perform a load calculation to recommend the right size for your home.

Why do NorCal homeowners need generators?+

PG&E's PSPS events can shut off power for 1-3 days during high fire-risk periods, primarily affecting foothill and rural NorCal areas. Generators also protect against general outages during winter storms and summer heat waves that strain the grid.

How loud is a standby generator?+

Modern air-cooled generators run at 65-70 dB at 23 feet — about as loud as a normal conversation. Liquid-cooled models are even quieter. Most NorCal jurisdictions allow generators that meet the manufacturer's specified noise levels.
