Our Picks at a Glance
How To Choose The Right 2-2-2-4 Feeder Cable
Your entire setup depends on matching the wire to the distance you need to cover and the amperage you plan to draw. Getting this wrong means either buying more expensive cable than you need or, worse, a wire that runs hot under load.
Know your burial method: direct vs. conduit
Cables like the URD (Underground Residential Distribution) type are rated for direct burial, meaning you can trench them straight into the ground without a protective pipe. Service entrance (SER) cables are typically meant for above-ground runs or inside conduit. Check the rating on your chosen cable before you dig, because a non-rated cable in wet soil is a code violation and a safety hazard.
Match the ampacity to your panel
The “100A” rating on most mobile home feeders is the standard capacity for a typical service. However, if you are feeding a large sub-panel or running high-draw equipment, you might need the higher 155-amp rating that a direct-burial URD cable offers. Always match your wire’s ampacity to your breaker size and the calculated load to avoid nuisance trips or overheating.
Look at conductor construction
Aluminum is the standard material here because it’s lighter and cheaper than copper while still carrying adequate current. A 7-strand or multi-strand conductor bends and routes easier than a solid wire, which matters a lot when you’re wrestling a stiff 100-foot spool into a tight panel. Insulation thickness also plays a role—thicker insulation means more durability against abrasion and weather.

In-Depth Reviews
1. NASSAU ELECTRICAL SUPPLY 100 FT Aluminum URD Dyke 2-2-2-4 Cable
Our pick — over 4.5★ from 450+ verified ratings; the strongest balance of quality and price.
The high-capacity direct-burial workhorse that leaves 100A cables in the dust.
If you are digging a trench for a big sub-panel, this is the one to bury. It’s rated for 155 amps direct burial, which is 55% more capacity than a standard 100A feeder, giving you serious headroom for a shop, a garage, or any outbuilding with heavy loads. That extra margin means the cable runs cooler and leaves room to grow your electrical needs later.
The 7-strand aluminum conductor (sized at 2 AWG) is heavy and stiff—buyers report it’s not fun to bend around tight corners. But that stiffness translates to a rugged, 0.973-inch outer diameter cable that handles the rough stuff. It’s also built with 60 mils of insulation thickness, which is why it shrugs off the moisture and pressure of being buried straight in the earth.
Owners mention it holds up for months buried, pulls easily with a little wax, and feeds sub-panels without issues. The one recurring gripe: the neutral wire isn’t marked, so if you’re not already comfortable identifying conductors by position, add a label before you forget which is which. Owners consistently praise the build quality and value for the price.
Why it leads the pack
- 155A direct burial capacity to feed heavy loads
- 7-strand aluminum conductor for better durability
- Rugged, thick insulation rated for ground contact
What to plan for
- Stiff wire that’s hard to bend in tight spaces
- Neutral wire is not clearly identified
Grab this for: the highest-capacity direct-burial runs where 100A just isn’t enough.
Keep looking if: you need a short, above-ground run and want the easiest bending you can get.
2. Wirenco 2-2-2-4 SER Aluminum Service Entrance Cable (50FT Cut)
The short-run specialist that RV owners swear by for clean, cool connections.
This is the 50-foot cut that makes quick work of an RV hookup or a 100A sub-panel right next to the main box. It’s rated for 600 volts and 100 amps, and because it’s a Service Entrance (SER) cable, it’s designed for above-ground use in wet and dry locations—perfect for running along a wall or through conduit to a nearby panel.
You can handle this cable easily because it weighs just 0.359 pounds per foot, and its 4-wire setup—3 conductors plus 1 bare neutral—makes hooking it up simpler. Customers note it “carries 50 amps well and havent had any heat issues when in use,” ensuring reliable power for a home on wheels.
