Can you plug an extension cord into another extension cord?
Besides, can you use 2 extension cords together?
While stringing together two extension cords can work as a temporary solution, such as in the case of a short power failure, it creates a significant risk when used as a long-term solution. Extended cords reduce the wattage capabilities of each cord and may lead to meltdown and fire.
In respect to this, why should you not plug one extension cord into another?
Using extension cords properly is critical to your safety. With continuous use over time, an extension cord can rapidly deteriorate, creating a potentially dangerous electric shock or fire hazard. Multiple plug outlets must be plugged directly into mounted electrical receptacles; they cannot be chained together.
Because this is hard-wired into the electrical system an extension cord may be plugged into it. This is the only time it is acceptable to plug an extension cord into a power strip. Extension cords are only for temporary use and are not to be left plugged into wall outlets when not being actively used.
