What is BX Wiring?

BX wiring, a type of armored cable wiring, first appeared in the 20th century as a way to meet the demand for durability, especially in industrial settings. BX wires contain one or more insulated hot conductors, one insulated neutral conductor, and a ground wire. They’re all wrapped in a somewhat flexible metal spiral made from either galvanized steel or a flexible metal. BX wiring is sometimes called armor clad, metal clad, MC wiring, metal and cloth wiring or flexible metal conduit cable.

Common Uses of BX Wiring

In their introduction, BX wiring was a popular choice in commercial and industrial settings for its durability, fire resistance, and robust grounding capabilities. Eventually, they were also adopted into homes. BX wiring is often used in construction projects, remodels, and renovations to reduce exposure to electrical fields. They can also be installed indoors or outdoors and can protect cables from vermin and foot traffic.2

Differences Between BX Wiring and Modern Wiring

Unlike BX electrical wiring, modern wiring is flexible and easy to work with. The metal surrounding BX wiring is hard to deal with. Meanwhile, modifying modern wires is straightforward during a renovation project. They are also more lightweight than BX wiring, making them easier to handle and install.

Signs You May Have BX Wiring in Newton

If you’re not sure if you have BX wiring in your home or not, there are some signs to watch out for.

Metal Cables in Your Walls or Attic: Look for metal-sheathed cables running through your walls or attic that are usually silver or gray. They also have a very distinctive appearance, like flexible armor.
Your Home Was Built or Renovated Before the 1960s: It’s more likely to have BX wiring in an older home. If your house was built or renovated before the 1960s, there’s a high probability you have BX wiring to meet the safety standards of that time.
Connector Types: BX wiring often relies on specialized metal connectors or clamps to attach the armored cable to electrical boxes. The connectors are highly durable and robust and they use screws or clamps to keep the sheath from being pulled out of the box.

Common Issues with BX Wiring in Newton

BX wiring may look like a sturdy, protected option, but older BX systems in Newton, MA often come with hidden risks. As the insulation inside the metal armor ages, it can dry out, crack, or crumble, raising the chance of shorts, overheating, and even electrical fires. In damp or corrosive areas, the metal sheath itself can deteriorate, leading to grounding problems or electrical failures. On top of that, BX is hard to modify, and many older installations weren’t designed for today’s electrical loads or current code requirements.

Common issues with BX cable wiring include:

Aging or brittle insulation that increases the risk of shorts and overheating
Cracked or deteriorated sheathing that can expose conductors
Grounding problems caused by corrosion or failure in the metal armor
Damage or decay in damp, wet, or corrosive areas (basements, crawl spaces, etc.)
Difficulty making repairs or upgrades due to the rigid metal jacket
Circuits that can’t safely handle modern electrical loads, leading to frequent overloading
Older installations that may no longer meet current electrical codes and safety standards

Should You Replace BX Wiring in Newton?

Deciding whether to replace BX wiring requires an inspection and thorough assessment of its conditions. Even if it’s in good condition, you still need to understand the pros and cons of keeping or replacing it.

If you’re considering replacing your BX wiring in Newton, MA, here are some pros to consider:

Improved Safety:

BX wiring, especially in older homes and installation projects, may lack the ability to ground after years of deterioration and pose electrical hazards.

Code Compliance:

Updating your BX wiring to modern electrical codes makes sure you stay compliant with the latest safety standards and regulations.

Increased Reliability:

Newer electrical wiring is less likely to have shorts and degraded insulation.

Potential Energy Savings:

Upgrading your home with newer electrical wiring may support more energy-efficient fixtures and modern appliances.

Enhanced Property Value:

Expanding and upgrading your electrical system can add to the long-term value of a property.

Improved Performance:

Newer wiring can handle higher electrical loads and may provide more stable power delivery.

Long-Term Cost Savings:

Over time, upgrading your home’s wiring can reduce your maintenance costs and potentially lower your insurance premiums.

Modern Features:

Updated wiring allows for the installation of modern technology and smart home devices.

Compliance with Insurance Requirements:

Your insurance policy may require that you update your electrical system with BX wiring to remain compliant and secure coverage eligibility.

