Electrical Tips Every Home Renovator in Nelson Should Know
How DIYers and Homeowners Can Avoid Common Wiring Mistakes
Nelson's home renovation scene is thriving—from fixing up quaint villas in The Wood to adding modern extensions in Stoke. But while people get excited about picking paint colors, floors, and layouts, they often forget something important: the wiring in their homes.
Whether you're an experienced DIYer or starting your first renovation, avoiding common wiring errors plays a crucial role in making sure your home works well, stays safe, and is ready for the future. As a reliable Nelson residential electrician, Mako Electrical has encountered the good, the bad, and the hazardous. Let's explore what you should know before you begin to open walls or drill holes.
The Importance of Avoiding Wiring Mistakes
Wiring errors during home updates can result in more than just failing inspections—they can start fires, cause electric shocks, and cost thousands to fix. Many do-it-yourself renovators in Nelson tackle electrical tasks without grasping the NZ Electrical Code, which controls what jobs require a certified electrician.
Some problems might not appear right away. They hide in walls or ceilings waiting for the next power spike, water drip, or overload to cause real harm. By knowing where home improvers often mess up, you can make smarter choices—and figure out when to ring the experts at Mako Electrical.
The Most Common Wiring Errors (And How to Steer Clear of Them)
1. Overloading Circuits Without Upgrading the Switchboard
People doing renovations often add new power points or lights without checking if their switchboard can handle the extra load. This can cause circuit breakers to trip often—or even worse, make wires overheat.
Tip: Always get a qualified electrician to check your switchboard before you add new circuits. Mako Electrical offers switchboard upgrades that suit modern needs.
2. Poor Cable Routing and Support
Putting wires through wall studs and ceiling spaces might seem easy, but bad routing can make cables rub, get too hot, or get damaged by nails or screws during future work.
Tip: Make sure you secure cables , shield them from sharp edges, and keep them away from insulation or plumbing. If you route them incorrectly, inspectors will flag it as a problem.
3. Wrong Wire Gauges
When you use wires that are too thin (wrong gauge) for lights, outlets, or appliances, you risk overheating. many DIY enthusiasts don't know how to calculate loads to pick the right wire.
Tip: Talk to a licensed electrician or use Mako Electrical's electrical design service to get your wiring right from the start.
4. Missing or Faulty Earth Connections
Earthing plays a crucial role in safety. It diverts extra current to the ground safeguarding people and devices. Many older homes in Nelson lack proper earthing or have outdated systems, which DIY renovators might overlook.
Tip: If your house hasn't undergone rewiring , include an earth continuity test in your renovation checklist.
5. Illegal DIY Work
New Zealand law requires a licensed electrician to perform many electrical tasks. This rule applies to installing new circuits, switchboards, and connecting to mains power. Doing this work yourself can result in fines, invalidate your insurance, or cause you to fail a Code Compliance Certificate.
Tip: Get to know what you can and can't do yourself. If you're unsure, Mako Electrical breaks it down .
Figuring Out When to DIY vs. When to Ring Mako Electrical
