It is generally not recommended to plug a microwave into an extension cord for several reasons:
Power requirements: Microwaves are high-power appliances that draw a significant amount of electricity when in use. Most microwaves require a dedicated circuit to handle their power demands. Plugging a microwave into an extension cord may overload the cord and the electrical circuit it's connected to, potentially causing overheating or tripping the circuit breaker.
Fire hazard: Extension cords are designed for temporary and low-power use. When used with high-power appliances like microwaves, they can become a fire hazard due to the increased risk of overheating and melting of the cord.
Voltage drop: Extension cords have a certain amount of resistance, which can lead to a voltage drop, especially over longer distances or with thinner cords. Reduced voltage can affect the microwave's performance and may even cause damage to the appliance.
If you must use an extension cord temporarily for a microwave or any other high-power appliance, it's crucial to choose an extension cord that is specifically designed for heavy-duty use and has a sufficient amp rating to handle the microwave's power requirements. Look for cords labeled as "14-gauge" or "12-gauge," as they can handle higher amperage loads.
However, it is best to avoid using extension cords with high-power appliances whenever possible. The safest and most reliable option is to have a dedicated outlet installed near the microwave's location to meet its power needs. If you don't have a suitable outlet nearby, consider consulting a qualified electrician to install one, ensuring the electrical setup is safe and compliant with local electrical codes.
