Can se cable be used underground?
Particularly when "mobile home feeder cable" is cheaper, and contains an insulated EGC. UL white book, lists SE cable for aboveground use only and look at 338.10 (B) (4) (b) Click to expand... I don't consider in conduit to be underground. It is in conduit not directly buried in the ground.
Can I run the SER cable inside?
Yes, you can run it inside wherever you want including floor joists. The only issue that might arise is the bend radius in the LB's. Since the SER cable can be ran outside I assume you are only using the PVC for a sleeve for protection? In that case, you don't need the LB's other than for looks.
Can Ser cable be installed in PVC conduit buried under ground?
I told him the NEC doesn't allow SER cable to be installed in PVC conduit buried under ground. He really wants to use this cable since he allready bought it. I tried looking up the code reference but couldn't find anything that prohibits this.
Can You Run SE-R underground?
If you can find a prohibition from running SE-R underground, you will end this argument for good. In the past discussions, this was never achieved. In the meantime, 300.5 requires cables installed in raceways underground to be listed for wet locations, as SE-R is.
Can Ser cable be buried?
SE cables simply can't be buried, conduit or no conduit.
Can I run Ser in conduit underground?
Yes, you can run service-entrance cable (SER) in conduit, but it can't be run underground, either in or out of conduit.
Where can ser cable be used?
SER is a type SE (service entrance), Style R (reinforcement tape) cable, used as an above ground service entrance cable, a panel feeder and in branch circuits. It is most often used to deliver power from the service drop down to the meter base, and from the meter base to the distribution panel board.
What type of wire can be run in underground conduit?
THWN-2 wireTHWN-2 wire, for example, is a standard type for running through underground conduit. Use thick-walled conduit at least 3/4 inch in diameter for this application. Never use thin-wall EMT conduit for underground applications.
Can you run Ser cable outside?
SE cable also cannot be used for exterior branch circuit or feeder wiring, unless the installation complies with the provisions of Part I of Article 225 and is properly supported. USE shall not be used for interior wiring at all since it does not have a flame-retardant covering.
What is the difference between SE and Ser cable?
Basically, SER is a round service electrical cable that typically has up to four conductors and a bare neutral. The cable is designed to use above the ground in feeder panels and branch circuits. SEU is an unarmored Style U flat service electrical cable with two-phase conductors and a concentric neutral.
Is se cable rated for direct burial?
Type SE cable containing two or more conductors is permitted to have one conductor that is uninsulated. Types USE and USE-2 cables are designed and listed for underground installations including direct burial and available in both single-conductor and multi-conductor cables.
Does Ser wire need conduit?
Technically SE cable ran indoors is treated as NM cable.... I'd recommend metallic flex though if a conduit is to be used. Show activity on this post. SER is fine.
What does Ser cable mean?
aluminum service entrance cableSER cable is known as aluminum service entrance cable which is a type SE (service entrance), Style R (reinforcement tape) cable that is commonly used to deliver power from the service drop down to the meter base, and then from the meter base to the distribution panel board.
What is the code for underground wiring?
Low-voltage (no more than 30 volts) wiring must be buried at least 6 inches deep. Buried wiring runs that transition from underground to above ground must be protected in conduit from the required cover depth or 18 inches to its termination point above ground, or at least 8 feet above grade.
What can I use for electrical underground?
Electrical Cable Depth Options -deep trench, use galvanized rigid metal electrical conduit with individual conductors inside. For a 12-in. -deep trench, you can direct-bury GFCI-protected underground feeder cable with a short length of PVC conduit at the house.
Can you use GREY conduit underground?
Corrugated Conduit is a flexible conduit which can be used in a host of different applications. Medium duty (Grey) corrugated conduit is typically used above ground, and Heavy Duty (Orange) is used for underground installations.
What is SEU cable?
SEU is an unarmored Style U flat service electrical cable with two-phase conductors and a concentric neutral. SEU typically has an oval shape because of the stranded neutral conductors that wrap around the cable to create an oval shape.
What is service entrance cable?
What Is a Service Entrance Cable? Service Entrance (SE) cables are electrical cables that bring power from electrical companies to residential buildings and our homes. The National Electric Code (NEC) indicates that service entrance cables are essentially used for services.
What is the difference between copper and aluminum electrical cables?
Aluminum service entrance cables are cheaper, lighter, and generally easier to install, whereas copper cables are more durable with superior electric conductivity. Both aluminum and copper electrical cables are of excellent quality, so the choice boils down essentially to the priorities of your particular electrical project. ...
What is the hood called for a neutral cable?
The ends of the neutral conductor and the two hot conductors are then connected to the service entrance cable, which is pulled through a protective metal hood called "the waterhead.".
Is SEU cable underground?
SEU cable is sometimes called an underground service cable online, which is not true. Neither SEU nor SER is rated for use underground. The only similar cable that is suitable for the underground is USE.
Is SEU a flame retardant cable?
Both SER and SEU are flame-retardant and resistant to moisture. Both cables may have RHW, RHW-2, XHHW, XHHW-2, or THWN or THWN-2 conductors, depending on the particular product. One noticeable issue that the customer wishing to purchase SER or SEU always stumbles upon is confusion about what those two abbreviations mean due to misinformation online.
Does SEU have a ground conductor?
SEU cable has a neutral conductor, but does not have a ground conductor. Since neutral conductors and ground conductors are connected at the point of service disconnect, SEU cables can only be used up to the service disconnect to avoid significant safety concerns.
Can you pull wires through conduit?
You're better off pulling individual wires instead. Even disregarding the restriction above, you're still better off pulling individual wires through the conduit, simply due to how stiff that cable will be to pull.
Can XHHW-2 be buried in conduit?
A friend did almost the exact same job and used SER type XHHW-2, buried in conduit as recommended by an electrician. Alarms went off in my head because it is SER. However, XHHW-2 can be buried in conduit, so my question is: just because the cable is called SER does that preclude its use outside (i.e.
Can SE cables be buried?
SE cables simply can't be buried, conduit or no conduit. Why you're seeing "SER can't be buried" on this site is because the rule's right there in section 338.12 (A) of the National Electrical Code (irrelevant point 1 snipped):
Is SER cable legal underground?
SER cable isn’t legal underground, so cross that off the list. URD also called Mobile Home feeder, comes in 3-wire or 4-wire, so it’s an option. It’s legal for direct burial underground, but not for use indoors without conduit as if it was Romex or something.
Is it expensive to add spaces after a breaker runs out?
Adding spaces after you run out is extremely expensive. As such, we really like to see people splurge on excessively sized panels (in terms of numbers of spaces). If a 125A feed breaker seems like a buzzkill because your panel is only 100A, that implies a too-small panel.
Do you need a neutral conductor or ground conductor?
You'll need both a neutral and a ground conductior in addition to the phase conductors, so a service entrance cable is unsuited. you can use URD or SER (so long as you have enough conductors) but they will be harder to pull as they are designed for direct burial and so have a thicker sheath.
Can you buy THWN or XHHW?
You can buy individual wires, either THWN or XHHW. (All THWN is dual-rated THHN). You simply buy three full-size wires for hots and neutral, and one appropriately ground-sized wire for the ground. Note that URD is simply THHN or XHHW wires glued together.
