Rewiring a home can be a daunting task, but with proper precautions it can be done safely without risk of electrocution. In the 1920s, before modern electrical safety standards, rewiring a home was particularly hazardous. However, by following some forgotten methods from that era, you can rewire your home the old-fashioned way without getting shocked.
Researching and Understanding 1920s Electrical Systems
Before beginning any rewiring project, it's crucial to understand the electrical system you're working with.
- Older homes often have knob and tube wiring which lacks grounding and has outdated insufficient amperages for modern electrical loads. Upgrading this wiring is recommended.
- 1920s wiring was typically cloth-insulated copper installed in a branched circuit design powering lighting, large appliances, and wall outlets separately.
- Common hazards included frayed insulation, overloaded circuits, inadequate connections, and lack of safety devices like fuses or breakers.
Consulting archives, historical building codes, and electrical engineering books from the 1920s can provide insight on safely updating these outdated systems.
Using Proper Safety Gear and Tools
Electricity is dangerous, so wearing protective gear can prevent electrocution and save your life:
- Rubber-soled shoes prevent shocks. Leather gloves also protect from arcs and sparks.
- Insulated tools like pliers and screwdrivers prevent conduction through metal. Use double-insulated power tools.
- Wear safety goggles and avoid wearing conductive jewelry when working with electricity.
Also ensure your electrical tools are properly grounded and fused. Having an emergency first aid kit on hand is wise as well.
Cutting Power at the Main Circuit Breaker
Before touching any wiring, turn off power at the main circuit breaker or fuse box.
- Verify power is off by testing outlets with a voltage tester or multimeter.
- For extra safety, also switch off individual branch circuit breakers.
- Put up caution tape and signs to warn others not to restore power during work.
Working on live wires greatly raises risk of electrocution. De-energizing the system is a mandatory first step.
Rewiring One Circuit at a Time
Take an incremental room-by-room approach when rewiring:
- Focus on one branch circuit at a time, leaving all others energized. This maintains power in the rest of the home.
- Label all wires to avoid confusion. Note connections before disconnecting old wires.
- Fish new wires through walls using proper conduit and secure boxes.
- Connect new circuit then test it thoroughly before moving to the next room.
Patience and care at each step is key. Rushing raises the chances of mistakes.
Hiring a Licensed Electrician
While rewiring a home yourself following these forgotten 1920s methods can save money, it is highly complex and potentially dangerous work.
- Considering hiring a licensed electrician for the project, especially if you lack electrical experience.
- They will know the modern safety codes and have the right tools and testing equipment.
- The cost for an electrician is often well worth avoiding the risk of electrocution or burning your home down.
If tackling it yourself, get permits, research thoroughly, go slow, and ask for help when unsure. By rigorously following the methods of the 1920s, you can rewire without getting shocked. But never forget that electricity always has the potential to kill.
