Cloak-and-dagger & Other SEC Electric Service Wire Size Q&A

These questions & answers well-nigh the sizing of underground electric service entry wires or service laterals were posted originally at Hugger-mugger SERVICE LATERALS - topic habitation - then you volition want to exist sure to see the wire sizing table givent here.

@Deneen, actually you lot are far-more than "clued-in" than people who merely run wires willy-nilly without trying to observe out what is needed.

An underground electric service can exist run in conduit (special pipe used for electrial wiring) or it tin can be run directly if the proper UF or hugger-mugger feeder wire blazon is purchased.

The wire size you need depends on the size of electrical service (chief panel and switch) to be installed; for a small dwelling you'd typically use at least
a 100-Amp rated electric service and console.

The wire size you need is going to be given in electrical codes, selected by your installing electric contractor, based on BOTH the Ampacity (say 100A) and the total wire length - where your length of 150 ft. is pretty long, and is as well described
at
SE Cable & BRANCH Excursion WIRE SIZES vs AMPS

The table of wire sizes I'll show below is excerpted from that web page.

You lot'll see that for 100A the service entry cable is typically a #1 or a #0 gauge wire depending on whether you're using copper (smaller diameter wire) or aluminum wire.

BUT
when running the service entry cable for a longer distance, similar your 150 feet, information technology will be wire size two/0 - copper or four/0 aluminum. (More zeroes is a larger wire size).

Examples of wire sizes for longer runs are also at

SE Cable & WIRE SIZES FOR LONG RUNS https://inspectapedia.com/electric/Long-Run-SEC-Cable-Sizes.php

The wire Blazon you volition demand is one rated for burying underground and volition be marked at to the lowest degree
UF for "Secret Feeder"

At that place are boosted letters and markings that reflect more than wire properties like temperature range;

Watch out: if y'all are not familiar with proper, safe electrical wiring, making a mistake can cause a fire or kill someone. And so be sure you have aid from a qualified electrician. Also in about communities you're required to become an electrical let to do or accept done the work yous draw. The electrical inspector'due south visits and inspections are in that location to assistance keep you and everyone else safe so be sure y'all go those done.

What size of and type of conduit and service wire do I need for a small home, we are burring information technology secret from electric meter to home around 150 ft.i am a female that is totally clueless about these things. I need help

Ineed to know what size of service wire. And conduit I need for service from meter to home. I am burring information technology hugger-mugger. From meter to home around 100 ft

I need to run underground wire 300 ft. to a motel with a 150 amp console from my barn. What type and size wire volition I need?

Normally yeah;

Does the underground power company wiring size need to be changed when going from 100 to 200 amp service?

I accept a 250 foot run from the primary pole to the meter box. I accept a 225 amp breaker box. What gauge wire practise I demand for the primary run and the meter to breaker box?

Thank you

I'm putting underground electric service to my house. I have 200 amp service. I demand 200 feet of underground. What size wire exercise I demand.

Greg

Using the online calculator itself cited at the article I'll cite merely below to support a 200A load at the finish of the run

you lot'd meet an acceptable (under 3%) voltage driblet of 2.lxxx% with 350 kcmil wire

Illustration: edited from output from Southwire'south voltage drop reckoner at southwire.com

I accept a 650' run from the service pole and I'm non sure with the voltage drop what size wire is needed for a 200 amp service.

Daryll

Be sure you have the necessary permits, approvals, inspections as that will assistance your installation be safe.

I'm replacing a onetime box with new 200 amp box and running 300 foot to new trailer tin can anyone requite me any advice

Need to run a 200 amp service from pole to new house, 800' underground. What size wire?

And beware: you lot'll need an individual disconnect and fuse protection (breakers) for both of those services.

We have 400amp service split with 200amp to firm with quick disconnect. The other 200amp volition go to our barn and workshop of the other quick disconnect. My question is what size al wire should we use for 230' run to barn? It will be hush-hush 3" pic. What size quad 250 or 350?? Thanks

Using Southwire'due south voltage drop calculator, for 100A service and a 250 ft. run single phase, 240VAC, aluminum SEC buried,

1 conductors per phase utilizing a #3/0 Aluminum conductor volition limit the voltage driblet to ii.82% or less when supplying 100.0 amps for 250 feet on a 240 volt system.

If nosotros change the voltage to 120VAC the result is: 1 conductors per stage utilizing a #400 Aluminum usher will limit the voltage drop to two.94% or less when supplying 100.0 amps for 250 feet on a 120 volt organisation.

Typically, the maximum allowed voltage drib for residential installations is 3% that's why I chose that number. You can see you'd be ok with direct buried three/0 Al.

You may want to run your wire in 3" conduit - double check with what your local electrical utility volition accept.

Check out the definition of VDI - voltage drop index, and likewise "Maximum Wire Length vs Wire Size & Circuit Amps" at SE Cable SIZES vs AMPS inspectapedia.com/electric/Electrical_SEC_Sizes_Amps.php and of course get to UF (underground feeder) rated wire.

what size of hush-hush wire exercise I need to run a 100 amp service, 250 feet away?

You are always safe for going to the adjacent larger size or diameter wire for a longer run. So since a 15 amp circuit would use 14 guess wire you could get up to number 12 wire. Be certain you're using the proper wire type for undercover feeder.

I need to run 300 feet from out to panel to run 110volt motor off a xv amp billow... What estimate wire do I need?

Going to upgrade to a 200 amp service. Going to run from pole transformer to house breaker panel 150 feet underground. 120 volts. What cablevision size and conduit is required.

Sure Mike

Yous didn't specify voltage but I assume you meant 240V. At 208V yous'd need bigger wires and at 120V much much bigger wires.

At that place are many wire sizing tables online and in the NEC, and some reasonable online wire size calculators

Generally I found that for 200A at 450 ft and 240V yous need to use 300 MCM copper wire or 500 MCM aluminum wire.

You'll want to cheque again the NEC tables and UF notes.

see http://www.jhlarson.com/

Can you provide wiring size data for 200 amp underground service with a 450 foot run.

Thanks
