Step-by-Step Guide on How To Check House Electrical Wiring

So, you’ve decided to take the plunge and dive into the world of DIY electrical checks. Kudos! But before you start, remember the age-old saying: “It’s all fun and games until someone gets electrocuted.” Alright, maybe that’s not the exact saying, but you get the gist. Let’s ensure your DIY adventure is both safe and informative.

  1. Disconnecting power: Before you start, turn off the main breaker. It’s the equivalent of putting on your seatbelt before driving. According to the U.S. Consumer Product Safety Commission, nearly 400 electrocutions occur in the U.S. each year. Let’s not add to that statistic.
  2. Checking outlets: Grab your multimeter and test the voltage of your outlets. If it reads between 110-120 volts, you’re in the clear. Is anything outside this range? Time to call in the pros.
  3. Inspecting switches: Flick them on and off. They should operate smoothly without any sparks or delays. If it feels like you’re trying to light a campfire with wet wood, there’s a problem.
  4. Examining light fixtures: Notice any flickering or dimming? It’s not a sign from the universe; it’s a sign of potential wiring issues.
  5. Looking for visible damages: Keep an eye out for frayed wires or burn marks. These are red flags, signaling it’s time for some repair or replacement.
