Buried or hole-and-corner electric service entry cable ampacity & secret electrical service ampacity ratings:

How to determine the size, capacity, or ampacity of electrical service at a edifice.

This article explains how to estimate the electrical service size, (or “electrical power” or “service amps”) at a building by visual examination of the buried service entry cables and other details that are available by simple visual inspection.

We also provide an ARTICLE Alphabetize for this topic, or you can endeavour the page superlative or lesser SEARCH BOX as a quick manner to find information you need.






Hole-and-corner Electric SERVICE LATERALS – delivering current to a building

Electrical Services provided through underground conduit do not permit visual inspection of the service usher prior to the electric meter and actual conductors are visible only in the service console.

It is possible to approximate at the cablevision run in a conduit by the diameter of the conduit itself [Tabular array 2.] Merely for conductors from the utility company’southward drop to the meter, conduit size sets only the maximum conductor that could be contained, not necessarily the actual size.

Underground Electric Service Burial Depth

Electrical service wire burial depth guide adapated from Snohomish Public Util Div cited at InspectApedia.com

How deep below the ground surface or below a concrete slab, walk, or a driveway must we bury electrical service entry cabling?

Watch out: Your local electrical inspector is the last legal authorisation on the required depth at which to bury an electrical service entry cable, but here are some common depths:

[Click to overstate whatsoever image]

Typical Undercover SEC or Electrical Wire Burial Depth

Type of Circuit Minimum Burial Depth [6]
Direct Burial of SEC Cabling or Conductors 600 mm or 24 in
Rigid metallic conduit or intermediate metal conduit 150 mm or vi in
Nonmetallic raceways [ane] 450 mm or 18 in
Residential branch circuits 120VAC or less [2] 300 mm or 12 in
30V or less special circuits 150mm or 6 in.

Notes to the table in a higher place

  1. Raceway must be listed for direct burying without concrete encasement
  2. Residential circuit must accept GFCI protection and maximum overcurrent protection of 20A
  3. Instance: irrigation or mural lighting circuits with UF or in a listed cablevision or raceway
  4. Burial depth: ways below the surface of the soil; some codes refer to this as the “required encompass” or “required depth of soil cover” over the electrical conduit or cable or UF (Underground Feeder)
  5. Source: Carmel CA’south Building Prophylactic Division, cited below.
  6. Typical maximum is 48″ – e.k. from Snohomish County PUD
    24″ to 48″
    is the recommended depth for electric SEC cable conduit.

Other electric wire burial depths from Snohomish – cited below

  • Metal conduit carrying SEC – at least half dozen inches below soil top
  • Metal conduit carrying SEC – 4 inches under a four-inch concrete slab.
  • Metal conduit conveying SEC – no less than 18 inches
  • Metal conduit conveying SEC – no less than 24 inches

In the UK and other countries the required depth of electrical cables will vary from the higher up.

No surprise that the neutral or footing conductors in some electrical wire products may be a smaller wire guess than the current conveying conductors.

My house was built in 1976. The neutral usher is made by Philips and is labelled TWH iii. The 2 hot wires betwixt the meter base and panel are labelled as PHH 1. I accept not been able to observe specs or ampacity numbers for this wire. Is this an earlier vintage of RHH 1 ?

@Randall,

200 amp service 135 anxiety length what size teck cable would I need

@Nib,

At the WIRE SIZE & AMPACITY TABLES

You’ll see #8 copper wire is rated for 40 Amps

As y’all’ll see in the articles in this series you’ll see some voltage drop at longer runs.

Also it’s ever safer to fuse at a lower amperage such as 30 amps on that wire.

I take underground 100 anxiety to garage. In panel is 2 6g wire and two 8g wire (copper) If I use the 8 judge for ability and 6g for neutral what size breaker should I employ

I need to run 775ft from meter pole to 100 amp box in a cabin. what size and kind of directly bury cable should I use? I know there will be a voltage drop its OK.

