As winter sets in and heaters and electric blankets come out, it’s easy to overload power boards without even realising it. But that convenience can come with a serious risk—like overheating, damaged cords, or even house fires. The good news? Staying safe is simple with a few smart habits.
Here’s what every Kiwi household needs to know to stay safe this winter.
⚡ What Is a Multi-Plug Board?
Multi-plug boards (also known as power strips) let you plug multiple devices into one wall outlet. Handy? Absolutely. But in New Zealand, most are rated for a maximum 10 amps (about 2300 watts) – a limit you can hit fast with heating appliances.
🔥 What Can Go Wrong?
Overheating: Overloaded boards can get dangerously hot.
Electrical fires: Damaged or overloaded cords may spark or short.
Hidden danger: Multi-plugs hidden under furniture or rugs can overheat out of sight.
6 Tips for Using Multi-Plug Boards Safely
1. Plug heaters and blankets directly into the wall
Appliances like space heaters and electric blankets draw high current. Always plug them into a wall outlet – never a power board or extension cord.
2. Use multi-plugs for low-power items only
Stick to charging phones, powering lamps, laptops or TVs. Avoid plugging in high-draw items like toasters, kettles, or dryers.
3. Know your load limit
Standard NZ power boards are rated to 10 amps. Add up your appliance wattage and avoid exceeding the board’s total capacity.
4. Never daisy-chain boards
That means: don’t plug one power board into another. It multiplies the risk and can overload your circuit.
5. Keep them cool and uncovered
Avoid placing boards under rugs or couches. Trapped heat increases fire risk – and you may not spot warning signs like discoloration or a burning smell.
6. Check cords and plugs regularly
If it’s warm to touch, discoloured, or smells burnt – stop using it. Replace any worn or damaged boards or leads.
Bonus Tip: Consider Extra Wall Outlets 🔌
If your home relies on multi-plugs in multiple rooms, you might be better off getting a few extra wall sockets installed by a registered electrician. It’s a safer, more reliable option long-term, and it keeps things tidy too.
Winter Is the Season to Stay Safe & Warm
This is the time of year when overloaded plugs are most common. By following these easy safety tips, you can enjoy your heating, blankets, and gadgets without the fire risk.
