It is a common mistake to use a metal ladder when changing a light bulb, for instance, or performing other household tasks near electrical wires. For these chores, use a wood or fiberglass ladder. When it comes to water, the simplest strategy is to ensure that you and your work area are dry. Dry intact skin, for example, has an average electrical resistance of 100,000 units of electrical resistance, or Ohms. If the skin is wet from perspiration, clothes, high humidity or other sources, the skin's resistance drops precipitously to 1,000 Ohms, which can change what would be an imperceptible or shocking experience with electricity into a deadly one.
Wet conditions are common during electrocutions involving standard household electricity.
The GFCI trips when only 6 milliAmps of current leak from the system. Unlike conventional household breakers, GFCIs are designed to protect human beings from electricity. GFCI outlets are placed in kitchens, bathrooms and around swimming pools. In some countries, the entire house or a subset of the circuits may be hooked up to a GFCI breaker located in the main electrical distribution panel. Before resetting a GFCI or any conventional breaker, first determine the reason it tripped.
