Romex (presented in yellow above) is the trade name for a form of electrical conductor through non-metallic sheapoint that is frequently provided as residential branch wiring. In fact, Romex will certainly be the most common cable you'll usage in wiring a home. The following are a few standard facts around Romex wiring:
Romex ™ is a prevalent form of residential wiring that iscategorized by the National Electrical Code (NEC) as underground feeder (UF) or non-metallic sheathed cable (NM and NMC).NM and also NMC conductors are created of 2 or more insulated conductors had in a non-metallic sheath. The coating on NMC cable is non-conducting, flame-resistant and also moisture-resistant. Unfavor various other cables frequently found in dwellings, they are allowed in damp atmospheres, such as basements. Underground feeder conductors show up comparable to NM and NMC cables other than thatUF cables contain a solid plastic core and also cannot be “rolled” between fingers.
The following NEC regulations use to Romex conductors:They should be defended, secured and also clamped to device boxes, junction boxes and fixtures. Support tools that may damages the cables, such as bent nails and also overpushed staples, are not allowed.NM and also NMC cables have to be secured at intervals that perform not exceed 4½ feet, and they must be secured within 12 inches of junction boxes and panels to which they are attached. Cables that do not comply through this rule have the right to sag and also are fragile to damage. They are intfinished as irreversible wiring in houses and also should not be offered as asubstitute for appliance wiring or extension cords.
Romex is offered for most lighting and also outlet circuits in your house. Romex will certainly be labeled with "12-2" or "12-3". The first number indicates the gauge of the wire. You options are frequently 10, 12, or 14 gauge. The second number suggests the variety of conductors. A 12-2 Romex will have a black(hot) and also a white(neutral) wire as well as an unsheathed copper wire for ground. A 12-3 Romex will certainly have a black(hot), red(hot), white(neutral), and bare copper. The red on a 12-3 is supplied for three-method light switches which are spanned later.
12 gauge Romex is rated for 20 Amps and is commonly yellow jacketed. 14 gauge Romex is still provided in some applications and is rated for 15 Amps and also is grey jacketed. 10 gauge Romex has actually an orange jacket and is offered for water heaters or garments driers. For our cabin, we used 12 gauge Romex for all of the outlets and lighting circuits. This is very prevalent now-a-days fairly than running 14 gauge. In enhancement to Romex, wiring a house likewise calls for a few larger gauge wires for high power appliances. Your air conditioner or electrical stove would fall into this category. The table listed below list some prevalent wire forms and rated amperage for wiring a residence.
|Wire Gauge or Type||Rated Amperage||Common Uses|
|14-2 Romex||15 A||Lighting Circuits|
|12-2 Romex||20 A||Lighting and Outlet Circuits, refrigerator|
|10-2 Romex||30 A||Electric water heater, baseboard heaters|
|10-3 Romex||30 A||Electric Clothes Dryer|
|6/3 Cu Range Cable||50 A||Range, Heatpump, On-Demand also Electric Water heater|
|2 Gauge Copper||100 A||Central Electric Heat|
|AL 1/0 SER||100 A||Aluminum 1/0-1/0-1/0-2 Service Feeder wire for 100 A breake panel|
|AL 4/0 SER||200 A||Aluminum 4/0-4/0-4/0-2/0 Service feeder wire for 200A breaker panel|
