If you are wiring a garage subpanel, a shed, or a service entrance, the wire itself is the one part you cannot swap out later once it is buried. The three picks below are all genuine 2-2-4 aluminum cable, meaning the two main current-carrying conductors are 2 AWG and the neutral is 4 AWG. The first decision is conductor count: four insulated conductors plus a bare ground for a dedicated grounding bar, or a triplex run for a simple buried feed.
I’m Mohammad Maruf — the founder and writer behind KitchPrep. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
You will see ampacity ratings (how much current a wire can carry safely), conductor counts (how many separate wires are inside), and stiffness differences that decide which roll actually fits your job, because the 2-2-4 aluminum wire you pick has to match both your breaker size and how you plan to run it.
Our Picks at a Glance
How To Choose The Best 2-2-4 Aluminum Wire
Buying aluminum feeder cable is less about brand loyalty and more about matching three numbers to your job: conductor count, ampacity, and how the cable will be installed. Match all three and the cable will pass inspection and carry the load for decades.
Direct burial versus in-conduit ampacity
The same cable carries more current in open dirt than it does inside a pipe, because soil pulls heat away faster than trapped air. The Dyke quadruplex below is rated 155 Amps direct burial but only 115 Amps in duct. If your inspector or breaker plan assumes the higher number and you end up running conduit, you may need to size up. Decide between direct burial and conduit before you buy, because the ampacity rating changes with the pathway.
Conductor count decides your wiring plan
A triplex run gives you three conductors, which suits a straightforward 240V feed where the neutral is clearly striped. A quadruplex run gives you four insulated conductors, so you can use one as a separate ground and skip the extra grounding rod puzzle. A service entrance bundle gives you the most conductors of the three. Match the conductor count to your panel’s lug layout before ordering, since a partial roll cannot be returned.
Stiffness and handling on long pulls
Aluminum 2 AWG is not a flexible extension cord. It is heavy, it fights you around corners, and the heavier the cable per thousand feet, the more it resists a tight bend radius. Warm the coil in the sun and pull with wax to keep 2 AWG aluminum from fighting you around bends. Plan the pull with a helper and the stiff 2 AWG aluminum goes in without a second weekend of rework.
What beginners get wrong
The most common mistake is treating triplex and quadruplex 2-2-4 as interchangeable. A triplex direct burial cable and a service entrance bundle both say 2-2-4, but they have different conductor counts and different jacket construction. Read the conductor count line, not just the gauge line, before you commit.

In‑Depth Reviews
1. NASSAU ELECTRICAL SUPPLY 150′ Aluminum URD Dyke 2-2-2-4 Cable Direct Burial Quadruplex Secondary Wire
Our pick — over 4.5★ from 450+ verified ratings; the strongest balance of quality and price.
The 155-Amp dirt rating that lets a garage subpanel breathe.
If you are feeding a detached garage or shop panel, this is the roll that gives you the most headroom. It is a quadruplex cable — four separate insulated conductors bundled together — with two 2 AWG hots, a 4 AWG neutral, and a 4 AWG ground you can terminate on its own bar. Buried in soil it carries 155 Amps; pulled through conduit the same cable is limited to 115 Amps. That gap is the single most important number on this page, because it decides whether your breaker plan survives the inspection.
The physical build is substantial. Each phase conductor measures 0.403 inches across, the overall jacket runs 0.973 inches, and the whole thing weighs 367 lbs per 1000 feet. That weight matters on a real job: it is what makes a 100-foot pull to a backyard panel a two-person task rather than a solo one. Owners who have run it underground report the jacket holding up cleanly, and the conductors pull through conduit smoothly when waxed. What wins people over most is the build quality of the insulation and jacket — it reads as a serious cable, not a budget spool. It also undercuts the big-box stores, which is why so many buyers come back for a second roll.
Here is the honest catch. The 4 AWG neutral carries no identifying stripe on this particular spool, and a handful of buyers found themselves sorting conductors by counting rather than by sight. On a panel with clearly labeled lugs that is a non-issue — you are identifying the neutral once and you are done. On a tight, poorly lit panel it adds a few minutes of squinting. Also worth knowing: this cable is stiff. Regardless of whether you run it in a trench or a conduit, you will want to plan your bends before you start feeding.
What earns the top spot
- 155 Amps direct burial with 115 Amps available in duct (a real rating difference to plan around)
- Four insulated conductors, so the 4 AWG ground terminates separately instead of sharing a bare conductor role
- Four conductors versus the three on the Stephens triplex — the cable that gives you the most wiring options here
- Consistently praised for insulation and jacket quality across hundreds of orders
What to plan around
- The 4 AWG neutral carries no stripe, so identify it before you cut
- At 367 lbs per 1000 feet, this is a heavy, stiff pull that wants a second set of hands
Top of the list for: anyone feeding a detached panel where a dedicated ground conductor and maximum buried ampacity both matter.
Think twice if: you are working alone on a long run — this is the stiffest, heaviest cable of the three.
