How are Electrical Cables Grounded?
Electrical Cables Grounded : Electrical wire grounding is a crucial step in the process of making your house safe and structurally strong. This easy precaution, which involves turning the electric current toward the earth, greatly reduces the risk of deadly collisions. We will attempt to explain why electrical grounding is essential for your home and provide instructions on how to accomplish it in this article.

Why is it important to ground electrical wires?
Electrical wires need to be grounded for a number of reasons.
Protection against electric shock
Grounding offers a way for the electricity to safely go to the ground in the event of an electrical malfunction, such as a short circuit. This prevents electric shocks should someone come into contact with a live wire in such a scenario.
Keeping fires from electrical sources at bay
Overheating cables and equipment is the cause of electrical fires. Grounding assists in the prevention of circumstances that could result in electrical fires by offering a secure conduit for surplus electricity to pass to the ground.
Safeguarding apparatus
Lightning strikes and abrupt voltage surges can quickly destroy electrical equipment. Grounding preserves the integrity of electrical systems and extends the life of equipment by preventing harm by safely sending excess current to the ground.
Ensuring appropriate functionality
Grounding is considered essential for most electrical equipment and systems, as they mostly depend on it to function properly. Particularly sensitive devices need a steady reference voltage, which grounding alone can supply.
Adherence to norms and codes
Electrical grounding is required in accordance with government-issued electrical codes and standards for residential and commercial facilities. It is imperative that these rules be followed for legal as well as safety reasons.
Methods for grounding electrical cables
The following actions are involved in grounding electrical wires:
Switch off the electricity.
First things first, cut off the circuit’s power source before doing any electrical operations. Verify with a circuit tester that the power is off, and only start operating after you are positive there are no safety risks.
Get the grounding wire ready.
For grounding purposes, bare or green copper wire is the best option. Make sure you cut the wire to the proper length, including enough slack to allow it to reach from the fixture or device to the grounding point.
Attach to the terminal for grounding.
Find the screw or grounding terminal on the gadget or in the electrical box. Next, firmly tighten the grounding screw after loosening it and wrapping the bare end of the grounding wire around it in a clockwise motion.
Linking up with the grounding electrode apparatus
An iron rod insert into the ground serves as the grounding electrode system. When installing a new system, be careful to attach the grounding wire to it. Utilizing a grounding clamp, fasten the wire to the electrode securely.
Getting Along
Make sure that all of the system’s metal components—such as conduit and metal boxes—are bonded together with grounding wires to create a continuous grounding path.
Put in GFCIs.
Ground fault circuit interrupter outlets, or GFCIs, are require in places like kitchens and bathrooms where there is a lot of water contact. These outlets offer an additional degree of security by sensing ground faults and cutting the circuit’s power when necessary.
Examine the connections.
Verify connections make sure all of the connections are tight and secure by checking and double-checking them. Both ends of the grounding wire need to be securely fasten.
Restore power and do a test.
After finishing, reactivate the power and verify that the grounding is correctly connect and operational with a circuit tester. Check to make sure all safety requirements are being fulfill as plan.
