Electrical work in Sioux Falls

Electrical work in Sioux Falls is shaped by long, very cold winters, severe summer storms and state rules that let homeowners do some of their own wiring with a permit.

Homeowner wiring and permits

The South Dakota Electrical Commission lets homeowners wire the residence they own and live in without a license, but they must have an approved homeowner permit before starting any electrical work. If you're hiring an electrician, ask whether the job needs a state wiring permit and who will get it. The City of Sioux Falls also requires an Electrical Contractor's license for electrical work within city limits; ask the electrician for it.

Storm outages

During the May 12, 2022 derecho, straight-line winds of 50 to 70 mph were widespread across the region, with smaller areas of 80 to 100 mph and gusts measured at 97 mph in Madison and 107 mph in Tripp. Storms like that bring down lines and leave homes without power. A standby or portable generator must be connected through a transfer switch or interlock so it can't backfeed the utility lines. Ask the electrician which circuits you need during an outage, especially the furnace, sump pump and refrigerator, and how the generator will be sized. Portable generators must run outdoors, away from doors and windows.

Winter load

NOAA's engineering weather data for Sioux Falls gives a 99% winter design temperature of −11°F. Furnace blowers, heat tape, block heaters and space heaters all add winter load. Space heaters on old or shared circuits trip breakers and overheat outlets. Ask the electrician to check whether your panel and circuits can handle the loads you actually run.

Heat pumps

South Dakota is in the Department of Energy's North region, where new split-system central air conditioners must be rated at least 13.4 SEER2 and split-system heat pumps at least 14.3 SEER2 and 7.5 HSPF2. If you're adding a cold-climate heat pump or electric backup heat, ask whether your electrical service has capacity, and whether the circuit and breaker match the equipment's nameplate.

Surge protection

Lightning and storm-related surges damage electronics and appliance control boards. Ask about a whole-house surge protector at the panel.

Before you hire

Ask for a written estimate that lists the work circuit by circuit, the permit, and the inspection. Ask what brand of panel and breakers they'll install. For service upgrades, ask how they'll coordinate with your power company.
