A ladder diagram will systematically show how a piece of equipment is wired and how the electrical circuits combine to make the equipment operate successfully. It is usually drawn with the line control voltage on the left side of the page and the control neutral line on the right side of the page. Electric symbols representing actual devices are drawn in between these two lines. These circuits are like rungs in a ladder. For every control panel that is built there should be a ladder diagram. It is these ladder diagrams that electricians use to trouble shoot electrical control equipment. Without these diagrams it is nearly impossible to fine a fault in control circuitry.
A way to practice ladder safety is to read all instructions that come with the ladder. This can include selecting the right ladder for the task at hand and also making sure the weight limit is observed.