2. NASSAU ELECTRICAL SUPPLY 2-2-2-4 SER Aluminum Service Entrance Cable Wire (100FT)
The service entrance bundle built for running mains through walls, not trenches.
This is the odd one in the best way. Where the other two picks are direct burial cable, this is SER — service entrance cable — designed to carry power across a wall or through a structure rather than through dirt. It lists five wires in its spec line and bundles the same 2-2-2-4 conductor sizing, with a 4 AWG bare conductor included. If your project is getting power from a main panel out to a detached structure through conduit or a finished wall cavity, this is the shape you want.
Owners have used it for exactly those jobs — running a feed out to a backyard shed converted into a home office, and feeding a sub panel for EV charging. One owner warmed the coil in the sun before pulling it to make the aluminum easier to handle, which is the practical trick that keeps a stiff cable from fighting you. The value story is strong too: buyers consistently note it lands under what local electrical supply counters charge for the same SER cable, and the brand keeps a loyal following among people ordering multiple rolls.
The trade-off is length accuracy. One buyer ordered 100 feet and received 85, which stalled a project mid-pull. That is a rare miss across an otherwise clean record, but it is worth measuring the roll the day it arrives, before you cut anything. If you need a documented exact-length run, measure first and talk to the seller early.
Where it fits best: indoor and through-structure runs where a service entrance cable is the correct type — a shed office feed, a tiny house main, an EV charger sub panel.
The wrinkle to watch: verify the delivered length against the order before cutting, since at least one shipment came up short.
Reach for this if: your run goes through a wall or structure rather than into a trench.
Look elsewhere if: you need proven direct burial service — the other two picks are built for dirt.
3. NASSAU ELECTRICAL SUPPLY 200′ Stephens 2 2 4 Triplex Aluminum URD Direct Burial Cable Wire XLP USE
The lighter triplex that stretches your run without stretching your back.
This Stephens triplex is the lightest spool of the three, so your shoulders will feel the difference on a long pull. It has three conductors (three separate wires inside), a bright yellow neutral stripe, and it is a direct burial URD cable (underground residential distribution — the standard shape for running power from a house to a detached structure). The hots are 2 AWG and the neutral is 4 AWG, clearly marked by a yellow stripe. The weight spec is 264 lbs per 1000 feet, versus 367 lbs per 1000 feet on the Dyke quadruplex above. On a 200-foot pull, that 103 lbs per 1000 feet difference is something your shoulders will actually feel.
The price-to-value case is the loudest thing about this roll. Buyers report in their own words: “Very good direct burial wire. Literally 1/3 the price of electrical supply stores. Has a nice bright yellow color stripe for the neutral.” That yellow stripe is not a cosmetic detail — it means you can spot the neutral at a glance in a crowded trench or panel, which is the exact thing the quadruplex above makes you work for. Buyers also report fast shipping on quality product and come back for repeat orders.
The honest limitation is that it is triplex. Three conductors instead of four means no dedicated separate ground conductor in the bundle, so your grounding plan needs to account for that from the start. It also does not list a published direct burial ampacity figure in its data the way the Dyke cable does, so size your breaker against the manufacturer’s documentation rather than a number on this page.
The case for it: a long, straightforward burial run where value and a clearly marked neutral matter more than a fourth conductor.
What it is not: a bundle with a separate ground conductor, and there is no listed direct burial ampacity spec to lean on.
The pick for: budget-conscious installs with a simple three-conductor layout and a visible neutral stripe.
Skip this one if: your inspector wants a dedicated ground conductor bundled in — go with the quadruplex instead.
Understanding the Specs
Ampacity in dirt versus in duct
Ampacity is how much current a conductor can carry continuously without overheating. The same cable gets two different ratings depending on where it sits, because soil draws heat away from the wire faster than the air trapped inside a conduit. The Dyke quadruplex is rated 155 Amps direct burial but 115 Amps in duct. Plan around the pathway you will actually use, since a breaker sized to the burial number is oversized for a ducted run.
Conductor count and the neutral
Conductor count is the number of individual current paths inside the cable jacket. A triplex bundle has three; a quadruplex has four, which gives you a dedicated ground conductor. The neutral conductor — the one that returns current in a 120V portion of a 240V feed — needs to be identifiable, and a bright yellow stripe makes that instant. Cables without a striped neutral ask you to sort conductors by position before you terminate anything, which is fine at a labeled panel and tedious in a cramped box.

Final Thoughts: The Verdict
For most jobs, the winner in this field of 2-2-4 aluminum wire is the Nassau 150′ Dyke Quadruplex because it carries the highest published direct burial ampacity here at 155 Amps (the current it can carry safely) and gives you four insulated conductors, including a dedicated ground. If your run goes through a wall rather than into a trench, grab the Nassau SER Service Entrance Cable. And for a long, simple buried run where value and a clearly striped neutral matter most, the Nassau 200′ Stephens Triplex is the one to reach for — it is the lightest spool of the three at 264 lbs per 1000 feet. Measure your trench or conduit run, match the conductor count to your grounding plan, and any of these three will pass inspection the first time.
