The name “Romex” comes from the two main components of the cable: rubber insulation and metallic sheathing. <\/p>\n\n\n\n
Over the years, Romex has become the most common type of wiring used in residential and commercial construction. <\/p>\n\n\n\n
There are certain restrictions on where it can be used due to safety and fire codes. <\/strong><\/p>\n\n\n\n We\u2019ll look at these in detail so you can better understand when Romex is allowed and when it isn\u2019t.<\/p>\n\n\n\n Romex is a type of electrical wire commonly used in residential and commercial buildings. <\/p>\n\n\n\n Despite its popularity, the National Electrical Code (NEC) <\/a>does not allow Romex to be used in certain situations. <\/strong><\/p>\n\n\n\n Romex is not allowed outdoors because it is not water-resistant and can become damaged if exposed to moisture. <\/a><\/p>\n\n\n\n Additionally, Romex cannot be used in residential homes that are more than three stories tall. <\/a><\/p>\n\n\n\n Romex is also not allowed to be run exposed or in conduit due to safety concerns. <\/p>\n\n\n\n However, Romex can be used in NYC, as well as commercial buildings and garages under some restrictions. <\/p>\n\n\n\n When installing Romex, it must be supported at regular intervals to ensure the wires do not become damaged or create a fire hazard.<\/p>\n\n\n\n Romex is not allowed in residential homes <\/a>that are more than three stories high. <\/strong><\/p>\n\n\n\n This is according to the National Electrical Code and the NEC, which state that Romex conductors cannot be used in residences higher than 3 stories, making it illegal to use them in this context. <\/p>\n\n\n\n Furthermore, Romex is not allowed to be attached across the surface of framing members as it poses a significant fire hazard. <\/p>\n\n\n\n This means that any wiring done in these situations must be done with other wiring methods such as conduit<\/a> or armored cable. <\/p>\n\n\n\n Additionally, Romex should not be run through holes bored into exposed framing members as this can also create a fire hazard.<\/p>\n\n\n\n Romex is a popular type of electrical wire used in residential and commercial applications. <\/p>\n\n\n\n It is allowed for branch circuit wiring in homes and commercial buildings that are no more than three stories high, according to the National Electrical Code. <\/strong><\/p>\n\n\n\n Romex can also be used in garages and other exposed locations,<\/a> but it must be securely fastened to framing members or other supports. <\/p>\n\n\n\n In addition, Romex is allowed to be run through holes bored in framing members, but it cannot be attached across them. <\/p>\n\n\n\n When running Romex through conduit<\/a>, however, it must be installed in a manner that prevents damage to the insulation. <\/p>\n\n\n\n With proper installation and adherence to safety regulations, Romex can be a great option for wiring projects.<\/p>\n\n\n\n In New York City, Romex is not allowed in buildings that exceed three stories. <\/p>\n\n\n\n However, it is legal to use in residential applications that do not exceed three stories. <\/strong><\/p>\n\n\n\n It must be protected from risk of damage, water, and sunlight. <\/p>\n\n\n\n In the event of wanting to tear down an apartment building, Romex may be used. <\/p>\n\n\n\n Additionally, it cannot be run exposed or in conduit. In Chicago and other cities, Romex may be subject to different laws and regulations. <\/p>\n\n\n\n It is important to always check local codes when using Romex for wiring purposes<\/a>.<\/p>\n\n\n\n Romex is allowed in commercial buildings up to the third floor. <\/strong><\/p>\n\n\n\n It does not matter if the structure is residential or commercial, as long as it is a type III, IV, or V building. <\/a><\/p>\n\n\n\n However, 334.12(A)(1) of the 2002 NEC does not allow romex as open runs above drop ceilings in other than one & two family and multifamily dwellings. <\/p>\n\n\n\n Though some localities may prohibit it, California allows it. <\/p>\n\n\n\n Therefore, Romex can be used in commercial buildings within the regulations set by local authorities.