When I took over office purchasing in 2022, I treated cable like paper reams. If every quote said “Prysmian power cable,” I picked the cheapest one and moved on. My attitude was: the brand was already specified. How wrong could the order go?
Answer: very wrong, during a VoIP phone upgrade that was supposed to be simple.
The order that made me stop guessing
We were replacing an old PBX with VoIP desk phones for about 120 people on three floors. The IT manager asked for new power feeders to the telecom room. On my desk, that request turned into an RFQ for Prysmian power cable. I got three quotes.
One came in around 30% lower than the other two. In my mind, that was a no-brainer. Same brand, same type of cable, lower price. I approved it.
The boxes arrived with Carol by Prysmian labels. I did not blink. In procurement, that looked like the same corporate family. Then the electrician called.
“This is flexible cord,” he told me. “It’s fine for portable equipment. I can’t install it as permanent wiring in a telecom room.”
It was at that moment I realized the phrase “Prysmian power cable” had done all the work on my purchase order—and it was not enough.
The real culprit: I ordered a category, not a product
The problem was not the supplier. It was not even the Carol by Prysmian brand. The problem was that I was buying a broad category instead of one specific product.
If I had looked at the actual product page, I would have seen the rating, the jacket type, and the intended installation method. Instead, I compared prices for a generic description and let the vendor decide what “power cable” meant. That is how a careful buyer accidentally orders the wrong thing.
Here is the uncomfortable part for people like me who manage office purchasing: brand names can feel like specifications. But a brand name only tells you who made it. It does not tell you whether that product is rated for in-wall use, riser spaces, plenum spaces, direct burial, or a few hundred feet of permanent feeder cable.
If you have ever bought cable for office phones, you know what I mean. You think you are buying a simple power or data cable. In reality, you are buying a compliance decision, an installation outcome, and a maintenance headache if the choice is wrong.
The cheapest quote cost more than the price difference
The low cable quote saved us about $170. The correction cost us a lot more.
- We paid for the electrician to re-pull the run.
- We paid for the replacement Prysmian power cable with the correct rating.
- We paid for a second site visit because the phone vendor could not finish their work on the original schedule.
- I spent two days rescheduling internal teams, plus one awkward meeting explaining the delay.
The total was somewhere around $2,000. And that number does not include the trust I lost with the IT manager. He did not care that the cable came from a reputable manufacturer. He cared that the wrong product was sitting in his telecom room.
Honestly, the worst part was the message it sent. If I can make a $170 mistake on something as boring as cable, people start to wonder about the bigger purchases. That is the hidden cost nobody puts on an invoice.
Price only matters after the product page exists
Now my rule is simple: no product page, no purchase order. I never approve a cable request based on a category name alone.
If I need a fixed building feeder, I look for the exact Prysmian power cable product page and copy the manufacturer part number into my quote request. If I need a flexible cord, I compare specifications on Prysmian Carol Cable product pages. And when someone gives me a legacy item number like 2780, I do not guess from memory—I open the saved VSRX product page and check the current datasheet before I approve anything.
For phone-system work, the same rule applies. Desk phones, VoIP gateways, and network switches all depend on cabling that has to match the space where it runs. Ten minutes on the right product page at the beginning saves a lot more than ten minutes at the end.
I still negotiate on price. I still look for savings. But now I only compare quotes when they are for the same exact product. The cheapest quote can win—once it is quoting the right thing.
If you are the person in your company who actually places the cable orders, take this seriously: a brand name is not a spec. Find the product page first. Save the part number. Send that part number to every vendor. Your future self will thank you, and your electrician will definitely thank you.
