Basics on Electrical Circuits in Construction

Basics on Electrical Circuits in Construction

There are a few basic concepts that will often be present when dealing with various electrical needs during any industrial construction project, and circuits are often on this list. For any parties who will be present during electrical work, even those who are not trained electricians, having a basic understanding of circuitry and circuit systems is helpful for both safety and project efficiency.

At Redi, we're proud to offer numerous industrial construction services for clients around Wyoming, Colorado and Nevada, from large-scale tasks like facility maintenance to specific services like electrical solutions, heavy haul trucking and more. Here are some general basics on what electrical circuits are, the kinds of circuits you may deal with during construction jobs, and a few other simple facts.

Defining Electrical Circuits

For those who have never actually heard a specific definition of circuits before, one of the more basic ones is that circuits are continuous paths for electrical current. They're a fundamental part of any building's infrastructure, with many components that will need to be managed and maintained properly at various stages in construction and operation.

Circuits can span from small electronic chips to massive power grids, and there are numerous types of circuits often used in industrial construction projects. But in their simplest sense, electrical circuits are a loop of material capable of carrying electrical power through wires and receptacles in a given building. Our next several sections will dig into more specifics.

Four Primary Types of Electrical Circuits

While there are certain sub-types of circuits, some of which we'll get into in a moment, there are four main types of electrical circuits to be aware of:

  • Closed circuit: This is the term used when a circuit has no breaks and the current can flow from one end to another. This is generally what's considered the standard for all electrical systems and applications.
  • Open circuit: This is the opposite of a closed circuit, and means that there's no power flowing through an area at a given moment. This could be due to numerous possible factors, including damaged wiring or switches that aren't toggled on.
  • Short circuit: A short circuit is the term used when current finds an unintended path to ground, one that's more convenient or efficient than the alternate path. Short circuits can be major safety hazards, but they're also often easy to fix.
  • Series circuit: A series circuit is set up in a way where all electric elements are connected end-to-end and form a single loop. These systems often utilize resistors as well, which regulate the flow of electricity and prevent it from becoming too high.

Common Circuit Components

As we noted above, there are many different types of circuits with various components that may be present depending on your specific project. Some common circuit components include:

  • Conductors: These are materials with a low resistance to electrical current, such as copper or aluminum wire.
  • Insulators: These are materials with a high resistance to electrical current, such as rubber or plastic.
  • Switches: Used to turn circuits on and off, switches can be manual or automatic and come in various types.
  • Fuses: These are safety devices that protect against short circuits by breaking the circuit when too much current is flowing through it.
  • Circuit breakers: Similar to fuses, these are automatic switches that break the circuit when an electrical overload is detected.
  • Transformers: These devices help regulate voltage and can step it up or down as needed for different components in a circuit.

AC Vs. DC Circuits

When it comes to current flow, there are two main types to be aware of: Alternating Current (AC) and Direct Current (DC). AC circuits are commonly used in power grids, where the current direction changes periodically, while DC circuits have a constant flow in one direction. Depending on your project's needs, you may need to use one or both types of circuits.

Dedicated Circuits

Finally, one particular kind of circuit that's quite common within large industrial construction projects is a dedicated circuit, which is one that provides power to a single specific appliance or device. These circuits are often required for high-power appliances like refrigeration units, HVAC systems or large machinery.

As you can see, understanding basic circuitry and the various components and types involved is important for anyone working on an industrial construction project.
