Using an extension cord for home appliances like a fridge or microwave is generally not recommended. Extension cords are designed for temporary use and for low-power devices such as lamps, chargers, or small electronic devices. Appliances like refrigerators and microwaves draw higher currents and require a stable and direct power source.
There are a few reasons why using an extension cord for such appliances is discouraged:
Overheating and Fire Hazard: Extension cords may not be capable of handling the high current required by appliances like refrigerators and microwaves. The prolonged high load can lead to overheating of the extension cord and may cause a fire hazard.
Voltage Drop: Longer extension cords or ones with a lower gauge (thicker wire) can experience voltage drop over the length of the cord. This can result in reduced power reaching the appliance, causing performance issues and potentially damaging the equipment.
Safety Concerns: Extension cords can easily get damaged or tangled, leading to exposed wires and potential electric shock hazards.
Code Violations: In many regions, using extension cords for fixed appliances like refrigerators and microwaves may be against building codes and regulations.
Instead of relying on extension cords, it's best to have a certified electrician install additional outlets or relocate existing ones to accommodate the appliances properly. This ensures that your appliances have a stable and safe power supply without compromising on safety. If you find that your current outlets are not sufficient, investing in a professional electrical upgrade is a safer and more reliable solution in the long run.
