GFCI stands for ground fault circuit interrupter, which means it has the ability to detect a ground fault and shut the circuit down before it creates hazards. General breakers may also do that because ground faults can cause overloads, but they’re more focused on amp overloads from any cause. GFCIs are often installed in specific outlets, but breakers can come with GFCI capabilities built in for broader ground fault protection.

Moving an electrical outlet typically costs between $25 and $300. The final price depends on several factors, including the type of outlet, the condition of your existing wiring, and the state of your walls. For example, working on exposed walls without drywall is easier and less expensive for an electrician. However, if the walls are finished, the cost may increase to account for necessary repairs afterward. It's recommended to consult a professional for a precise quote based on your specific situation.
