Things to Consider When Buying an Extension Cord for a Microwave
When you want to buy an extension cord for your microwave, you must know some important things about it. With proper knowledge, you can pick the right extension cord that is safe and suitable for your microwave oven. Here I provide things to consider when buying an extension cord for a microwave as follows.
You must choose a 14-gauge or 12-gauge extension cord for a microwave because it is designed for large appliances. The 16-gauge and 18-gauge extension cords are thin and have low amps capacity, while a microwave uses more wattage and ampere. Therefore you must check the gauge and choose either a 12-gauge or 14-gauge cord for your microwave.
Power Capacity and Compatibility:
After gauge, the next important thing to check in an extension cord is its power capacity. A standard microwave extension cord comes with the maximum power capacity of 1875W, 15A and 125V. With such a high capacity, the cord is compatible for 700W to 1200W microwaves with below 15A usage.
You must check the power capacity of an extension cord before buying it. You must also check the power ratings of your microwave, it is given on its back. Make sure that the power capacity of the extension cord matches with your microwave power ratings.
The extension cord is available in various lengths from 1-foot to 100-feet. You should choose the cord length as required to make your microwave cord reach the power outlet.
I strongly recommend you to get an extension cord with less than 25-feet length. Because the current supply capacity of a cord reduces when it is too long which can cause voltage dropping problems. So, it is better and safer if you can manage with an extension cord for a microwave that is shorter than 25-feet.
A standard microwave comes with a 3-prong plug in which the third one is the grounding prong. You must check that the extension cord also has the same 3-prong male plug for the outlet and 3-prong female plug for the microwave plug. Only then it will be compatible to use with your microwave.
Do not use a 2-prong extension cord with your microwave because it will damage your microwave.
Flexible and Unbreakable:
The extension cord must be flexible enough to fold where required during installation. You must check that the cord is easy to fold and unbreakable so that it does not break if folded or stretched or twisted a little when installing in your kitchen.
In this way, you need to consider these five things to find a suitable extension cord for your microwave.
Can You Plug a Microwave into Any Outlet?
No, you cannot plug a microwave into any outlet. A standard microwave requires a 120V outlet with 15A or 20A (amp) ratings. So, you must check the volt and ampere of an outlet to know if it matches with the requirements of your microwave.
If the power outlet does not match with the requirements of a microwave, it is not safe to plug the microwave into that outlet. It can cause overheating, fire hazard and also damage the magnetron or other internal parts of the microwave.
