Those electrical outlets in our home are often taken for granted. They can play a important part in the safety of our homes structures. You need to do routine maintenance on your electrical outlets.
All you need is a small test light or portable lamp to tests the outlets. Plug the light in and make sure it turns on, this way you know you have a working outlet.
If you have any cracked covers you will want to replace them. Especially ones that are used most often.
You will also want to check for any frayed wires before plugging into your outlets.
Never overload your outlets, and when ever possible use power surge's.
