Homeowners unable to safely diagnose and repair unexpected electrical wiring configurations

DIY homeowners encounter non-standard electrical wiring (like single-pole switches with 4 wires instead of the expected 2-3) and lack the knowledge to safely diagnose the problem or determine if it's a code violation, a previous botched repair, or a legitimate configuration. Current solutions (generic online guides, electrician consultations) either don't address unusual cases or require expensive professional help for what might be a simple fix. This creates frustration, safety concerns, and decision paralysis about whether to attempt repairs or call an electrician.
