How bad do outages get around Wilmington?

Bad enough to plan for. Hurricane Florence made landfall near Wrightsville Beach on the morning of September 14, 2018, near the upper end of Category 1. The National Hurricane Center's report says about 1 million North Carolina customers lost power, including more than 90 percent in New Hanover County, about 97 percent in Pender County and more than 80 percent in Brunswick County. The NWS office in Wilmington recorded 23.02 inches of rain at the airport, the wettest event in the city's history, and notes the city was cut off for several days. Earlier, Hurricane Fran in 1996 brought an 86 mph gust to the airport and, by the Wilmington Star-News count the NWS cites, knocked out electricity for 1.5 million people. The highest gust on record at Wilmington is 135 mph, during Hurricane Helene in 1958.

When is the best time to install?

Before the season starts. NOAA's Atlantic hurricane season runs June 1 through November 30, with the peak around September 10 and most activity from mid-August to mid-October. Scheduling a site visit in the off-season leaves time for permits, gas utility work and inspections.

Who can install a standby generator in North Carolina?

The electrical side is licensed by the North Carolina State Board of Examiners of Electrical Contractors. The board lists a Limited license for single projects up to $60,000 on systems rated 600 volts or less, an Intermediate license for projects up to $150,000, an Unlimited license, and restricted classes including SP-SFD for residential dwellings. State law exempts owners doing electrical work on their own property for their own use, but not property that's being offered for rent, lease or sale. The gas line falls under the State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors, which issues a fuel piping license. You can look up both kinds of license on the boards' websites.

Do I need a permit, and from whom?

Yes. N.C.G.S. 160D-1110 requires permits before installing or extending electrical wiring, devices, appliances or equipment, and it bars a permit for work that requires a licensed contractor unless one will do it. Where you apply depends on where you live:

City of Wilmington and unincorporated New Hanover County: New Hanover County's permits and inspections office issues all building permits in the city, through its COAST portal.
Carolina Beach: the town says electrical, gas, mechanical and plumbing trade permits go through New Hanover County Building Safety.
Leland: the Town of Leland's Planning and Inspections Department handles permits within the town.
Hampstead and Pender County: Pender County Inspections and Permitting, in Burgaw, at the Hampstead Annex, or online through PORT.

How should a generator be placed on a coastal lot?

Follow the manufacturer's clearances from windows, doors and vents, and keep the unit out of low spots. In flood zones, FEMA's guidance on backup power fuel systems is to elevate equipment above the base flood elevation or design flood elevation, whichever is higher, and to anchor fuel tanks against flotation, since a partly empty tank can lift in floodwater. Ask your installer and the local floodplain administrator what elevation applies to your house.

What about portable generators?

The CDC says to run a generator outside and at least 20 feet from doors, windows and vents because of carbon monoxide. NC State Extension notes that a generator connected to house wiring needs a transfer switch so it doesn't back-feed into utility lines, and that a licensed electrician should install it.

Questions to ask an installer

What's your electrical license number, and who does the gas piping under which license?
Will you pull the permits and be there for the inspections?
What did your load calculation include, and does it cover the air conditioner's starting surge?
Where will the unit sit, and how does that meet clearance and flood elevation rules?
Do you service the brand you're recommending, and what's the warranty?

Common questions