Quality is the top praise here, and the functionality earns the next-most mentions—a strong sign this cable just works without drama. The only real caution is shipping time; a few owners note it takes a few days to arrive, so plan your install around the delivery window. If you need more than 50 feet, remember this is the half-length version of the Nassau 100-foot SER option listed below.
Perfect fit for: RV hookups, mobile home service entrances, and tight 50-foot sub-panel runs where easy handling matters.
Reach for this if: you want a 100A rated cable without the bulk of a full 100-foot spool.
skip it if: your run is longer than 50 feet and you’d rather buy one continuous piece.
3. Relaxweex 50Ft 2-2-2-4 Aluminum Mobile Home Feeder Cable
The UL-listed, pre-wound reel that skips the big-box store run entirely.
This 50-foot feeder brings a UL listing (a certification mark from a recognized safety testing lab) to the table, which is a meaningful box to check when your local inspector is involved. It’s rated for 600V and 100A, and the direct burial design means you can trench it straight into the ground without conduit, saving you both material costs and installation elbow grease.
The AA-8000 series aluminum alloy conductor is the same high-grade material pros use, and the turquoise jacket resists moisture, corrosion, and sunlight. It’s rated for continuous operation up to 90°C, so it performs reliably in hot, humid conditions. The professional winding means you can unspool it right where you’re working with no birds-nest tangles.
Owners were glad to find a size Home Depot didn’t stock, and one used it for a “90’ run” without trouble. At 16.6 pounds, it’s the lightest option here, so you can haul it to the trench by yourself. The trade-off is a shorter 50-foot length—if your shop or garage is further from the panel, you’ll need to look at the 100-foot options in this guide.
Solid pick because: the UL listing removes guesswork, and the lightweight AA-8000 alloy makes it the easiest to handle in this lineup.
Choose this for: a code-friendly, direct-burial install where you value certification and easy handling.
Think twice if: your trench run exceeds 50 feet and needs a single unbroken length.
4. NASSAU ELECTRICAL SUPPLY 100′ 2-2-2-4 Aluminum Mobile Home Feeder Cable 600V
The no-nonsense 100-footer that makes short work of shop and garage installs.
For the classic 100A mobile home or detached garage feeder, this cable gets the job done with zero fuss. It’s a standard 2-2-2-4 aluminum build rated for 600 volts and 100 amps, with a 0.944-inch cable OD and a weight of 0.343 pounds per foot that keeps it manageable during a long pull. The 100-foot length is the balance for most residential lots.
Buyers have used this wire to run a 100-amp service to a 14×32 workshop, and the install “went very smoothly.” It also handles a straight run to a garage with no complaints. If you’re a DIYer who wants a predictable, well-priced cable that arrives ready to work, this is about as straightforward as it gets.
The main thing to know is shipping can occasionally lag due to supply, though the shipper is good about communicating delays. It’s also a 4-wire cable with a single-strand construction, so expect it to be a bit more rigid than multi-strand options. Still, for the price and the length, it’s a crowd-pleaser that keeps DIY projects on budget.
Smart money move: you get a full 100 feet of 100A-rated feeder without paying for premium branding.
Reach for it if: you want a full-length, budget-friendly 100A feeder for a shop, garage, or mobile home.
Look elsewhere if: you need the higher 155A capacity or a multi-strand conductor for tight bending.
Understanding the Specs
Ampacity (Current Rating)
This is the maximum current a cable can safely carry continuously. Most mobile home feeders are rated at 100 amps, which matches a standard 100A main breaker. The Nassau URD stands out at 155 amps, giving you 55% more capacity for big sub-panels or high-draw equipment. Matching this number to your breaker size is the most important safety check you’ll make.
URD vs. SER Cable Type
URD (Underground Residential Distribution) cable has a tough jacket designed to be buried directly in the earth. SER (Service Entrance) cable is meant for above-ground use or inside conduit. Choosing the wrong type—like burying a SER cable—violates code and puts your wiring at risk of moisture damage. Check the rating before you dig.
