What is Exposed electrical conduit? [Pros and Cons Included]

Most commercial and institutional structures, as well as certain residential uses, choose exposed electrical conduit as their preferred option. The various varieties of “exposed electrical conduit” that are accessible, their advantages and disadvantages, and some general guidelines to follow while dealing with utilizing exposed electrical conduit will all be covered on this page.

Exposed electrical conduit: what is it?

A cabling system known as an exposed electrical conduit involves running the electrical wires throughout a metallic or plastic tube that serves as protection. The conduit would then be put on the exterior of the ceilings and walls as opposed to being concealed by drywall or even other finishing materials.

Which electrical conduit kinds are there that are exposed?

Metallic Conduit

• The most popular conduit used throughout commercial and business structures is metal, which is often constructed of either steel or aluminum. It is corrosion-resistant, sturdy, and robust.

PVC Conduit

• Plastics PVC conduit becomes less costly than metallic conduit since it is comprised of plastic. It is corrosion-resistant, inexpensive, and simple to install.

Flexible Conduit

• Flexible conduit is comprised of a malleable substance, such as metals or plastics, and is intended to be bent over sharp angles or curves.

EMT (Electrical Metallic Tubing)

• Compact, simple to construct, and with a smooth steel material outside, EMT is a metal conduit.

RMC (Rigid Metal Conduit)

• RMC would be a robust steel tube with a thick-walled iron conduit.

IMC (Intermediate Metal Conduit)

• Comparable to EMT but with larger walls, IMC is a different kind of compact, galvanized metallic conduit that is frequently used in corporate, institutional, including household structures.

Where can exposed electrical conduits be used?

Industrial establishments

• Due to its strength and ability to endure the extreme conditions present in these settings, an exposed conduit is frequently utilized in industrial sites.

Commercial structures

• Since it is affordable and simple to construct, an exposed conduit would be a preferred option for offices, retail establishments, as well as other commercial structures.

Exterior usage

• Since the exposed conduit is weather-resistant and simple to fix, it is frequently utilized in outdoor locations like parking areas, signage, and billboards.

Shopping centers

• Additionally, store exhibits, lighting, music, and safety systems are all powered via exposed conduits within retail settings.

Garages as well as workspaces used by homeowners

• Due to its simplicity in installation and maintenance, an exposed conduit would be a popular option for garages as well as workshops.

Conferences and exhibits

• Due to its simplicity of installation and modification, an exposed conduit is frequently used in exposition and convention halls. This enables quick installation and teardown of portable exhibits and exhibitions.

Installation works of art

• Due to its strength and adaptability, exposed tubing is preferred for building features like lighting fixtures and statues.

What advantages can exposed electrical conduits offer?

Here are a few advantages of exposed electrical conduit.

Cost-effectiveness

• Compared to alternative wiring solutions like a hidden conduit with surface-mounted wire, the overhead electric conduit is often less costly.

Simple installation

• For residential and commercial structures, exposed conduit would be a common choice since it is reasonably simple to install.

Simple upkeep and repair

• It is simple to see issues and make adjustments as necessary since the conduit, as well as wires, are exposed.

Flexibility

• It is simple to modify and add additional circuits when an electrical conduit is exposed.

Durability

• Conduit is a robust material that can survive a period of time since it is often comprised of plastic or steel.

Aesthetics

• In order to create a visually appealing architectural feature, exposed electrical conduit might be repainted to suit the building’s inside or outside.

Safety

• The wire is given further protection by exposed conduit, which reduces its susceptibility to harm from pests, impacts, and moisture.

It’s crucial to remember that not each circumstance or style of structure calls for a visible conduit.

What problems does exposed electrical conduit have?

Among the disadvantages of exposed electrical conduits, there are the following.

Aesthetics

• Even while visible conduit could be repainted to suit the inside or outside of the building, certain individuals can find it unsightly.

A challenge to conceal

• Because exposed conduit is unsightly and could not be the best option for structures that need a more completed or polished appearance.

Possible dangers to safety

• If not placed or secured appropriately, exposed conduit might be a cause of accidents. Furthermore, the conduit may present a shock danger if it is improperly grounded.

Limited defense

• Conduit might provide some safeguards for the wire, but it doesn’t offer the same security as a hidden conduit or surface-mounted cabling.

Codes for construction

• Exposed conduit might not be permitted by some building rules, and it might not be legal in some places.

Susceptible to outside influences

• A conduit exposed to the elements is more likely to sustain harm through pests, impacts, and dampness.

Not appropriate in some settings

• In locations where moisture and other external variables might harm the conduit or cables, an exposed conduit may not be the best option.

What typical exposed electrical conduit procedures are there?

When handling exposed electrical conduits, a number of standard procedures are used.

Mounting

• Belts, clamps, and brackets are frequently used to install exposed tubes on top walls and ceilings. In order to avoid creating a hazardous situation, it is crucial to make sure the tube is placed securely.

Grounding

• In order to avoid shock dangers, exposed conduit needs to be properly insulated. In most cases, this is accomplished by joining the conduit to an earth wire or grounding rod.

Painting

• The roof of a building or internal paint colors can be used to match visible conduit. It’s crucial to utilize paint that is appropriate for the kind of conduit getting employed.

Drawing a wire

• To avoid damaging the cables, it’s crucial to draw them through exposed conduits with the correct method while installing cables.

Brake Radius

• A certain radius must be used to bend the conduit, often not just under ten times the overall conduit size, to prevent damage to cables within.

Cable stuffing

• Ensuring the conduit isn’t overloaded with cables is crucial. Wires may become broken or crimped if the conduit is overfilled.

Labeling

• For ease of tracing and maintenance, it is crucial to mark the conduit at both ends with the name of the circuit it houses.

Support

• For code compliance and to avoid drooping, the conduit should be maintained every three meters on each 90-degree curve.

Protection

• Safeguard exposed conduit against harm from outside forces, including vermin, physical effects, and humidity.

These are standard procedures that must be adhered to in compliance with both local construction rules as well as the National Electric Code (NEC).
