A GFCI outlet, or ground fault circuit interrupter, is a type of outlet that provides protection against electrical shock. GFCI outlets are required in wet areas, such as bathrooms and kitchens, because they can help to prevent electrocution if a person comes into contact with water while using an electrical appliance.Standard outlets do not provide the same level of protection as GFCI outlets. If you are using an electrical appliance in a wet area, it is important to use a GFCI outlet to protect yourself from electrical shock.

There are two main types of electrical wiring: solid and stranded. Solid wire is made up of a single piece of metal, while stranded wire is made up of multiple strands of metal twisted together. Solid wire is typically used for low-voltage applications, such as residential wiring, while stranded wire is typically used for high-voltage applications, such as commercial and industrial wiring.
