Self-grounding electrical outlets are designed to protect you from electrical shock. Modern building codes require all outlets to be either self-grounded or ground-fault circuit interrupters. Electricity is always in search of the simplest path to reach earth. The use of improper electrical outlets can lead to shock or even electrocution.
