What else can I help you with?
What was used before romex wire became available?
Before Romex wire became available, cloth-covered wire, knob-and-tube wiring, and armored cable (BX) were commonly used for electrical wiring in residential buildings.
Was silver ever used in bx wire?
No, silver was never used in BX cable.
Is the outer sheath on BX cable an adequate ground path?
It used to be, but now the ground wire (which replaced the aluminum strip) in the BX cable is used. The ground wire is now used to complete the grounding of connected devices rather that the sheath of the BX.
What is a BX connector?
A BX connector is a special type of box connector used for securing a BX cable to a junction box. BX is a type of armoured cable that is used for specific locations where ordinary Romex cable could become damaged. Before the connector is installed onto the BX cable there is a small PVC collar to be installed. In the trade it is called an anti short. It slides between the outer sheath of the BX and the conductors inside the sheath. It adds protection for the inner conductors from rubbing against the outer sheath if any vibration is involved in the installation. There is usually a small hole in the BX connector and the red anti short can be seen through this hole. This makes it easy for the electrical inspector to see if the anti short bushing has been installed during an inspection, and they do check.
My new table saw has a cord with three wires total red black and green can you run two wire BX from the breaker panel and if so do you just consider the black and white as hot and no neutral?
Sounds as though your saw is a 220 volt saw. If so then yes if you run a 2 conductor BX cable you will employ the black and white conductors in the cable as the two "hot" conductors. So just wire black to black, and red to white. However, you should be running a 3 conductor cable to provide a ground to your saw.

No, silver was never used in BX cable.
Can you mix bx and romex in a CB panel?
Yes, you can mix BX (flexible metal conduit) and Romex (non-metallic sheathed cable) in a circuit breaker (CB) panel, as long as the wiring methods comply with local electrical codes and the panel is properly configured for the different types of wiring. However, it's important to ensure that the connections are secure and that the appropriate fittings and connectors are used to maintain safety and code compliance. Always consult local regulations or a licensed electrician when in doubt.

What is the BX wire function?
The BX wire function refers to the use of BX (or armored) cable in electrical installations. BX cable is characterized by its flexible metal conduit that provides both protection and grounding for the insulated conductors inside. This type of wiring is often used in residential and commercial applications due to its durability and resistance to physical damage. It is particularly beneficial in environments where exposure to moisture or mechanical stress is a concern.
What are the common uses of BX wire in electrical installations?
BX wire, also known as armored cable, is commonly used in electrical installations for its durability and protection against physical damage. It is often used in residential and commercial settings for wiring that requires extra protection, such as in exposed areas or where there is a risk of damage from rodents or other hazards.
When armored cable is used what protection is provided at the cable end?
these little devices are generally called connectors when you cut the armor it leaves some burs so there a little fiber bushing you slip under the armor and over the wire before putting in into the connector and into the box rome cable company had a armored cable they called BX which kinda stuck the generic term is MC for metal clad MC Cable Connectors <<>> These little red bushings that come with rolls of BX cable are called anti-shorts. <<>> the little bushings are also called redheads
What kind of wiring would be encased in a corrugated metal tubing under an electric cook top We want to rip it and cupboards out below and put in a freestanding electric oven?
This is BX cable also considered AC cable. It is sheathed in either aluminum or steel sheath. It was used years ago to wire most homes but has been replaced by Romex. Here's a great blurb that I found. . http://www.faqs.org/faqs/electrical-wiring/part2/section-5.html

How do you glue bx cable to steel beam?
You don't glue BX cable to steel. If it has to go on a beam, you usually hold it on with plastic 'tie wraps'. --------------------------------------------------------------------- Wire ties are not recommended for mounting armored bx cables to steel beams. Wire ties are normally used for bundling wires together to keep them neat, though some glue on cabinet tabs are made to mount wires inside control cabinets. These are not meant for external wire mounting. Cast aluminum clamps are made that hold the bx cable to the beam. a hole must be drilled in the beam to mount the clamps with screws, OR specially made mounting clamps (similar to c-clamps can be mounted to the edge of the beam, then the clamps mounted to those. It is recommended there be no less than one clamp every 6 feet (~2 meters).
What does bx stand for in bx cable?
