What does BX mean in electrical?
BX cable, a genericized trademark term for a type of AC armoured electrical cable (from ‘Bronx cable’) BeppoSAX catalog, also called SAX and 1SAX. Brix (°Bx), measurement unit of the dissolved sugar-to-water mass ratio of a liquid.
What is the difference between AC cable and MC cable?
The biggest difference between the two cable systems is that MC has full size ground wire while AC uses a combination of the jacket and a thin bonding strip or wire to function as the equipment ground. … Note: Early AC cable often does not have this bonding wire.
Can you run MC cable into a plastic box?
MC Cable is for metal boxes only! Plastic or fiberglass boxes aren’t designed to be used with MC cable. Even if you’re able to rig up a connection to a plastic box, you will fail the electrical inspection.

Properly installed surface metal raceway containing an insulated equipment-grounding conductor may be used to supply receptacles in patient care areas of a hospital as outlined in 517.13 (A) and (B).
Can you paint MC cable?
The quick answer is “yes,” but let’s cover some of what you’ll need to know first. Painting the armor does not violate the National Electric Code (NEC), however, this process can be time consuming and also create more cleanup on the job-site utilizing pre-painted armor saves time and labor.
Is BX cable legal?
BX is accepted by the National Electrical Code (NEC). Older BX cables without an internal bonding strip are not accepted by NEC. NM cable is also accepted by the NEC.
Where can MC cable be used?
A. Type MC cable can be used for service-entrance conductors, feeders and branch circuits in many applications. Section 330.10 of the National Electrical Code includes the general uses permitted for Type MC cable. Many other uses are permitted in other articles for specific applications.
Is Mc considered conduit?
Type MC is permitted for services, feeders and branch circuits, indoors or outdoors, exposed or concealed. It may be used in some, but not all classified locations. It is permitted in wet locations and underground where identified for such use. A conduit bender is the only specialized tool needed for working with EMT.
Is MC cable weatherproof?
Type AC cable is approved by the NEC for use only in dry locations. In order to comply with the NEC for use in wet locations, interlocked Type MC Cable must have a corrosion resistant jacket and wet location rated conductors. A common style cable that is rated for wet locations is a standard MC Cable with a PVC jacket.
Can you bury armored cable?
Armoured cables and cables having an earthed metal sheath suitable for use as a protective conductor may be buried directly in the ground without further protection, except against corrosion, which may be negated by the provision of a plastic covering.
What is the difference between BX and MC?
For those who are not familiar with the difference between the two, BX has a mechanical ground as part of the armored cable wall or jacket, where MC has an “extra” green wire that is used for grounding purposes. … Those are the only differences between the two cables.
How often do you strap MC cable?
According to NEC Article 330.30, MC cable must be supported and secured at intervals of 6 feet or less (unless routed through a framing member) and cables containing four or fewer conductors sized no larger than 10 AWG must be secured within 12 inches of every termination.
Is armored cable waterproof?
As others have said armoured cable, we have lots of it running fom the house down the garden to get power to a shed, greenhouse, workshop and exterior power point. It has the normal plastic coating and thus is waterproof.
Does MC cable required anti Short bushings?

Can you use MC cable in a garage?
Can MC cable (14-2) be used to wire a residential garage? Article 330 says it can be used as open runs of cable not subject to physical damage. Rather than fish wires through walls, the MC cable would be run exposed to supply electrical outlets. Also, there is no seperate ground wire, just the bonding wire.
Can MC cable be run exposed?
Type MC Cable without an outside nonmetallic jacket can be installed in an “other space used for environmental air” in accordance with Section 300.22(C). These cables can be installed either indoors or outdoors and in exposed and concealed locations. They can be direct buried, where identified for such use.
How many MC Can you bundle together?
There are roughly ten 12-2 MC cables installed in bundled configuration using nylon tie wraps. These cables are the homeruns for 20-ampere branch circuits. Appreciate your insight. Section 310.15(B)(3)(a)(5) says that if they exceeded 20 current carrying conductors the derating is 60%.
Is Pyro cable still used?
Mineral Insulated Cable (MICC) has been in use commercially since 1937, the fact that it is still widely used today is evidence that it has not been bettered by any other cable system. … MICC cables can also be considered to be non-aging as copper and MgO will not deteriorate with age in most situations.