Peace of Mind:

When there’s a reduced risk of electrical fires or hazards, you enjoy more peace of mind knowing that your home is safe

Options for Replacing BX Electrical Wiring in Newton

One option for replacing your BX wiring is to upgrade to NM-B (non-metallic sheathed) cable. It’s easier to work with and meets the current electrical codes and best standards.

Unlike BX wiring in Newton, NM-B cables mostly consist of insulated copper wires that are housed in a flexible plastic sheathing.

Another alternative is EMT, or electrical metallic tubing. It provides the robust protection you need and allows more flexibility for modifying your electrical needs in the future due to its metal conduit.

Newton BX Wiring FAQ

What is BX wiring, and why is it a problem?

BX wiring is an older type of electrical cable protected by a flexible metal sheath. While durable for its time, the insulation inside often becomes brittle or cracked with age. In many Newton homes, this deterioration increases the risk of electrical shorts, overheating, and potential fire hazards. BX wiring can also corrode in damp areas, making it unsafe and unreliable by modern standards.

How do I know if my Newton home has BX wiring?

BX wiring is commonly found in homes built before the 1950s, though it sometimes remained in use later. Signs you may have BX include a flexible, spiraled metal casing around wiring in your basement, attic, or electrical panel. The safest way to confirm is to schedule an inspection with Castle Electric, as BX is often hidden behind walls and ceilings.

Is BX wiring still allowed under Massachusetts electrical code?

In many cases, older BX wiring does not meet current electrical code requirements in Massachusetts, especially when insulation has deteriorated or grounding is compromised. While having BX doesn’t automatically make a home unsafe, damaged or outdated BX typically must be removed or replaced during upgrades, renovations, or when safety issues are found.

What are the risks of keeping BX wiring?

Aging BX wiring can lead to shorts, unreliable grounding, overloaded circuits, and increased fire risk. The metal sheath can corrode in damp basements or crawlspaces—something common in older Newton homes—leading to further hazards. Many modern electrical demands (HVAC, appliances, EV chargers, etc.) also exceed what old BX circuits were designed to handle.

How is BX wiring removed or replaced?

Castle Electric begins with a full evaluation of your electrical system to determine the extent of BX wiring in your home. We then safely disconnect and remove outdated sections and replace them with modern, code-compliant wiring (typically NM cable or MC cable). We also inspect grounding, connections, and panel capacity to ensure everything functions safely and efficiently.

Will removing BX wiring damage my walls or ceilings?

Some access is often required, but Castle Electric uses minimally invasive techniques whenever possible. In many Newton homes, BX removal can be done with limited openings, and we always discuss the scope of work before starting. We also coordinate with homeowners or contractors if patching or finishing is needed afterward.

How long does BX wiring replacement take?

The timeframe depends on how much BX wiring is present and how accessible it is. Smaller upgrades may take a few hours; whole-home replacement can take several days. During your inspection, Castle Electric provides a clear timeline so you know exactly what to expect.

Is BX wiring removal expensive?

Cost varies widely based on the scope of the project, but Castle Electric offers clear, upfront pricing and will walk you through every option. Replacing old BX wiring is an investment in safety, reliability, and long-term peace of mind—and often increases the value of older Newton homes.

Do I need to replace all BX wiring at once?

Not always. Castle Electric can help you prioritize the most urgent areas first—such as damaged sections, improperly grounded circuits, or areas with high moisture. We can also plan phased upgrades that fit your budget and renovation schedule.

Will upgrading from BX improve my electrical system’s performance?

Yes. Replacing BX wiring typically improves safety, grounding reliability, system capacity, and overall consistency. Modern wiring better supports today’s electrical loads, reduces nuisance tripping, and ensures your home is ready for future upgrades like heat pumps, EV chargers, or generator integration.

“Our 99 year old father had a complete power failure. Castle came out immediately and within two days replaced every wire and put in a new electrical panel in a new location. It was amazing that they were out to his house immediately and replacement was done without a hitch. The wiring inspector commented on what a great job they did. It was a huge job and it was a really difficult situation as my father would not leave the house. We are so grateful to Castle. Not considering the quality of work alone, they were kind and considerate of a very old man. Thank you Castle Electric and we highly recommend your services.”