Don you’re quite right, and there may already exist such electrical pattern apps, though I suspect designers volition be darn scared near pretending they can guide you safely through electrical wiring when in that location are many safety details that would be apparent to a licensed electrician merely may not be apparent thus not mentioned nor considered past a normal person who’s non already trained in the field.

Meanwhile this article series does take a stab at giving general wiring guidelines with simple tables: amps, altitude, cable sizes, etc. Please accept a look.

In this day and historic period, can’t someone build an app where you start with a specific subpanel, plug into the app what breakers you intend to install (how many 240, how many 120, what amps for each billow) and so what distance information technology is to the main panel and it tells you what wire size y’all demand, how many amps on the main panel disconnect breaker, what hole-and-corner conduit as applicative etc.?

Seems similar the rules ought to be known well enough to go the computers in our life to figure out the hard stuff. Example, I’m building a shop 100 anxiety from the main console and intend on having a 240v split Air-conditioning requiring a 20 amp breaker.

The rest of the sub panel will exist 120v normal loads of outlets and lights of almost half-dozen breakers 15 amps each. Do I demand to size my feeder wire for 100 amps of 120V or am I sizing for 100′ of 240 V 50 amps? I mean each hot leg isn’t going to encounter the total panel load? Be so elementary to plug the components into an app and it tell me what the wire requirements would exist.

Thanks, Mike, that’southward a helpful question.

Translating the markings & letters on your electrical wire: CSA USEB90 2CDR AWG4/0 1 CDR AWG1 is broken downward and explained as follows:

CSA = Canadian Standards Association

USEB90 = USEB-90 Underground Service Entrance Cable consists of two compact aluminum conductors individually insulated with RW90 XLPE insulation, laid in parallel, with a helical plain copper wire serving and an overall PVC jacket covering. The copper wire serving is the neutral. The product meets the USEB-90 cable requirements of CSA.

So we know your wire is rated for hugger-mugger use and from its size, information technology’due south intended to serve every bit an hugger-mugger service entry cable.

For completeness I explain that OTHER electric wires designated equally designed for underground utilize will be marked “UF” for “Underground Feeder” – a non-metallic cablevision that can be used in wet locations or in united nations-protected locations such equally by burial the wire directly in the ground (without a protective conduit). The usual color for UF cable is gray. Where used higher up ground the cable should be marked UF_B (sunlight resistant).

2CDR = 2 conductors

AWG4/0 = wire estimate or size is 4/0 (for aluminum wire that’s suitable for 200A)

1 CDR = one conductor

AGW1 = wire gauge 1

Then we have two iv/0 conductors (those will exist the current carrying wires) and one AWG-ane conductor (that’ll be the neutral conductor – or grounded conductor and and so is a smaller size)

Moderator reply: Guidelines for USEB90 Feeder Cable

Thanks, Mike, that’south a helpful question.

Translating the markings & messages on your electrical wire:
CSA USEB90 2CDR AWG4/0 1 CDR AWG1
is broken downward and explained as follows:

  • CSA

The copper wire serving is the neutral. The product meets the USEB-90 cable requirements of CSA.

So nosotros know your wire is rated for underground use and from its size, information technology’southward intended to serve as an underground service entry cablevision.

For abyss I explicate that OTHER electrical wires designated as designed for undercover use volition be marked “UF” for “Underground Feeder” – a non-metal cablevision that can be used in wet locations or in un-protected locations such equally by burying the wire directly in the ground (without a protective conduit). The usual color for UF cablevision is greyness. Where used above basis the cable should be marked UF_B (sunlight resistant).

  • 2CDR
    = 2 conductors
  • AWG4/0
    = wire gauge or size is 4/0 (for aluminum wire that’s suitable for 200A)
  • one CDR
    = 1 conductor
  • AWG1
    = wire judge ane

where

  • AWG
    = American Wire Gauge (AWG) likewise referred to as the Brown & Sharpe wire gauge. This is a standard method of describing wire sizes or “gauges” that has been in use in North American since 1857.

