What is Supplementary Bonding?
Supplementary Bonding is the process of combining metal parts together to create a single electrical path. Furthermore, this is often done to improve the safety and reliability of an electrical system. In most cases, supplementary bonding is used as a backup in case of an electrical fault. By creating a single path for electricity to flow, it is less likely that dangerous sparks will occur. In this blog post, we will discuss the basics of supplementary bonding and how it can be used to improve safety in your home or office.
Supplementary Bonding Conductors
Supplementary bonding conductors are metal parts that are used to create a single electrical path. They are typically made of copper or aluminum, and are used to connect metal parts that would otherwise not be able to connect. For example, if you have a metal fence surrounding your property, you can use supplementary bonding conductors to connect the fence to the main earth connection point. This will create a single path for electricity to flow and help prevent dangerous sparks from occurring.
The main earth bonding point is the most important part of a supplementary bonding system. In addition, it is a piece of metal that is connected to the main electrical system and provides a path for electricity to flow in case of an emergency. In most cases, the main earth bonding point will be a piece of metal buried in the ground near your home or office. You can check with your local electrical provider to see what the main earth bonding point is in your area.
If you are not sure where the main earth bonding point is, you can use a metal detector to find it. Metal detectors work by sending out a magnetic field and detecting any metal objects that are nearby.
Difference between cross bonding and supplementary bonding
Cross and supplementary bonding are both methods of improving safety in an electrical system. However, there are some important differences between the two methods.
Cross bonding is a method of connecting two or more electrical systems together. This is done to create a single path for electricity to flow in case of an emergency. By connecting multiple systems together, it is less likely that dangerous sparks will occur.
Supplementary bonding is the process of joining metal parts together to create a single electrical path. This is often done to improve the safety and reliability of an electrical system. In most cases, supplementary bonding is used as a backup in case of an electrical fault.
What requires bonding?
Any metal object that is not electrically connected can be bonded . This includes fences, gates, railings, and other metal objects around your property. Furthermore, it is important to remember that supplementary bonding is a backup system and should not be used as the primary means of electrical safety. However, always consult with a qualified electrician to ensure that your electrical system is safe and up to code.
Primarily, these can include the following
Exposed structures within the building
Pipework and Ducting
Water Pipes
AC and Heating Systems
Gas Pipes
Visibility of supplementary bonding
One of the benefits is that it is often invisible to the naked eye. Therefore, this means that you can have a safe and reliable electrical system without having to worry about unsightly wires and cables. In addition, in most cases, it can be done quickly and easily, without having to disturb your property or disrupt your daily routine.
If you are considering this electrical work for your home or office, be sure to consult with a qualified electrician. They will be able to assess your property and recommend the best course of action. Thanks for reading!
