How to add GFCI protection to a circuit?
The simplest way to add GFCI protection to your system is to replace the first receptacle (the one closest to the panel) in each circuit with a GFCI receptacle. If you do that, and connect the panel feed wires to the LINE terminals and the wires feeding the rest of the receptacles or lights to the LOAD terminals. then you can replace all of the other receptacles on that circuit with 3-slot grounding receptacles.

To add grounding to an existing panel, drive a ground rod into the ground and connect a grounding wire to the main electrical panel.
Why does my circuit breaker trip?
Without a grounding wire, the circuit breakers on your electrical panel board may not work properly. Circuit breakers will trip if there’s a fault in the system. For example, if a wire were to come loose and touch a metal enclosure, like a mixer or toaster, that metal enclosure would become live. Because the wire touches the metal enclosure, the circuit would not be broken and the circuit breaker would not trip to cut power to the circuit.
What happens when a circuit breaker breaks?
When one of these wires is damaged or an appliance breaks, the ground ensures that the circuit breaker in the electrical panel will trip, cutting power to the circuit and preventing fire or injury.
Why would a ground wire not trip?
Because the wire touches the metal enclosure, the circuit would not be broken and the circuit breaker would not trip to cut power to the circuit. If you touched the metal, you would be shocked. With a ground wire, the earth would draw infinite current from the utility company.

What is a grounding pathway?
The grounding pathway is generally formed by a system of bare copper wires that connect to every device and every metal electrical box in your home. In standard sheathed NM cable, this bare copper wire is included along with the insulated conducting wires inside the cable. The bare copper grounding wires terminate in a grounding bar in your main service panel, and that grounding bar is in turn connected to a grounding rod driven deep into the earth outside your home. This grounding system provides a path of least resistance for electricity to follow back to ground should a break in the wiring system allow electricity to "leak" out of the preferred system of black and white circuit wires.

Since electrical current always flows along the path of least resistance, you can get electrocuted if you ever use any ungrounded device. In an electrical system that is fully grounded, misdirected or excess current is channeled into the ground connection and then into the ground. If there is no ground connection or a poor ground connection in the house, electricity could travel through your body to the ground. In this case you would end up becoming the ground connection – a condition that can lead to serious injury or also death.
