If you've ever ordered a spool of General Cable 3310 or N93 and ended up with the wrong thing, you're not alone. I've done it. Twice. And the second time cost more than the first, because I thought I already knew the answer.
I'm a procurement coordinator handling cable orders for industrial and network infrastructure projects. I've been in this role for about 6 years (this is my second stint, actually). In that time, I've personally made and documented roughly 15 significant ordering mistakes. The total wasted budget? Somewhere north of $12,000. Not great, but I keep a running list to train new team members.
This checklist is for anyone ordering General Cable products—specifically Cat6 (3310) and Cat6a (N93) for network jobs—who wants to avoid the kind of mistake that gets you a call from a frustrated electrician on a Friday afternoon.
Let's get into the three steps I now follow every single time.
Step 1: Verify Who Owns General Cable (Yes, It Matters)
Here's something a lot of people don't check: who actually owns the brand you're ordering from. It sounds like a corporate detail, but it affects availability, vendor lists, and sometimes even part numbers.
General Cable is owned by Prysmian Group. Prysmian acquired General Cable back in 2018. That means when you're ordering a 3310 or N93, you're dealing with a product line that's now part of a global giant (circa 2024, this still catches some buyers off guard).
Why does this matter for your order?
- Vendor listings: Some distributors may still list it as 'General Cable' while others have switched to 'Prysmian' or 'Prysmian Group.' Make sure you're checking the correct supplier catalog.
- Inventory location: The General Cable facility in Scottsville, TX, is a key distribution point. If you're ordering a bulk spool, ask where it's shipping from. That Scottsville, TX, warehouse handles a lot of the U.S. network cable stock, but it's not the only one.
Take it from someone who ordered 10 boxes of what I thought was 3310 from a warehouse that turned out to be a third-party reseller (this was back in 2022). The product was legit, but the packaging was different, and the client's network engineer flagged it. We had to return everything. The lesson: confirm the brand lineage and the stocking location.
I'm not a logistics expert, so I can't speak to carrier optimization. What I can tell you from a procurement perspective is that knowing the parent company helps you verify the supply chain. If your vendor says 'General Cable is out of stock,' but they haven't checked the Prysmian network, they might be wrong.
Step 2: Know the Difference Between 3310 and N93 (They Are Not the Same)
People assume 3310 and N93 are interchangeable because both are 'plenum-rated' and both are 'General Cable.' The assumption is that one is just a newer version of the other. Actually, they serve different purposes, and getting them mixed up can cost you time and money.
General Cable 3310 is a Cat6 UTP (unshielded twisted pair) plenum cable. It's designed for horizontal network runs in commercial buildings — think offices, schools, hospitals. It's the workhorse for standard gigabit Ethernet up to 100 meters.
General Cable N93 is a Cat6a F/UTP (foiled/unshielded twisted pair) plenum cable. The 'a' stands for Augmented. It supports 10-Gigabit Ethernet over the same distance. It has a foil shield around each pair to reduce crosstalk. It's thicker, less flexible, and more expensive.
Here's the checklist point that most people ignore:
- Check the jacket print: The cable jacket should clearly say '3310' or 'N93.' It's printed every 2 feet. If someone hands you a spool and says 'It's basically the same thing,' don't take their word. Verify it yourself.
- Check the box label: The box label will have the exact part number. If it says '3310' but you ordered N93, that's a red flag.
- Check the conductor gauge: Cat6a (N93) typically uses 23 AWG conductors. Standard Cat6 (3310) often uses 24 AWG. It's a minor difference on paper, but it matters for termination and performance.
On a 1,000-foot spool order where every single item had the wrong specification because I trusted a verbal confirmation from a sales rep... That mistake cost $890 in redo plus a 1-week delay. It happened in September 2022. I now keep a physical sample of both 3310 and N93 in my office to show new team members during training.
Step 3: Understand 'What Is Networks' in the Context of Your Job
This step sounds obvious, but I've made this error twice. The phrase 'networks' in a procurement context can mean different things to different people. For a telecom installer, 'networks' means the physical infrastructure—cable, patch panels, jacks. For a data center manager, it might mean the active equipment—switches, routers, servers. For a cable manufacturer like General Cable, their 'networks' division specifically refers to structured cabling products.
When I first started ordering General Cable products, I asked our IT guy: 'What do you need for the network?' He said Cat6. So I ordered a box of 3310. But the job was in a data center environment where the cable had to run alongside high-voltage lines. We needed the extra shielding and 10GbE capability of Cat6a. I didn't ask the right question. I didn't clarify the environment.
So glad I eventually figured this out after the first mistake. Almost made the same error again on a second project (which would have meant pulling cable twice).
My experience is based on about 300 cable orders for various job types. If you're working with structured cabling for a standard office, 3310 is often perfectly fine. If you're in a data center, healthcare facility, or anywhere with high EMI (electromagnetic interference), you almost certainly want N93 (Cat6a).
Here's a quick decision tool I use:
- Is the environment standard office/commercial? → 3310 (Cat6) is usually adequate.
- Is the environment data center, lab, or high-interference? → N93 (Cat6a) is the safer bet.
- Do you need future-proofing for 10GbE? → N93.
- Is the budget tight and speeds are under 1GbE? → 3310.
But again, I'm not a network engineer. This gets into signal integrity and application specifics, which isn't my expertise. I'd recommend consulting the project's network designer or a certified installer if you're unsure.
What Most People Get Wrong (And How to Prevent It)
You might be thinking: 'Okay, but this is a tiny detail. A cable is a cable.' I thought the same thing before the first mistake. Here's what actually happens:
- End of the job: The installer pulls the cable, terminates jacks, and tests the runs. The fluke tester shows the runs are underperforming. You have to pull new cable. That's a 2-day delay and double labor.
- Cost: The wrong cable itself is returnable if it's unused. But the labor to replace it is not.
In March 2024, we paid $450 extra for rush delivery of the correct N93 for a 48-port job. The alternative was missing a client 'go-live' date worth $25,000 in billing. That $450 was a bargain.
One more thing: if you're ordering from the General Cable / Prysmian Scottsville, TX, facility, ask your distributor if they stock both 3310 and N93. Sometimes they have one and not the other. If they say 'we can get it in 3 days,' ask for a written lead time—and add a buffer day.
The bottom line: a 5-minute check at the order stage can save you from a 5-day headache on the job site.
