Hubbell Purchasing: What I Learned About Cat 6 Jacks, Voltage Drop, and the 2660 Flip After 5 Years

This isn't a product pitch — it's a map of the traps I've stepped in

When I took over purchasing for our company in 2020, I thought buying Hubbell products was straightforward. You pick a model, check the price, and order. Five years and about 400 orders later (give or take — I'd have to check the exact count), I've learned there's no single "best" Hubbell jack, connector, or switch. It depends entirely on what you're wiring and who's paying the invoice.

Let me walk you through three common scenarios I've faced. One of them will probably match your situation. If it doesn't, skip to the end where I explain how to figure out which bucket you're in.

Scenario A: The Big Build-Out (New Data Center / Major Renovation)

What's at stake: Scale, consistency, and voltage drop

We expanded our data center in 2022. Roughly 400 new drops, and the contractor wanted to use a cheaper non-Hubbell Cat 6 jack. I've managed orders for 400 employees across 3 locations before, so I smelled trouble. The question was about voltage drop over long runs in the ceiling. The contractor said: "It's fine." I said: "Let's check."

What I learned: Voltage drop isn't a joke, especially for PoE+ devices (like cameras and access points at the end of long cable runs). The IEEE 802.3bt standard specifies a maximum voltage drop, and the math is boring until your security camera reboots every 15 minutes because it's getting 42V instead of 48V. We used Hubbell HBL1221 style connectors throughout because they maintain signal integrity better over distance. Was it the cheapest option? No. But the cost of re-cabling one failed run is higher than the upcharge for quality connectors.

My recommendation for this scenario: If you're building new infrastructure at scale, don't cheap out on the jacks or patch panels. Stick with Hubbell Cat 6 jacks — specifically the ones rated for 10GBASE-T. The HBL1221 is a solid choice for power distribution in the same racks. The cost of future troubleshooting far exceeds the savings from a generic jack. (Ugh, I learned this the hard way in 2021 — we had to re-terminate an entire floor because the cheap jacks failed certification. That invoice still haunts me.)

Scenario B: The Everyday Office Floor (Standard Fit-Out, Routine Maintenance)

The question: Bronze vs. silver contacts — does it matter?

For your standard office — think cubicles, conference rooms, and break rooms — the debate often comes down to bronze vs silver contacts for wiring devices. One vendor told me: "Silver is always better." I've heard that line. Let me rephrase that: vendors say a lot of things when they're trying to upsell.

What I found: In a typical office environment with standard loads (computers, monitors, a mini-fridge), bronze contacts are perfectly adequate. They have good conductivity, excellent durability, and lower cost. Silver contacts are better for high-cycle applications — think hospital beds that get unplugged every hour or manufacturing lines where equipment is swapped regularly. For the meeting room where the projector gets used twice a week? Bronze. Save the budget.

About the 2660 flip: I've seen the 2660 flip style connectors recommended for some applications. Honestly? They're great for quick terminations in tight spaces (like back of a cubicle partition). But if you have room for a standard connector, go with that. The flip mechanism (fortunately) saves time, but it's slightly bulkier.

What I'd do now: For an office re-fit, use Hubbell HBL1221 for the power side — it's a workhorse. On the data side, standard Hubbell Cat 6 jacks with bronze contacts. No need for silver unless you're expecting daily plug/unplug cycles (like a training room). Simple. Done.

Scenario C: The Budget-Sensitive Project (Small Office, Temporary Space, or Add-On Work)

Where I eat my own words: Sometimes cheaper works (if you're careful)

Here's the part that might surprise you. I have approved non-Hubbell jacks on one project — a temporary breakroom expansion we needed for 90 days during a renovation. The contractor brought generic Cat 6 jacks for $2.50 each vs. $6.50 for Hubbell. I hesitated. With a 2-hour deadline to approve the order (the CEO needed the room ready in a week), I let it slide.

Result: They worked fine for three months. No failures, no re-cables. The network admin ran a test — speed tests were within 5% of the Hubbell jacks in the permanent offices. Why does this matter? Because sometimes the “better” option is overkill for non-critical, short-term use.

