4/0-4/0-4/0-2/0 Aluminum Mobile Home Feeder Cable

Two 4/0 AWG aluminum hot conductors and one 2/0 AWG aluminum insulated neutral. A three-conductor configuration for service entrance or two-wire feeder applications where a separate equipment grounding conductor is not run with the cable.

A 4-conductor aluminum cable for feeding power from a service panel to a mobile or manufactured home. Modern MHF uses USE-2 or XHHW-2 conductor insulation, both listed for direct burial and wet locations. Three-conductor variants like 4/0-4/0-2/0 are used for service entrance runs where an equipment grounding conductor is not required in the cable itself.

For a residential dwelling service, 4/0 aluminum is rated for 200A under the reduced-sizing allowance in NEC 310.12. For non-dwelling applications, the standard 75°C ampacity from NEC 310.16 applies: 4/0 AWG aluminum is rated 180A at 75°C. Because this cable has no equipment grounding conductor, it is limited to service entrance and two-wire feeder applications.

Yes. The individual conductors are USE-2 or XHHW-2, both listed for direct burial in wet locations. Follow NEC 300.5 for burial depth: 24 inches for direct-buried residential feeders under 600V, 18 inches under a concrete slab, and shallower depths where protected by conduit.

The conductors are typically USE-2 or XHHW-2, both listed to UL 854 for service entrance and UL 44 for the conductor insulation. USE-2 stands for Underground Service Entrance, and the -2 suffix means 90°C rated in wet locations. XHHW-2 is cross-linked polyethylene with the same 90°C wet rating. Voltage rating is 600V.

Yes. MHF is commonly used for service entrance runs, pole barn feeders, detached garage subpanels, and outbuildings. The 4/0-4/0-2/0 three-conductor version is most often used as service entrance conductors from the meter to the main disconnect, where the equipment grounding conductor is not required in the cable itself.

Not as an unsupported overhead drop. For a short span, run the MHF inside conduit between the buildings, or use quadruplex URD, which comes with a built-in messenger for aerial residential feeders.

Yes, but the splice needs to be made inside a weatherproof, listed junction box using connectors rated for the conductor size and material. NEC 300.13 and 300.15 cover splice and box requirements. Direct-buried splices are allowed only if the connectors and covering are listed for direct burial. Most installations avoid buried splices by running a single continuous length.

Voltage drop, not ampacity, is the sizing limit at long distances. Rule of thumb for a 200A load on 4/0 aluminum at 240V single phase, keeping voltage drop under 3%: about 175 to 200 ft. For runs beyond 300 ft, upsize to 250 MCM or 350 MCM. Do the actual voltage-drop calculation for the specific load and run length before ordering.

At 200A load, 240V single phase, on 4/0 aluminum, expected voltage drop is roughly 3% at 200 ft, 5% at 325 ft, and 7% at 455 ft. Standard practice keeps total voltage drop (feeder plus branch circuits) under 5%, with the feeder itself under 3%. Use a proper calculation with the actual load current before ordering.