<\/p>\n\n\n\n No, Romex should never be exposed in a garage. <\/a><\/strong><\/p>\n\n\n\n For safety reasons, all Romex wiring should be properly covered by conduit or raceways. <\/p>\n\n\n\n This is especially important in areas where there is potential for physical damage from outside sources, such as a garage. <\/p>\n\n\n\n If you’re running Romex through studs or joists, it must be protected by a sleeve or conduit. <\/p>\n\n\n\n In addition, Romex must not be attached across exposed framing members. <\/p>\n\n\n\n If you are running it through holes bored in the centers of exposed framing members, then it must be covered with an approved material. <\/p>\n\n\n\n By following these guidelines and using the appropriate materials, you can ensure that your Romex wiring remains safe and secure.<\/p>\n\n\n\n No, Romex wiring should not be run exposed. <\/strong><\/p>\n\n\n\n Code and common sense both dictate that Romex must run through conduits if it is to be used in residential houses. <\/p>\n\n\n\n The National Electrical Code 2011 requires that NM cable be in conduit <\/a>when protection from physical damage is required. <\/p>\n\n\n\n It is also not allowed to be attached across the framing members of exposed wall studs either. <\/p>\n\n\n\n It is important to note that while it is allowable for NM cable to run through holes <\/a>bored in the centers of exposed framing members, it should never be left exposed in a residential house where the wiring may be subject to physical damage or accidental contact.<\/p>\n\n\n\n The NEC calls for all non-metallic wires to be used in conduits to protect them from physical damage and reduce the risk of shock. <\/p>\n\n\n\n Romex is a non-metallic wire, but it is somewhat stiff and difficult to run through a conduit.<\/a> <\/strong><\/p>\n\n\n\n If Romex is not installed correctly, it can cause a safety hazard due to the exposed wire becoming tangled or pinched. <\/p>\n\n\n\n Additionally, Romex does not offer the same level of protection that metal conduit does, which is why the NEC requires metal conduit<\/a> for certain applications. <\/p>\n\n\n\n For these reasons, running Romex in a conduit<\/a> is generally not allowed and can be dangerous.<\/p>\n\n\n\n In Chicago, Romex is illegal due to the city’s strict electrical code standards. <\/p>\n\n\n\n Cook County, which includes Chicago, requires all electric wiring<\/a> to be done with EMT (electrical metallic tubing). or rigid metal conduit.<\/strong><\/p>\n\n\n\n The authority having jurisdiction shall approve electrical equipment for installation and use. Electrical Conductor Insulation and Identification: Conductors shall be of copper or aluminum. Bare copper conductors<\/p>\n\n\n\n The surrounding counties may be able to use Romex, but Chicago and most of the suburbs around it do not permit its use. <\/p>\n\n\n\n Romex wiring is safe and approved by the National Electrical Code when installed correctly, but it is not allowed in the city of Chicago.<\/p>\n\n\n\n Romex should not be run directly underground<\/a>, as it is not designed to be used in this manner.<\/strong><\/p>\n\n\n\n However, it can be run through holes bored in the framing members of a house and left exposed. <\/p>\n\n\n\n The Romex must also have proper support, such as straps or cable clamps. At least every 4-1\/2 feet, and within 12 inches of any outlet box or junction box. <\/p>\n\n\n\n When running Romex outside or under a house, be sure to check with local building codes for additional safety requirements.<\/p>\n\n\n\n When it comes to supporting Romex, the National Electrical Code (NEC) is very specific. <\/p>\n\n\n\n Romex must be supported and secured by staples<\/a>, cable ties, straps, hangers, or similar approved devices.<\/strong><\/p>\n\n\n\n If run through holes <\/a>bored in the centers of exposed framing members. It must not be attached across the face of the member. <\/p>\n\n\n\n Furthermore, when running Romex in wet or damp locations<\/a> such as basements and garages. It must be installed within conduit to protect it from moisture. <\/p>\n\n\n\nIs Romex Illegal to Use?<\/h2>\n\n\n\n
