Moreover, you can use it in the unfinished areas, such as attics and basements.
This article will enlist all the areas where electrical conduits are necessary and give you a more detailed insight into electrical conduits usage.
Along with that, we will also explore the different types of conduits and where you can use them. Electrical conduits can be an essential part of electrical wiring and systems within or outside our homes. As mentioned above, conduits protect the electrical wires by encasing them, providing them with an extra layer for safety, and preventing them from getting damaged or wet. Exposed cables or electrical wires can be dangerous.
Thus, by encasing these wires within a tube, such as a conduit, you can protect wiring against harsh weather conditions and external factors that might threaten the wires. Conduits can also be highly beneficial when used indoors for exposed wires in areas such as attics and basements.
The main benefit of safeguarding your wires with conduits indoors is to protect them from pesky rodents or mice that may eat them away.
Conduits are used to provide extra protection for electrical wires. Conduit protects both humans and the electrical wiring to prevent wires from pulling loose and creating shock hazards. Almost all conduits are available in different sizes. Besides protecting your wires, they are also great for keeping all your wires organized. If you feel that the wiring in your home looks messy with too many stray wires, conduit can help.
Conduit allows you to organize wires, protect your family, and meet local electrical codes. Conduits will make your home look cleaner as fewer wires will be exposed and help you when you have to fix any of the wires in case of a short circuit.
Another benefit of using conduits within your home is that it makes replacing or fixing the wires easier. More than three types of conduits are available in the market, but FMC, PVC, and plastic conduit are the most popular ones. Conduits are made with several materials that successfully provide sufficient protection to exposed wires within any structure or building.
Different types of conduits, therefore, are used for various requirements and different areas. Among the types of conduits on the market, the Flexible Metal Conduit FMC is well-known for protecting wires in dry and exposed areas within a building.
If you want to protect exposed, short wirings in a tight area, such as water heaters, FMCs will be the right choice for this purpose. Run NM wires throughout the shed and tie them through electrical wire boxes. Attach any desired fixtures in the shed or on outside and run wire as needed.
Tie in NM wires from fixtures and receptacles into sub panel breakers as needed. Turn off the electricity inside the home at the main breaker panel. Re: Exposed romex NM cable is permitted to be run exposed on the surface of the building finish. If subject to physical damage then it requires supplemental protection. The term subject to physical damage is not defined by the NEC so it becomes an interpretative issue.
In a house or a finished garage , electrical cable is protected from damage by permanent wallcoverings like drywall, plaster or even wood, but that's not the case in an unfinished garage. The key to safe, code-compliant exposed wiring is to use the framing members to protect and support the wires.
While the National Electrical Code does not expressly forbid inserting NM cable inside conduit , in practice, it is very difficult to do so, and very few professional electricians will do such an installation. THHN wires are relatively inexpensive and are much easier to run through conduit. Romex is allowed in conduit , length is not an issue. Romex is not allowed in wet locations.
The inside of conduit in a wet location is considered a wet location. You can run electrical wire outside to nearly any location. Although some types of electrical cable do not have to be enclosed in conduit for outside installation, enclosing any exposed cable is a good idea. Schedule 40 polyvinyl chloride PVC conduit for electricity is gray and is rated for sunlight resistance. The most common type of cable used in home wiring is non-metallic NM , or Romex, cable.
While NM cable can be run inside conduit, this is seldom done. However, your electrical wires can become dangerous over time if you don't take necessary safety precautions. Live wires transmit electrical current which, when exposed , can even cause electric shocks or fires. Typical EMT Type conduit will resist rust for a few years. It is however inevitable that it will rust. On the other hand there have been times when the conduit has rusted on parts of its surface having been exposed to the outdoor elements for one or two seasons.
So while you may be able to use schedule 40 for the entire run, you'll have to use schedule 80 through any areas where the AHJ deems the conduit is exposed to physical damage. Nonmetallic conduit is typically made from PVC and is a good choice for outdoor residential applications.
