Electrical ladder drawings are still one of the common and reliable tools used to troubleshoot equipment when it fails. As with any good troubleshooting tool, one must be familiar with its basic features to make the most of the diagram in the field. In other words, possessing a basic understanding of how the drawing is laid out — as well as the meaning of numbers and symbols found on the schematic — will make you that much more seasoned as a maintenance professional.
There are typically two distinct parts of a ladder drawing: the power component and the control component. The power portion consists of items such as the motor, motor starter contacts and overloads, disconnect(s), and protective devices (fuses and circuit breakers). The control part encompasses items that make the power components do their work. For this discussion, we'll focus on the control portion of the drawing. Let's take a look at the most common components.