    AWG is further defined and used in

    ASTM Standard B 258, Standard Specification for Standard Nominal Diameters and Cross-Exclusive Areas of AWG Sizes of Solid Round Wires Used as Electrical Conductors, available from ASTM or astm.org

So putting together all of those wire markings into a prose description, nosotros have two iv/0 conductors (those volition be the current conveying wires) and 1 AWG-i conductor (that’ll be the neutral conductor – or grounded usher so is a smaller size)

My goodness, Billy, I’ve never been mistaken for a calculator-bot. Probably a bot would not make spelling errors when trying to respond when only a smartphone was at paw. Cheers for the feedback.

I’m dorsum at the lab and have access to a keyboard for a more than-detailed answer to your electrical service UF wire size question.

I also promise you’ll assist me avoid re-creating “off the cuff” information that we’ve got more than thoroughly stated and organized in the commodity(s) to which I refer you.

[Click to overstate whatever image]

At the page I recommended where we have a detailed table of SEC size vs amps for both aluminum and copper wires,

the SEC Cable SIZE table in

SE Cable & WIRE SIZE TABLES vs AMPS you’ll see the data that I excerpted in my earlier reply to y’all. There is non a single “correct” respond to your wire size question without a little more information.

In that more-thorough data, we see that choosing an electrical service wire size bears because not only ampacity only also
run length
(as you know) and
temperature rating
of the wire.

For case the table notes that the rated ampacity for 2/0 or 00 depends:

Usher Rating Temperature of 60 / 75 / ninety °C permits an amperage of 145 / 175 / 195 respectively for 2/0 – 00 COPPER

while for an
ALUMINUM SEC wire the ratings were 115 / 135 / 150 Amps at those temperature ratings.

That’s why you’re going to find that not two/0 wire (every bit yous offered) bur rather iv/0 will exist where yous start for Aluminum SEC cabling if your electrical service size is 200 Amps.

Keep in heed that manufacturers may produce and certify aluminum wire – and mark information technology correct on the wire – for ampacities different than the standard tables that we excerpted from the US National Electrical Code.

Please NOTICE that the manufacturer’southward remarks that I will site in the side by side posting are the same equally in our table that I recommended, that’south iv/0 Aluminum for a 200A service, and that’s BEFORE going to a larger size that might be required for longer runs.

Thanks for the discussion – getting SEC wire size right is critical for safe and so your question can assist other readers. Beneath: information for COPPER SEC wire every bit an example.

Finally:

Of course you want to follow the communication of your electrical power company and your onsite electrician who can meet the actual site conditions and requirements – something that I, a mere semi-bot – cannot exercise from mere e-text sent via internet to our function here on the other side of the U.s.

Your local electric inspector is the final legal say-so on what’southward permitted and acceptable for your installation.

Sorry if I’1000 being dense but that table is not consistent with what I’ve been told past local professionals or the reps from the power company. Are you a real person or a computer bot? Canned answers are not what I’m looking for.

Check the SEC Cable SIZE table in

SE CABLE & WIRE SIZE TABLES vs AMPS

For 200A and 150 ft, and select a UF or Underground Feeder rated cable type. That’s more critical than the number of strands.

You’ll see that if you’re using 2/0 wire for 200A you’re almost certainly using copper, not aluminum.

An aluminum SEC for 200 A is typically 4/0 and cloak-and-dagger will be labeled UF for “hole-and-corner Feeder”

I’yard not sure what question you are asking; but in most countries the wire from the utility company’southward pole to the service connection at the building at a masthead is the responsibility of and is installed by the electric company and is sized by them.

In some locations, particularly where long lines must exist run from the utility company’s power line across one or more poles across private holding to a building, the belongings owner is responsible for installing the required poles; or service wiring may run hush-hush.
