Electrical Grounding and Bonding Educational PDF Document
My name is Dusten Huebner, I work in the oil patch as an industrial electrician in Alberta, Canada constructing large oilfield facilities, well sites, performing plant maintenance and much much more.
In my time in the field, I’ve seen many unique situations and have heard many stories, tips and warnings during my training. It gives me great pleasure and satisfaction sharing all I have learned in all my years of experience in the field.
If you want to know more about grounding and bonding, you’re definitely in the right place. Whether you're new to the game or looking to further your knowledge in the electrical world, I have some great information for you on grounding and bonding so let’s get started.
At a fundamental level, electricity is simply a difference in energy between two points. Usually, that difference is measured relative to the earth, which is where the term grounding comes from. In order for the difference in energy, also known as potential, to do useful work for us it generally needs to be kept isolated from ground. Electricity will always take the path of least resistance back to ground, so if the easiest path for it to take is through our motor, heater, light, or anything else we want to power, then our electrical system will continue to operate normally. Given the opportunity though, faults can occur with destructive consequences.
What is Grounding?
Simply put, grounding is the way that parts of an electrical circuit or system are connected to the earth. Grounding includes any grounding conductors, grounding electrodes, and the connections used to securely fasten these parts together. For our circuit protection devices to work properly, the connection to ground must be as low resistance as possible, so grounding electrodes must have as much surface area in contact with the ground as possible. These grounding electrodes can include buried metal water piping, ground rods, ground plates, or bare ground wire grids.
What is Electrical Bonding?
While grounding and bonding might seem like the same thing, they have some very important differences. Electrical bonding is the practice of connecting metallic objects that may be exposed to electrical faults or induced voltages to the grounding conductor. This ensures that in the event of a fault the current will have a low resistance path to take to trip the overcurrent devices as quickly as possible, as well as providing a path for static electricity and induced voltages to drain out. Bonding conductors must also be sized so that they can safely carry the largest possible load that might occur in a fault condition.
