A Brief History of Electrical Wiring
The history of electrical wiring is fascinating, and full of strange twists and turns. Thomas Edison first began working on electrical lighting systems in the 1870s. His early lightbulbs and wiring systems were extremely primitive and potentially dangerous. The early electrical wires were uncovered, allowing for shorts and fires. But over time, Edison and other inventors began to refine electrical wiring, ultimately leading to the safe, insulated wires we have in homes today.
Some key innovations that improved electrical safety included:
-
Insulated wires - Early electrical wires had no insulation. This allowed electricity to arc across wires, causing fires. Insulated rubber and cloth coverings helped prevent this.
-
Fuse boxes - These boxes contained early fuses that would blow out if too much current went through a wire, preventing overloads.
-
Circuit breakers - A more advanced version of fuses, these automatically cut power if there are issues.
-
Grounded wires - A third "ground" wire prevents shocks by giving electricity a safe path to flow.
-
Plastic wiring - Replaced older cloth-insulated wires, less prone to fraying and damage.
So while early electrical work seems bizarre by today's standards, it paved the way for the safe, reliable systems we have now. Understanding this history gives insight into improving home wiring.
Common Electrical Wiring Issues in Homes
While home electrical systems are far safer today, wiring problems can still occur. Some common issues include:
-
Faulty circuits - Repeated tripping of breakers or blown fuses indicates an overloaded circuit. This needs to be inspected.
-
Exposed wires - If insulation frays or cracks, bare wires become exposed, risking fires and shocks.
-
Aluminum wiring - Used in some homes between 1965-1973. More prone to overheating and fire than copper.
-
Grounding problems - Faulty grounding puts you at risk of shocks. Any issues should be repaired.
-
Voltage drops - Wiring that's too thin or long can cause voltage to drop before reaching appliances. This can damage electronics or lights.
-
Rodent damage - Mice or rats can chew on wires, exposing them. Their waste can also corrode wires over time.
Being aware of these common problems points you in the direction of what to look for in your home's electrical system.
How Electrical Wiring History Helps Solve Wiring Problems
The innovations that improved electrical safety decades ago are key to solving wiring issues today:
-
Insulation - Ensuring wires have undamaged, sufficient insulation prevents arcs, shocks, and fires. Upgrading old wiring helps.
-
Overload protection - When breakers trip or fuses blow, it's usually because too many appliances are on one circuit. Adding circuits distributes power.
-
Grounding - Grounding issues can be fixed by ensuring wires are properly grounded to the breaker panel. Installing GFCI outlets also helps prevent shocks.
-
Sufficient gauge - When voltage drops, wiring may need to be replaced with thicker gauge wires capable of carrying more electricity.
-
Rodent control - Sealing up holes, using wire protectors, and keeping wires away from walls prevents rodent damage.
By going back to the early roots of electrical safety, and employing insulation, protection devices, grounding, and sufficient wires, you can update your home to use electrical wiring as safely as possible.
Final Tips on Solving Home Electrical Problems
Improving your home's aging wiring requires diligence and safety. Here are final tips:
-
Test wires - Use a multimeter to check for voltage drops that indicate insufficient wiring.
-
Inspect insulation - Visually check for any cracked or fraying wire insulation throughout the home.
-
Hire an electrician - Some wiring issues like grounding and circuit breakers require a licensed electrician.
-
Consider upgrades - If wiring is very old, upgrades like plastic sheathed wires may be better long-term.
-
Check connections - Loose electrical connections can cause drop outs or shorts.
-
Learn about your home's wiring history - Understanding what era wires are from provides insight into risks.
Home electrical systems can seem bizarre and complex. But the history of wiring innovations gives us a roadmap to identify and solve wiring problems - protecting your home and family from harm. Careful inspection, maintenance, and targeted upgrades will keep your unique home's power flowing safely.
