It’s absolutely vital that anyone who reads an electrical blueprint can fully understand it down to the last detail so that they can follow its instructions competently and exactly. Sound complicated? It is, but none of these things can just be glossed over.

Know the National Electrical Code (NEC) like the back of your hand.
Be able to identify critical nodes (points at which many separate wires connect which are subject to significantly more stress than most).Understand the flow of the circuit and how the power will be distributed across the lines.Be extremely familiar with all symbols and their meanings (some are very similar, but mix up a pre-set resistor and a variable resistor and you’ll be sorry!).To read an electrical blueprint, you should, among other things: Accessing all this information can be quite demanding, since a fair amount of specialized knowledge is required. Once a designer has laid out all wiring, connections, and other important elements, the pictorial instructions of the blueprint must be followed to the letter. Becoming Literate in Electrical Blueprints Deciding how much power the wiring will be able to deliver to each part of the building and where the outlets can most easily and conveniently be placed are all conundrums that are worked out in the process of drafting the blueprint. They involve different considerations than traditional blueprints instead of starting mostly from scratch, the designer must work within the given parameters of the structure to create the safest, most useful electrical system possible. These documents lay out the wiring and connections that deliver electricity throughout the building and ensure that this infrastructure will be compliant with all current codes and bylaws. These blueprints can be difficult for industry outsiders to grasp.

A closer look at the annotations lets you see all the mathematical details that keep the building standing and solid, and most of these are denoted with clear markers that can be decoded with the accompanying legend.Ĭonstruction workers frequently consult blueprints as they build to make sure that their work isn’t deviating from the overall design, and the Bureau of Labor Statistics (BLS) states that most of these workers have little to no formal training in their industry – it is assumed that they will soon figure out how to parse these blueprints with a little practice.Įlectrical blueprints, however, are a different story there are many specialized aspects to them. If you’re already familiar with the concept of space and dimensions, you get the gist of what the blueprint is trying to tell you just by glancing at it. While they’re still specialized documents, it usually isn’t too hard to read standard blueprints as a layperson. Electrical blueprint reading isn’t something you just pick up on the job – it’s a skill that requires a knowledge and understanding to fully master. Chief among them is their level of accessibility. The two types of plans differ in many significant ways. General blueprints are a well-known and integral part of construction, but their less-prominent counterpart, electrical blueprints, are just as important.
