Flickering often points to a loose connection, either at an outlet, within your panel, or at the service entrance. Given our area's high surge risk from frequent lightning, these voltage fluctuations can also damage sensitive electronics. While Black Hills Energy manages the grid to the meter, issues inside your home are the homeowner's responsibility. Installing whole-house surge protection at the panel is a critical defense, but diagnosing the flicker's source is the first step to a stable, safe electrical system.

A 100-amp panel from 1972 is likely at or beyond its safe capacity for those additions. More critically, many panels from that era in Custer are the recalled and hazardous Federal Pacific brand, which must be replaced before any new load is considered. A Level 2 EV charger alone can require a 40-50 amp dedicated circuit. We must first perform a full load calculation and almost certainly upgrade to a new 200-amp service with modern, safe breakers to support these major appliances.

For an emergency like a burning smell, which indicates an active fire hazard, we dispatch immediately. From our starting point near the Custer State Park Visitor Center, we can typically reach most Downtown Custer addresses via US-16 within 5 to 10 minutes. Your first action should be to turn off the main breaker if it's safe to do so and call 911 if you see smoke or flames. Our priority is securing the scene to prevent an electrical fire.

Absolutely. Rocky, resistive soil common in the pine forest hillsides around Custer State Park can make achieving a low-resistance ground extremely difficult. A proper grounding electrode system is essential for safety and surge protection. Furthermore, heavy tree canopy can cause line interference during high winds. We often need to use specialized grounding methods or longer ground rods to reach conductive soil, ensuring your system meets code and protects your home from lightning strikes.

Overhead service masts, while common here, are exposed to the elements. In winter, ice accumulation can add dangerous weight and stress. Year-round, check for any sagging or damage to the mast, the service drop cable, and the weatherhead where it enters your house. Ensure tree branches are trimmed well back from the lines. Any work on the mast or service entrance conductors must be performed by a licensed electrician, as it involves the live utility connection before your meter.

Homes in Downtown Custer built around 1972 often have original NM-B (Romex) wiring, which is now over 50 years old. This aging system was never designed for the simultaneous loads of modern kitchens, home offices, and entertainment centers. Insulation can become brittle over decades, and the 100-amp service common for that era is now considered minimal. Upgrading your electrical infrastructure addresses both safety and capacity for today's standard of living.

In South Dakota, all major electrical work requires a permit from the South Dakota Department of Labor and Regulation - Electrical Commission and must be performed by a contractor licensed by the South Dakota Electrical Commission. We adhere to the 2023 NEC, which mandates AFCI protection for most living areas and specific guidelines for service upgrades. As your electrician, we handle the permit filing, inspections, and all compliance paperwork, ensuring your installation is legal, insurable, and safe.

Winter peaks strain the entire grid and your home's wiring. Ensure your heating system is serviced and on its own dedicated circuit. For ice storms that cause prolonged outages, a properly installed and permitted generator with a transfer switch is a safe solution—never use a portable generator indoors or backfeed your panel. Given our low temperatures, consider the age of your exterior service mast and wiring for brittleness. Proactive maintenance now prevents emergency calls during a storm.
