They are usually liable for the original creations and managing the particular installation.

Generally speaking, an HVAC engineer in North Park Chicago will probably be seen working at a design business or in a consulting firm based on their years of skill. Most engineers shift to a consulting job while they grow older and gain a better understanding of what is required of them.

Comparing HVAC Engineer vs HVAC Technician

HVAC Technician and HVAC Engineer are often mistaken for the other. Nevertheless, they have separate job functions when it comes to managing HVAC systems. It’s crucial that you are aware of the variance both as being a client and as a specialist

An HVAC technician in North Park Chicago is a more active job, which means they are generally seen on the way to a client’s building to inspect their present system. They often keep up with the installations, repairs, and general maintenance which is required from time to time. Almost all of their effort is done in conjunction with the client, which implies they need to understand how to interact with people in the correct manner.

Having an HVAC engineer, they are accountable for designing a brand new HVAC system and making certain it fits just what a client is after. It must fit precisely what the home owner wants whether or not it involves their setup, property, or anything else of new system. Also, they are introduced to refer to HVAC designs to be certain everything is consistent with today’s standards. For this reason they could end up passing time in consulting tasks or at neighborhood engineering businesses. That is basically the difference between both of these career paths; HVAC Technician vs HVAC Engineer. There is only so much you can save this page if you would like additional details on the HVAC Engineering services in North Park Chicago, Illinois by NY Engineers we invite you to take a look at our North Park Chicago Construction Administration blog.

Selecting the Right Type of Electrical Raceway for your Architectural Engineering Project: Nonmetallic Conduit Options

Construction Engineering Pdf

Our previous article covered the main types of metallic conduit for electrical conductors, and now we will discuss nonmetallic conduit and its applications in architectural engineering and other engineering areas. Nonmetallic conduit is normally the more affordable option, providing improved electrical isolation and corrosion resistance, while reducing the degree of physical protection.

Like with metallic conduit, all electrical installations must be according to the NFPA National Electric Code and local electrical codes. Conductors are not intended for unprotected installation, except for specific types that include metallic armor or polymer sheathing.

Keep in mind that this article is no replacement for electrical codes; the technical information provided here is very general. When working with engineering projects that involve electrical installations, you should check the specific code requirements for each application.

Rigid Polyvinyl Chloride Conduit (PVC)

PVC is possibly the most common type of nonmetallic conduit used in architectural engineering projects, being lightweight and affordable, while offering decent mechanical resistance for its low weight. In addition, it is virtually unaffected by humidity and corrosion, and is also an electrical insulator. However, the insulating properties of PVC are both a benefit and a disadvantage: the conduit itself cannot be electrified, but a grounding conductor becomes mandatory as a result, while metallic conduit can be used as both raceway and grounding in various applications.

PVC also offers features that simplify installation: it can be heated for quick manual bends, recovering its rigidity once it cools down. In addition, its low weight simplifies handling, and the conduit is easy to cut. PVC fittings are unthreaded and designed for slip-on installation, using solvent cements. PVC pull boxes also bring the reduced weight advantage, making them easier to handle and install.

This type of nonmetallic conduit is available with three different wall thicknesses: Schedule 20 is the thinnest, Schedule 40 is intermediate, and Schedule 80 is the thickest. Trade sizes range from ½” to 6”.

  • Schedule 20 PVC, with its thin walls, is not approved by the NEC for electrical installations. Therefore, it is used mostly in communication systems.
  • Schedule 40 PVC is the general-purpose option, adapting to a wide range of applications.
  • Schedule 80 PVC is used there conduit is exposed to physical damage. It is more expensive than Schedule 40, but its added strength increases the allowed applications.

The use of PVC conduit is not allowed in hazardous locations, areas where the ambient temperature exceeds 50°C (122°F), or applications where conductor insulation temperature exceeds the rated temperature of PVC. When used for lighting circuits, PVC cannot be used as physical support to hang lighting fixtures. Although the code does not prohibit its use with low ambient temperatures, consider that extreme cold can make PVC brittle, offering reduced protection for conductors.

High Density Polyethylene Conduit (HDPE)

HDPE is a type of nonmetallic conduit for applications where the circuit is buried or encased in concrete. It is not approved for indoor use or for exposed installation. Like PVC conduit, HDPE is not allowed in hazardous locations unless the code makes a direct exception, and it subject to the same ambient temperature and conductor insulation temperature limitations. The approved HDPE trade sizes range from ½” to 6”.

Reinforced Thermosetting Resin Conduit (RTRC)

RTRC is more commonly known as fiberglass conduit. Its applications are very similar to those of Schedule 40 PVC, but there is one key advantage: PVC can become brittle when exposed to very cold weather, while RTRC conserves its mechanical properties. RTRC is suitable for exposed or buried installation, indoor or outdoor use, and is unaffected by humidity and corrosion.

The applications where RTRC is not allowed are similar to those of Schedule 40 PVC: hazardous locations, luminaire support, and areas where it is exposed to physical damage or high temperature. Like with PVC and HDPE, trade sizes range from ½” to 6”.

Liquidtight Flexible Nonmetallic Conduit (LFNC)

LFNC has a self-explanatory name: it is a type of nonmetallic conduit intended for connections and cable runs with obstacles that are difficult to bypass with rigid conduit. LFNC is a versatile option, approved for various indoor and outdoor applications. Usage is not allowed where it will be exposed to damage, in hazardous locations, or if temperatures exceed conduit ratings. Like PVC, LFNC is vulnerable to extreme cold: it may become brittle, losing its flexibility. Unless codes make an exception, LFNC should not be used in runs longer than 6 ft or with circuits above 600V. Approved trade sizes range from ⅜” to 4”.

Electrical Nonmetallic Tubing (ENT)

ENT has similar applications to LFNC, but can be used for runs longer than 6 feet. In indoor locations, ENT can be either exposed or concealed. It resists moisture and corrosion, but can only be used outdoors if encased in concrete or protected from sunlight. Direct burial is not allowed, and it can only be installed exposed to the sun if specified as sunlight resistant.

ENT trade sizes range from ½” to 1”, and it is subject to the same usage restrictions that apply for many other types of nonmetallic conduit: hazardous locations, high temperatures and luminaire support.

Additional Recommendations from an Architectural Engineering Professional

Although each application is unique, non-metallic conduit generally offers a cost advantage over metallic conduit, giving up on some physical protection. However, keep in mind that metallic conduit may be mandatory in various architectural engineering applications; for example, the most demanding environments typically require rigid metal conduit (RMC) or intermediate metal conduit (IMC).

To achieve the best results in electrical installations, working with qualified professionals is highly recommended. In new construction, you can achieve drastic cost reductions with smart design decisions. For example, energy efficiency reduces the electrical load, which in turn reduces conductor and conduit diameter.