But — and this is a big but — if we'd needed those jacks to last 5 years, I'd have paid the premium. I've seen bronze contacts corrode in humid environments (like our warehouse in Florida, circa 2023). I've seen voltage drop cause flickering lights in a temporary setup that “was only going to be used for a month” — which turned into 8 months.

What I recommend for this scenario: If it's truly temporary (under 6 months) and not critical infrastructure (no servers, no medical equipment), you can use lower-cost alternatives. Just don't tell my VP I said that. Document the expected life and get sign-off. I dodged a bullet when that breakroom expansion only lasted 4 months — if it had been permanent, I would have looked bad. So glad I pushed back on the timeline originally (in hindsight, lesson learned).

How to Tell Which Scenario You're In

It's easy to get lost in product specs. Here's my cheat sheet:

• You're in Scenario A if you're wiring a new building, data center, or any space that needs to pass certification. Also if the wiring is expected to last 10+ years. Invest in Hubbell Cat 6 jacks (rated for 10GBASE-T) and HBL1221 power connectors. Consider voltage drop calculations for long runs.
• You're in Scenario B if this is a standard office fit-out, routine maintenance, or any space where daily abuse isn't likely. Use Hubbell HBL1221 for power. Bronze contacts are fine for most office loads. Only spec silver contacts if you have high-cycle equipment. The 2660 flip is optional — good for speed, but not a must-have.
• You're in Scenario C if it's temporary (under 6 months), non-critical, or if the budget is truly constrained. You can save money on jacks — but promise yourself you'll upgrade if it becomes permanent. Document the decision. (I've seen a “temporary” setup become permanent 3 times. Once, I could have saved the cost of re-cabling with a better initial spec.)

The magic of the scenario branch is that it acknowledges infrastructure choices aren't universal. What works for a data center fails for a breakroom. What works for a breakroom fails for a hospital. Knowing which scenario you're in is more than half the battle.

Why This Matters (And What I'd Change If I Could Start Over)

I wish someone had told me in 2020: "Don't just pick a product. Pick the scenario first." The biggest mistakes I've made weren't from choosing the wrong brand — they were from choosing the right brand for the wrong application.

Hubbell makes excellent products. Their Cat 6 jacks are certified for 10GBASE-T. The HBL1221 is a reliable power connector. But even a good product can be a bad choice if it's over-specified (wasting money) or under-specified (creating reliability issues).

One last thing: always, always check your voltage drop calculations for PoE runs. I didn't on my first big project, and we had to re-cable 12 runs — each one cost more than the connector itself. Per industry standard, voltage drop should stay under 5V for PoE+ (per IEEE 802.3bt). Our runs at 90 meters were hitting a 6.5V drop with generic connectors. Switching to Hubbell HBL1221 and certified Cat 6 jacks brought it to 4.2V. That's the difference between a working camera and an expensive paperweight. (Source: ANSI/TIA-568.2-D guidelines on PoE cabling, which I now keep bookmarked.)

In short: match the gear to the scenario, document the decision, and don't let a contractor convince you that cheaper is always acceptable — or that premium is always necessary. The truth is somewhere in the middle, and that's where good purchasing lives. Period.

Quick Reference: Key Terms & Recommendations

(As of Q1 2025, at least — product lines change, so always verify current specs. I'm basing this on what I've ordered and seen work for the past 5 years.)

P.S. A Note on the “2660 Flip”

I get asked about the 2660 flip style connector a lot. It's a right-angle adapter for tight spaces (think back of a desk or a wall plate). Helpful? Yes. Essential? No. For 90% of office installs, a standard straight connector is fine. The flip is a convenience, not a necessity. If your contractor recommends it for every drop, ask why. (Unfortunately, some just want to bill the extra part.)

The one place I'd always use it: If you're installing behind a TV mount or in a shallow gang box where a standard plug would stress the cable. Otherwise, skip it.
