Rewiring a home can be a daunting task, but it doesn't have to be dangerous if you follow some simple precautions used by our grandparents' generation. As someone who has rewired parts of my home, I learned first-hand how knowledge passed down from previous generations can help get the job done safely.

In this article, I will share little-known rewiring tips used by our grandparents to help you update your home's electrical system without getting electrocuted.

Prepare Your Workspace Properly

Before starting any electrical work, you need to set up your workspace properly to avoid accidental shocks or electrocutions. Here are some tips our grandparents used:

Shut Off Power at the Breaker

The first step is always to shut off power to the circuit you'll be working on at the main breaker panel. Remember to double check with a voltage tester that the power is off. As my grandpa always said: "Test before you touch."

Cover the Floor

Lay down a non-conductive mat or cardboard to cover the floor where you'll be working. This prevents accidental contact between wires and the conductive floor. As my grandma warned: "Don't let your knees touch live wires."

Have Good Lighting

Make sure you have adequate overhead lighting in the workspace. It's easy to make mistakes working with small wires in dim lighting. A headlamp can be useful for hands-free illumination.

Tidy Up The Area

Remove any clutter and secure all tools/materials needed within arms reach. As my grandpa always said: "A tidy workspace keeps you safe." You don't want to be fumbling around near live wires.

Use The Right Tools

Our grandparents' generation relied on simple but effective tools for electrical work. These are some of their go-to rewiring tools:

Wire Strippers

Invest in a good pair of wire strippers. Self-adjusting strippers that firmly grip insulation make stripping less tiring. As my grandpa advised: "Let the tool do the hard work, not your hands."

Voltage Tester

Always have a non-contact voltage tester handy. Test wires before touching and double check that power is off. As my grandma always said: "Believe the tester, not your memory."

Insulated Screwdrivers

Only use screwdrivers with insulated handles. These prevent shocks from live wires. Regular screwdrivers can accidentally contact electricity.


A headlamp frees up both hands. Trying to hold a flashlight while working can lead to accidental contact with live wires.

Follow Safe Wiring Practices

How you handle wires during rewiring is critical for safety. Follow these tips used by past generations of electricians:

Keep Wires Untangled

Don't let wires wrap around arms or legs. As my grandpa taught: "Tangled wires grab you like a snake." Neatly position wires to avoid accidental contact.

No Looped Wires

Never wrap excess wire into a loop. Looped wires can overheat or induce harmful magnetic fields. Run excess wire neatly back to origin.

Use Insulated Connectors

Only make connections with insulated wire nuts or connectors. Exposed connections can arc and cause shocks or fires. Fully twist connectors until wires are secured.

Secure Wires

Use staples to securely fasten wires against studs. Loose or dangling wires can easily get tangled or damaged. Take time to staple neatly.

Double Check Circuits

Verify connections to the correct circuit before restoring power. As my grandpa would say: "Double check your work so you don't get surprised." Test that outlets and lights function properly when powered up.

Work Methodically and Carefully

Rushing electrical work often leads to mishaps. Follow the careful approach used by past generations:

Focus Intently

Give your full attention to the task at hand. As my grandma would say: "Focus fully or you'll get a shock, surely." Avoid distractions and don't work when overly tired.

Measure Twice, Install Once

Take precise measurements and make careful cuts. As my grandpa would advise: "Measure twice, only cut once." Mistakes lead to rework and wasted time.

Neat and Tidy

Work cleanly and keep everything organized as you go. As my grandma would say: "Neat work is safe work." Methodical working habits prevent errors.

Take Breaks

Take regular breaks to refresh your focus. Electrical work requires full attention. As my grandpa would say: "Step back when your mind starts to slack."

Ask For Help

If unsure, ask someone knowledgeable to assist. As my grandma would advise: "Two heads wire better than one." Get help before you risk mistakes.


Rewiring your home doesn't need to be a shockingly dangerous endeavor. By following the simple but effective safety tips used by past generations, you can upgrade old wiring safely and with confidence. The most important advice to remember is: focus intently, work neatly and methodically, use the proper tools, and don't rush the job. With prudent preparation and care, you can rewire your home just like our grandparents did - without getting electrocuted!
