The NEC guarantees safety by:1. Requiring that all electrical systems be grounded. This ensures that there is a low-impedance path for fault current to flow to ground, minimizing the risk of electric shock.
2. Mandating that all ground fault circuit interrupters (GFCIs) be installed in areas where there is a risk of electric shock, such as bathrooms, kitchens, and outdoor areas. GFCIs are designed to trip when there is a current imbalance between the hot and neutral conductors, which can occur when a person comes into contact with a live wire.3. Specifying that all electrical equipment be properly bonded to the grounding system. Bonding ensures that all metal parts of the electrical system are connected together, providing a continuous path for fault current to flow to ground. Flag for review
