Electrical Safety: Proper Grounding

Electrical Safety

Electrical currents can be very dangerous unless they are properly grounded. There are many ways to do this and if you will be completing some electrical work in the near future or are currently working on a project, you should make sure that you have the proper materials necessary in order to earth the electrical current.

Very often one of the easiest ways to ground an electrical current is to attach it to a copper earth rod which is buried under ground. The strength of the electrical current you are dealing with has a lot to do with determining the size of the copper ground rod that you need. The most common sizes are 3/8” and 5/8” copper rod. In order to ensure that the wires maintain their contact with the ground rod it is also important to use properly sized earth clamps. These clamps use a screw type mechanism to keep the wire constantly in contact with the earth rod and are usually sized to match the common earth rod sizes.
If you need to bury a long length of earth rod in order to meet the needs of a particular site there are also couplers that can be used to connect lengths of earth rod.

Galvanized earth rods are another nice option for grounding. Though they tend to be a bit more expensive than the copper earth rods, they are rated to last longer. It is a good idea to read up on the specific grounding requirements for your locale before deciding on what exactly to purchase to complete your electrical project.

If you are involved with a new construction project at some point in time there will be an electrical inspection and if you want that process to go as smoothly as possible, it is important to plan out the earthing process before the actual construction gets under way. Electrical blueprints provide a good idea of the placement of electrical boxes, where the wires run and where the earthing points should be located.

Another important consideration is the electrical sleeving that serves as a protection between the electrical wires and the surrounding environment. Electrical sleeving is available in a variety of sizes as well as different levels of insulation that may be required, depending on where the wiring is located. The braiding process is very important to the quality of the sleeving that is produced and if you really want to protect your electrical work and make sure that it is operated problem free for many years to come, you will choose good quality sleeving.

Proper earthing protects people from dangerous shocks and also serves to protect any electrical equipment that is connected to the circuit. Earthing also helps to dissipate excess voltage that may build up over time and cause damage to the circuit. They also help to avoid buildup of static electricity, which can be quite dangerous. Proper earthing can make the difference between a safe electrical circuit and a dangerous one. With good planning and forethought you can make sure that you have all of the materials in place to properly ground any electrical circuits you are working on.
