3. Do not try to modify any part of the power cord by yourself-
You need to refrain from cutting the length of the cord or taking off any prongs as it may alter the safety feature of the device. Any modifications to the power cord may be quite dangerous. Also, most of the power cords are not suitable for outdoors. Being exposed to the elements can corrode their outer layer and may lead to electrocution. You should install power cords only as instructed.
4. You should use extension power cords only as a temporary option-
This is the most basic rule for using an extension cord. These only serve as a temporary solution. Extension power cords although convenient, may not be as safe as your typical power outlet. Also, due to the ease of use, there are more chances of them being misused. Therefore, it is crucial to connect your electronic device to a power outlet for a more permanent solution.
