Does MHF cable need to be in conduit?
MHF is direct burial rated and doesn’t need to be installed in conduit except for where it emerges from the earth. The NEC does not prohibit it from being installed in conduit.
What type of wire is MHF?
Aluminum Mobile Home Feeder Wire, or MHF cable, is an aluminum cable with XLPE insulation that is used for permanent wiring in mobile homes where it is mostly used as a service entrance cable.
Is aluminum wire as good as copper?
It’s often preferred, in fact, over aluminum wiring because of its high tensile strength. The tensile strength of copper is roughly 40% higher than that of aluminum. With a higher tensile strength, copper wiring is less likely to break than aluminum wiring.
What gauge wire do I need for 100 amp service?
Installation of 100 amp electric service or subpanel needs a #4 AWG copper wire or #2 AWG aluminum or copper-clad wire inside a minimum 1.25 inch, schedule 40 or 80 PVC electric conduit for underground service.
Can MHF be direct buried?
Although MHF is suitable for direct burial, it must be installed in conduit for physical protection where it enters and emerges from the soil or anywhere it is subject to physical damage (for example, on a wall).
Can MHF be used indoors?
USE-2 by itself cannot be run indoors. Many USE-2 conductors (or assemblies often called URD or MHF) are marked RHH/RHW-2 and if so, can be run indoors, but do need to be run in conduit indoors.
How many amps will #6 aluminum wire carry?
50A
Example: A 6 AWG aluminum wire has a rated ampacity of 50A. 80% NEC rule states that you can only load the wire up to 80% of the rated ampacity. That means that a 6 AWG aluminum wire can handle 40 amps of electrical current or less.
Can you bury MHF cable?
What is 2 AWG aluminum wire for?
#2 Stranded Aluminum XHHW-2 Wire XHHW-2 are primarily used in air duct, conduit or recognized raceways for services, feeders and branch circuit wiring as specified in the National Electrical Code.
Is multi strand aluminum wiring safe?
It is important to note that multi strand aluminum wiring is considered safe and in use in most homes today in addition to copper wire. Aluminum Wiring was used in the construction of roughly 1.5 million U.S. homes built between 1965 and 1973.
Can you still buy aluminum wire?
Aluminum wiring is not illegal, but it is no longer up to code and new homes are now built with copper wiring. If you are thinking about buying or selling a home with aluminum wiring, you will be ok as long as you follow the instructions on how to deal with it. How much does it cost to rewire a house?
What is the wire size for a mobile home feeder?

What is the voltage rating of the aluminum feeder cable?
Voltage rating is 600 volts. Aluminum Mobile Home Feeder cable has a compact strand soft drawn 8000 series aluminum conductor, per ASTM B-800 & B-801. Aluminum Mobile Home Feeder cable has a type USE2/RHH/RHW-2 cross linked polyethylene (XLP) insulation. The conductors are cabled together with a green XLP insulted aluminum ground.
What is a rhw-2 wire used for?
Use as connection between pole or pedestal-mounted equipment and a mobile home Type RHH or RHW-2 or use conductors are used with conduit as specified in the National Electric Code 1
What kind of electrical wire do you use for a mobile home?
