Here are some tips to help ensure your safety when working on electrical projects. Never stand on wet or damp floors when working with electricity. Stand on a rubber mat and wear UL listed rubber gloves for added safety.
Make sure the width of insulated staples matches the width of the cable to be attached - accidentally stapling through a wire could result in an electrical fire or electrocution.
Never run more appliances from one receptacle than is recommended for that outlet. This will help reduce the possibility of blowing fuses.
Never use a penny or tin foil in a service panel instead of a fuse.
