AC Cable Buyers in Pennsylvania
Armored cable from Pennsylvania contractors and plant maintenance stores, reviewed by buyers who read the bonding strip.
AC cable is the interlocked armored product that electricians still call BX. Two or more insulated conductors sit inside a flexible steel or aluminum armor, and a thin aluminum bonding strip runs the length of the armor in intimate contact with it. That strip is what makes the armor a legal ground path, and it is the detail that separates AC from metal-clad cable. The armor also protects the conductors from physical damage in a way that a jacketed cable cannot match.
Most AC we review comes from remodel work in older Pennsylvania buildings, where the existing wiring is armored and a contractor matches it rather than converting to MC. Health care work supplies another steady stream, because the hospital version of AC carries a green grounding conductor and is required in patient care areas. Shop cleanouts add coils of 14/2 that have sat on a shelf for years and are still perfectly usable. A coil of 12/2 that never left the truck is the most common single item we see from that trade.
| Construction | Interlocked steel or aluminum armor with an internal aluminum bonding strip in contact with the armor |
|---|---|
| Conductors | Stranded copper, usually 14 AWG through 10 AWG, in two to four circuit conductors |
| Ground path | The armor and bonding strip serve as the equipment ground; standard Type AC has no green conductor |
| Voltage and temperature | 600 V; conductors commonly rated 90 C dry |
| Standards | UL 4 and NEC Article 320; Type HCF is the health care variant with an insulated green ground |
What AC cable is
Type AC is a factory assembly of insulated conductors inside a flexible metal armor, with the bonding strip folded in as the armor is formed. The strip creates a low impedance path so the armor can carry fault current and clear a breaker. Without it, the armor alone is a poor conductor at the joints and the cable would not be acceptable as an equipment ground.
Conductors are normally THHN or THWN singles, and the assembly is rated 600 V. Type HCF is the same idea built for health care facilities, with a full-size insulated green grounding conductor added so the installation satisfies the redundant ground requirement in patient care areas.
- Standard AC has no green wire and grounds through the armor
- HCF adds an insulated green conductor for hospital work
- Armor is steel in most legacy installations and aluminum in lighter commercial versions
Where Pennsylvania sellers use AC cable
Older cities and boroughs are the natural home of this product. Renovations in Philadelphia rowhouses, Pittsburgh commercial buildings, Scranton and Erie frequently open a wall and find armored cable, so the replacement work is specified in kind. A contractor who keeps a coil on the truck often has two or three partial coils left at the end of a season.
Hospital and clinic projects account for the HCF volume, since patient care areas require the redundant ground. Plant maintenance departments also keep AC on hand for repairs in older electrical rooms where the existing branch circuits are armored and matching the original method is simpler than fishing conduit.
What makes AC cable resellable
The market for AC is narrower than for MC but deeper than most sellers expect, because the buildings that need it are still standing and still being renovated. Standard 12/2 and 14/2 coils in full 250 ft lengths are the easiest to place. Three conductor and 10 AWG versions are bought by contractors doing feeder and subpanel work in older structures.
HCF cable carries a premium when the print is clear, since it cannot be substituted with ordinary AC on a health care job. Coils still in factory cartons with the original label are the strongest, followed by clean coils with a readable tag. Loose armored cutoffs have little resale life and are usually evaluated on copper content.

- Full 250 ft coils of 12/2 and 14/2
- HCF print legible on the armor
- Clean armor without heavy rust
Condition, storage and identification
The armor is the vulnerable part. Steel armor rusts when a coil sits on a damp concrete floor, and rust at the interlock eventually weakens the ground path. Aluminum armor does not rust but dents and crushes, and a crushed interlock is difficult to pull without damaging the conductors inside. Coils stored on a shelf in a dry shop are usually in better shape than coils that rode in a truck bed for a year.
Identification is printed on the conductors and sometimes on the armor tape. A cut end showing the bonding strip and the absence of a green conductor is the clearest signal that the material is AC and not MC. Reel tags and carton labels help, and the wire gauge is often stamped on the carton end.
What to send for a quote
Photograph the coil or carton label, the cut end and the armor. Note the sizes and how many coils of each, and whether the material is standard AC or HCF. If the label is gone, a photo of the conductors with a ruler across them is enough for us to identify the gauge.
We review the inventory and send a quote, then arrange pickup if it is accepted. Coils are light enough to handle by hand, so access is rarely a problem, but tell us if the material is on an upper floor or behind a locked gate so the pickup can be planned.

AC Cable questions
Is BX the same thing as AC cable?
BX is the trade name electricians use for armored cable. The listed product is Type AC, defined by UL 4 and NEC Article 320, and it grounds through the armor plus the internal bonding strip.
Do you buy AC cable without a green ground wire?
Yes. Standard AC has no green conductor by design, so its absence is normal rather than a defect. We check for the bonding strip instead, which confirms the armor is listed as a ground path and that the cable can still be installed.
What is HCF cable worth compared with standard AC?
HCF usually prices higher per foot because it satisfies health care grounding requirements and cannot be replaced with standard AC. Value depends on legible print, coil condition and the sizes a hospital contractor needs, with 12/2 moving faster than 14/2.
Will you take short armored cutoffs?
Short pieces are reviewed, but they rarely have resale value as cable. We tell you honestly when a lot is better treated as copper recovery than as usable stock, and we will still quote it either way.
