What is the 3rd prong on a plug for?
The standard 3- prong receptacle is called a grounding receptacle because it allows a grounding wire to be connected from the electrical circuit to the appliance. However, some older plugs do not have an internally connected ground, and many people never actually connect the screw properly to a three-to-two prong adapter.
Electronic devices that connect using a voltage adapter that lowers the household current before it gets to the device do not have lethal voltage. Think laptop computers and game consoles that connect to a transformer brick or power adapter. Other devices may be shielded using plastic cases and other insulators to prevent short circuits from electrically charging their outer cases or shells.
However, water intrusion and other things can cause a potential for a lethal shock in a shielded device. All electrical appliances designed for outdoor and wet area use should have a third prong ground on the plug and be connected to a ground fault circuit interrupter GFCI receptacle.
If you have any questions about whether or not your electrical receptacles have proper grounding capability or if you need help in converting older two-prong receptacles to modern three-prong ones with grounds, please give Mr. Sparky a call today to schedule a service appointment.
