Can I replace a GFCI outlet myself?

For those who are handy with electrical work and possess a basic understanding of electrical safety, the question of whether one can replace a GFCI outlet oneself often arises. GFCI, or Ground Fault Circuit Interrupter, outlets are designed to prevent electrical shock by shutting off power when a ground fault is detected. While DIY enthusiasts may be tempted to tackle this task on their own, it's crucial to ask: is it SAFE and legal to do so? Proper installation and wiring of GFCI outlets is paramount for both personal safety and compliance with electrical regulations. So, the question begs: can a homeowner with the necessary skills and knowledge safely replace a GFCI outlet, or is it best to leave it to a professional electrician?
