AC Vs MC Cable – What’s the Difference? If you’re new to the world of electrical cable, you may be confused as to the difference between AC and MC cables. This article will give you a clear understanding of these terms.
AC and MC cables have similar construction, but differ in terms of grounding features. MC has metal armor and a dedicated PVC jacket, while AC utilizes either a jacket combined with wire or thin strip as its grounding element.
AC Vs MC Cable
AC Cable:
- Stands for “Armored Cable”
- Has two or more insulated conductors inside a flexible metal sheath
- Typically used for branch circuits, power distribution, and lighting
- Suitable for indoor and outdoor use
- Can be installed in wet and dry locations
- May require a separate grounding conductor
- More affordable than MC Cable
MC Cable:
- Stands for “Metal-Clad Cable”
- Has two or more insulated conductors inside a spiral metal sheath
- Suitable for power and lighting circuits, feeders, and branch circuits
- Typically used in commercial, industrial, and residential settings
- More durable and resistant to damage than AC Cable
- Includes a grounding conductor for safety
- Suitable for indoor and outdoor use, but not in wet locations
- More expensive than AC Cable
In summary, AC Cable is a more affordable option used for power and lighting circuits, while MC Cable is more durable and suitable for a wider range of applications, but at a higher cost. Both types of cable can be used for indoor and outdoor installation, but their specific use may be limited depending on the location and installation requirements.
Ac Vs Mc Cable
When it comes to electrical power, two primary categories of cables exist: AC and MC. If you’re planning on upgrading your home’s electrical system, be aware of your cable options so you can make an informed decision.
Ac is the standard in most homes, but MC can have some advantages over AC. For one thing, it can be used in more places than ac and replace existing receptacles. Perhaps most impressively though, mc is water resistant – capable of withstanding more liquid damage than standard ac cables can.
MMC cable offers several advantages over its AC counterparts, the primary being its affordability. Not only that, but it can be installed quickly while still offering maximum protection from elements. And last but not least, its longevity will reduce energy bills over time – making mc cable an excellent choice for home renovation or addition projects.
AC Vs MC Cable-Is AC and MC cable the same?
Both AC and MC cable are metal-clad wires with individually insulated conductors. These cables can be utilized in both residential and commercial electrical applications.
In general, MC and Romex cables tend to be less vulnerable to damage than non-metallic (NM) cables. Furthermore, these types of cables offer more protection from environmental elements and pests that could otherwise lead to degradation over time.
MC cables differ from NM wires in that they are shielded by a jacket that insulates each individual insulated conductor, making them less vulnerable to shearing or penetration damage.
Another distinction between MC and Romex cables is that MC cables can be installed indoors and outdoors; however, the NEC states that MC cables should not be exposed to damp environments.
AC Vs MC Cable-What is type AC cable used for?
Cables are widely used in electrical applications. At their core, they all provide a path for alternating current of electric energy to flow. AC power cords, for instance, carry either 230V or 120V AC from an electrical supply directly into an appliance or piece of equipment.
AC power cords typically consist of a live wire that supplies current to an appliance, and an earth wire returning it to a busbar or ground-connected distribution box. This enables electricity to circulate throughout both the appliance and building’s electrical system, enabling it to function optimally.
When designing a cord for an application, the composition of its conductor and insulation will differ. Operating voltage, current-carrying capacity and environmental conditions all factor into the design of the cord.
The NEC Chapter Three describes various wiring methods, such as armored cable (Type AC), metal-clad cable (Type MC), nonmetallic-sheathed cable (Types NM and NMC), power and control tray cable (Type TC), and service entrance cable (Type SE). All these cable types have specific definitions within the Code so it’s essential to be familiar with what each means.
Can MC cable be used in residential?
Romex cable can be run indoors in some circumstances without the need for a conduit, however it does not provide the same level of protection as MC cable. Furthermore, Romex is susceptible to damage from pests, heat and moisture – so never use it outdoors or for industrial or commercial applications.
MC cables, on the other hand, feature built-in protection so they can be used indoors or outdoors without needing a conduit. Not only that but they’re often more economical than running wire through conduit and can save valuable labor hours as well.
When working with MC cable, it is essential to cut it gently in order to protect the armor on the conductors. For this task, an armored cable rotary cutter with a small cutting wheel powered by hand crank is ideal. Additionally, plastic anti-short bushings can be utilized as inexpensive ways of providing extra protection before being clamped into a connector.
What does AC cable stand for?
AC, also known as alternating current, is an electrical wave that flows in one direction periodically. It creates a sineoidal pattern with its produced electric waves.
AC power is much easier to transport over long distances than DC without losing much energy, and it is more reliable and less prone to breakdown or malfunctioning than its DC counterpart.
AC cables are composed of copper conductors encased in cord covers and insulation. Furthermore, these cables feature an outer rubber or polymer jacket to provide extra protection.
Furthermore, the cord’s rated voltage is important as it determines its insulation thickness and current-carrying capacity. Furthermore, this determines which outer cable jacket type should be utilized.
Another essential feature of an AC cable is its ground wire. This wire connects the cord to ground, helping protect you from electrical shocks.
Where is MC cable not allowed?
Metal-clad (MC) cable is the backbone of electrical industry. Not only is this type of cable safe and efficient, but it can save you both time and money in the process.
MC cables are popular due to their flexibility; they can be buried underground or above ground without the need for a conduit, making installation much simpler. Furthermore, MC cables boast greater strength and versatility and can be used in an array of applications.
One of the most prevalent applications for MC cable is in commercial and apartment buildings. Not only does it look good, but it meets code requirements while saving money in the long run as well.
Romex cable, unlike MC cable which is banned for fire-resistive and non-combustible constructions, can safely be used in all buildings. Unfortunately, it’s not recommended for tall buildings due to a few safety concerns; most importantly that it could pose a hazard at height – something you definitely do not want!
Is MC cable acceptable for exterior use?
MC cables are metal-clad cables used for electrical installations. Builders often opt for these due to their speedy installation and lower material costs compared to conduit wiring options.
MC cable is usually factory assembled and composed of one or more insulated circuit conductors enclosed in either an armor of interlocking metal tape, a smooth metallic sheath, or both. It’s commonly used for commercial, industrial, and multi-residential construction projects.
Electrical wiring with this option is ideal for locations requiring extra protection from fire, vibration, pests and physical damage. Not only that but it has excellent moisture-proof properties as well – meaning it can be buried directly into the earth or concrete.
MC cables are commonly installed for service, feeder, and branch circuits in buildings and other structures. It can also be utilized in a variety of applications like parking deck and lot circuits, swimming pool motors, as well as other industrial needs.
Where should type AC cable not be used?
Most homes have at least one AC circuit, and chances are you’ve used it most of the time. Unfortunately, AC wiring is highly susceptible to electrical failure, so it’s essential that you take safety measures like installing a properly labeled surge protector at source of supply line and an overcurrent protection device on all branch circuits. NEC even created an online safety checklist for electricians and others involved with residential wiring installation or maintenance – plus check out their website for a comprehensive list of local codes and ordinances applicable in your area.
