When it comes to the safety of your home, not all wires are created equal, and choosing the right size is one of the most critical decisions you can make. Think of a wire as a pipe for electricity. Just as a tiny pipe can't handle a massive flow of water, a thin wire can't safely power a high-load appliance like an air conditioner or geyser. Using an undersized wire for a heavy-duty appliance can cause it to dangerously overheat, melting the insulation and creating a serious fire risk. Selecting the correct wire gauge for each specific application—from heavy appliances to simple lighting circuits—is the most important step in ensuring a safe, reliable, and efficient electrical system for your home.
