Answers to Common Questions
View All FAQsHow often should electrical panels be inspected for safety?
Electrical panels should be inspected once a year by a licensed electrician, and anytime you’re buying a home. Most homeowners bundle this with a full-system electrical safety inspection to catch small issues early and keep breakers, wiring, and connections working safely. We perform these checks throughout the Dane area and provide clear next steps if we find anything that needs attention. Cardinal Care Club members can request one complimentary electrical inspection as part of their membership. A realistic technician insight: taking time to label each circuit during the visit makes future troubleshooting faster and safer.
If you ever notice a burning odor or visible scorch marks at the panel, turn off power to that circuit and call an electrician immediately. <br/> Updated: 2026-05-05 <br/> Need help in Dane, WI? Call (608) 291-6473 or book online.

Electrical wiring should be professionally checked at least once a year, and any time before you buy a home. The most common drivers are age-related wear, loose connections, and overloaded circuits that build up over time. A proper check reviews wiring, breakers, panels, conduits, boxes, and appliance connections. Our team performs these inspections for homeowners in the Mcfarland area. Cardinal Care Club members can request one complimentary electrical inspection.
Schedule sooner if you notice:
- Frequent breaker trips or outlets that feel warm
- Flickering lights or intermittent power at one circuit
- Burning smells, buzzing at a panel, or discoloration on devices
- Recent storm damage, DIY wiring, or older aluminum branch circuits
If you notice a burning odor or visible arcing, switch off the affected breaker and call a licensed electrician. <br/> Updated: 2026-04-01 <br/> Need help in Mcfarland, WI?
