According to the 2008 National Electrical Code book (US NEC):
Section 334.10 Uses Permitted. Type NM (NM is the proper term for the brand name product Romex) cables can be used in:
(1) One- and two-family dwellings.
(2) Multifamily dwellings when built as a Type III, IV, or V construction
(3) Other structures when built as Types III, IV, and V
(4) Cable trays in Type III, IV, or V structures
[Types of building construction and occupancy classification are defined in NFPA 220-2006, Standard on Types of Building Construction]
So yes, Romex can be used in a commercial building. There are other code sections that may apply to your particular installation, if you are unfamiliar with the code book and are doing electrical work you should take a class on the NEC. An improper installation could lead to personal injury or property damage. Electrical work should only be done by a qualified person. The NEC defines a qualified person as "One who has skills and knowledge related to the construction and operation of the electrical equipment and installations and has received safety training to recognize and avoid the hazards involved."
Yes unless there were some overarching electric code reason why conduit was used in lieu of Romex. if in doubt ask an electrician.
What kind of wire? If it's a power wire, why is the place wired with conduit? Commercial buildings must put all power wiring in conduit, so if you're planning to run romex in a commercial building, the answer would be "no", it's not permissible. If it's data wire, note that there may be some "crossover" interference if the data wire follows a power wire for very much distance. It's usually not a problem to cross a conduit and tie to it, but it's generally recommended that you not tie data cable to conduit.
You need no conduit on a residential home using Romex wiring with wooden studs. For a 15 amp circuit use 14/2 wire with a 15 amp breaker. This can only be used in bedrooms, living rooms, and dining areas. All other areas of the home require 12/2 wiring with a 20 amp breaker.
If you are talking about #6 building wire, it needs to have mechanical protection. This means that it has to be run in conduit. If you are talking about #6 cable set like Romex, then it only has to have mechanically protection below a five foot elevation from the garage's finished floor. If the wall that the cable set is running in is going to be finished with drywall or plywood then that is considered protected.
In Westchester County, New York, the use of Romex cable (NM cable) is generally permitted for residential wiring, provided it complies with the National Electrical Code (NEC) and local amendments. However, specific applications, such as in certain commercial or multifamily buildings, may have restrictions. It's essential to check with local building codes and regulations or consult a licensed electrician for guidance on compliance. Always ensure that any electrical work meets safety standards.
No, Romex wiring cannot be run in conduit as it is not designed or approved for use in conduit.
The advantages of using Romex conduit for electrical wiring installations include easier installation, protection of wires from damage, and compliance with building codes.
Yes, it is generally not permissible to run Romex cable in conduit because Romex is already insulated and designed for use without additional protection. Running Romex in conduit can lead to overheating and potential fire hazards.
Yes, it is generally not recommended to put Romex wiring inside conduit as it can cause overheating and potential safety hazards. Romex wiring is typically designed for use without conduit.
No, Romex cable is not allowed to be run inside conduit. Romex cable is intended to be used in exposed or concealed applications within buildings. If conduit is used, it should contain individual THHN/THWN wires instead of Romex cable.
The best practice for installing Romex in conduit is to not do it. Romex, which is a type of non-metallic cable, should not be installed in conduit as it can lead to overheating and potential fire hazards. Instead, use individual THHN or THWN wires in conduit for safety and compliance with electrical codes.
Yes unless there were some overarching electric code reason why conduit was used in lieu of Romex. if in doubt ask an electrician.
Romex cable cannot be run in conduit because it is not designed to be used in that way. Romex is a type of non-metallic sheathed cable that already has its own protective outer jacket. Running it in conduit can cause overheating and damage to the cable, potentially leading to a fire hazard. It is important to follow the manufacturer's guidelines for proper installation of Romex cable.

THHN is a heat resistant thermoplastic insulated conductor, usually a single conductor. Romex is a brand name for a nonmetallic sheathed cable, it has multiple conductors inside, the insulated ones are insulated with THHN insulation.
No, it is not safe for Romex wiring to be exposed in a residential setting as it can pose a risk of electrical shock or fire hazard. It should be properly installed and protected within walls or conduit.
