Ground fault circuit interrupters (GFCIs) are electrical outlets that shut off when it senses an overload or surge in electricity. The GFCI outlet instantly trips when experiencing a power surge, triggering the breaker to cut the electrical current to reduce the risk of electrocution. Most building codes require the use of a GFCI outlet when installed near a water or moisture source due to the increased risk of an appliance shorting.
To comply with most local building codes, in many instances, you need a building permit for home remodeling projects. Local building departments require a building permit to change load-bearing walls or install plumbing or wiring. Some building departments require permits for other types of updates as well.
