Feeding a 200-amp sub-panel, shop, or mobile home starts with one brutal decision: which heavy aluminum service cable do you bury or pull, and how do you avoid a roll that fights you from the first foot? All three 4/0 4/0 2/0 cables carry the load, but they differ in conductor count, stiffness, and bendability.
I’m Min — the founder and writer behind Gadgets Feed. 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 are choosing the best 4/0 4/0 2/0 aluminum wire for a service entrance or feeder, so understanding burial ratings and ampacity before you buy is the only way to avoid a costly re-pull.
Our Picks at a Glance
How To Choose The Best 4/0 4/0 2/0 Aluminum Wire
Before you buy, know what the numbers mean: 4/0-4/0-2/0 refers to two 4/0 AWG (American Wire Gauge, a standard thickness measure) hot wires and one 2/0 AWG neutral wire. The real decision depends on the fourth wire—some cables include a separate ground, which determines if you need a ground rod or a dedicated conductor running back to your main panel.
Count the conductors before you count the feet
A triplex URD cable carries just three conductors — two hots and a neutral — and relies on a separate ground path. A quadplex or SER cable adds a fourth conductor for the equipment ground. Your local code and panel type dictate which one you actually need, so matching the cable’s wire count to your planned hookup prevents an inspection failure.
Match the jacket to the installation method
Direct-burial-rated cable (URD) can go straight into a trench, while service entrance cable (SER) is built for running from the meter to the panel, often inside or along a structure. Choosing a cable rated for the wrong environment — like burying a non-rated jacket — is a mistake that costs time and labor to correct.
Expect stiffness as a feature, not a flaw
Large aluminum conductors are inherently rigid, and every review set for this category mentions how hard they are to bend. Plan your conduit path with sweeping bends, not tight 90-degree corners, and you will save yourself the most frustrating part of the install.

In‑Depth Reviews
1. Nassau Electrical Supply 200′ Sweetbriar Aluminum URD 4/0 4/0 2/0 Cable
Our pick — over 4.5★ from 30+ verified ratings; the strongest balance of quality and price.
The direct-burial workhorse that wins on price per foot for long underground runs.
Choose this triplex URD (underground residential distribution) cable when you need to run power from a pole drop to a workshop or outbuilding through a trench. Buyers report using roughly 70 feet of it for a pole drop to a workshop panel, with steady power and no issues after years of service.
The jacket is stiff. This is 1.389 inches in outer diameter, and the aluminum conductors inside are rigid, so you will fight it through conduit. Owners mention it fits in 1-1/2-inch conduit per code, but they are blunt that you should not dream of making a tight 90-degree corner with it — plan sweeping bends or direct burial instead.
This cable has only three conductors, so it skips a separate ground—unlike the quadplex (four-wire) options below. Its 600-volt rating and 19-strand construction (multiple thin wires twisted together) make it flexible enough for a dedicated underground feeder. The value stands out: customers note pricing the identical wire at a local electrical supplier and finding it roughly six hundred dollars more expensive for the same product.
Real-world verdict: For a straight trench run to a detached structure, this delivers the lowest cost per foot for a true 4/0 4/0 2/0 build, and it holds a 4.6-star rating from 30 buyers.
Stiffness warning: Treat this as a straight-shot cable — the rigidity that makes it durable also makes sharp conduit bends nearly impossible.
Reach for this if: your project is a direct-burial feeder with a separate ground rod, and you want the most cable for your money.
Look elsewhere if: you need a fourth ground conductor included or you must navigate tight conduit corners.
2. NASSAU ELECTRICAL SUPPLY 75′ 4/0-4/0-2/0-4 Aluminum Mobile Home Feeder Cable
The complete four-conductor kit that inspection-ready mobile home and shop owners trust.
This is the quadplex answer for a 200-amp mobile home underground service, and it earns its premium place by carrying the equipment ground you often need for a compliant install. The cable construction reads 4/0-4/0-2/0-4, meaning two 4/0 hots, a 2/0 neutral, and a separate 4 AWG grounding conductor all in one jacket — no extra ground wire to pull separately.
Buyers confirm the length claim, reporting they ordered 180 feet and received exactly that, with no degradation after nearly three years of installation. The jacket is the largest of the three picks at 1.54 inches in outer diameter, and at 0.778 lbs per foot it is noticeably lighter than the Wirenco option above.
That lighter weight per foot is a real advantage when you are dragging a 75-foot roll across a yard, yet the cable still carries the full 200-amp allowable ampacity with a 600-volt rating. The recurring shipping complaint appears in a small share of reviews, so inspect the spool on arrival, but the core product itself earns consistent praise as the correct conductor set for a 200-amp mobile home underground service.
What the install crew loves
- Four conductors mean the ground is already in the jacket
- Lighter at 0.778 lbs per foot than the SER rival
- Verified exact length delivery on long orders
What to watch on delivery day
- An occasional spool arrives with shipping damage
- Largest outer diameter at 1.54 inches needs a wide trench
Best suited for: the mobile home or shop owner who needs a self-contained ground and wants a proven, code-friendly quadplex.
Who should skip: anyone running just three wires to a panel that grounds separately — you would pay for a conductor you do not need.
3. Wirenco 4/0-4/0-4/0-2/0 SER Aluminum Service Entrance Cable (20FT Cut)
The short, precision-cut SER spool for meter-to-panel runs that skip the burial trench entirely.
This cable is built for the classic service entrance job — delivering power from the service drop down to the meter base and then onward to the distribution panel board. It is a four-conductor SER cable with three 4/0 AWG conductors and one 2/0 AWG ground, and its 7-strand construction makes it the stiffest of the three at 0.968 lbs per foot.
The 20-foot cut length sets this apart. Unlike the 75-foot and 200-foot rolls, this suits a job needing a specific, shorter span. Its ampacity (maximum safe current) is clearly rated at 200 amps at 90 degrees Celsius (194 degrees Fahrenheit), which marks the thermal limit before the conductor must be derated (reduced in capacity). Buyers call it great wire for the money and confirm the specs match exactly as advertised.
This cable weighs 0.968 lbs per foot, 24% heavier than the NASSAU mobile home feeder, making it harder to maneuver. A single buyer flagged a missing-markings issue — noting NEC 310.120 requires conductor identification every 24 inches — so verify your local inspector’s expectations before cutting, since returns get difficult once the cable is shortened.
The straightforward call: if you need a precise short run from meter to an interior panel, this gives you a true four-conductor SER at 200 amps without paying for surplus footage you will never unroll.
The trade-off: heavier per foot than the competition and a potential marking issue that warrants a quick check with your AHJ.
Go with this when: you are wiring a panel directly and you know your exact length is around 20 feet.
Think twice if: you need direct-burial rating for an underground trench — this is a service entrance cable, not a URD.
Understanding the Specs
Conductor count and configuration
The 4/0 4/0 2/0 label tells you the gauge (thickness) of each wire inside the jacket—two 4/0 hot wires and one 2/0 neutral. If you see a fourth number, such as 4/0-4/0-2/0-4, that trailing digit is a separate grounding conductor, and its presence determines if you need an additional ground wire or a ground rod for your installation.
Weight per foot and outer diameter
Feeder cable is heavy, and the difference between 0.778 lbs and 0.968 lbs per foot adds up fast across a long roll. Outer diameter — between 1.389 and 1.54 inches here — determines the minimum conduit size and trench width you need, so check both numbers before planning your pull.
