6/2 AWG wire6/2 AWG wire for 150 feet.

What size wire do I need for a 100 amp underground 150 ft run?

#00 AWG wire





Wire Size For 100 Amp Sub Panel 150 Feet Away



It’s too small. 100 amp service 150 feet away from the sub panel requires #00 AWG wire (also known as 2/0 AWG wire). This wire has a median ampacity of 175 amps; more than enough than the required minimum 162.5 ampacity.

What size wire do I need to run 50 amp service for 150 feet?

To run 50 amps at 150 feet, you can use No. 4 AWG. The larger the wire diameter is defined by the smaller numbers on a wire.

What size wire do I need to run a sub panel?

The cable you run from the main panel to the subpanel also depends on the amperage rating. You can use 10 AWG, three-conductor wire for a 30-amp panel, but for a 60-amp one, you need 6 AWG wire. If you’re installing a 100-amp panel, you need 4 AWG copper or 2 AWG aluminum three-conductor cable.

How far can you run 10 gauge wire for 30 amps?

How far can you run 10 gauge wire for 30 amps? 10-gauge wire is usually used for short 30 amp runs. If you plan on going over 150 feet, 8-gauge wire or thicker will be needed.

What size wire do I need to run 150 feet?





150 Foot Run – A 120-volt circuit on a 20 amp breaker will require 6/2 AWG wire for 150 feet.

How far can you run 6 gauge wire for 50 amps?

For every 100 feet, voltage drops by 20%.



Example: 50 amp wire is usually the 6 AWG (we require at least 62.5A and 6 AWG can handle 65A). If you have to power an electric device 100 feet away, you need 20% amps more.

What size wire do I need to run 300 feet?

for 300 feet for 100 amp rated service I would use Aluminum direct burial 1/0-1/0-1/0-1/0, the forth can be as low as #4 for the ground (but also in conduit, even if in conduit must still be rated underground wire and required by code also) Also note the size wire the breaker can handle, cannot cut strands to make fit, …

Will 10-gauge wire carry 50 amps?

A 10-gauge bare copper wire can carry a 50-amp load, but the resistance in the cable will cause it to heat up substantially.

How far can you run wire before voltage drop?



As an example, for a 120-volt circuit, you can run up to 50 feet of 14 AWG cable without exceeding 3 percent voltage drop.



For 120-volt circuits:

14 AWG 50 feet
12 AWG 60 feet
10 AWG 64 feet
8 AWG 76 feet
6 AWG 94 feet


How far can you run 200 amp service underground?

You’ll see that if you’re using 2/0 wire for 200A you’re almost certainly using copper, not aluminum. On 2020-07-02 by BILLY M. The distance is roughly 150 feet.

How many receptacles can be on a 20 amp circuit?



The answer to the question how many outlets on a 20 amp circuit is ten outlets. Always comply with the 80% circuit and breaker load rule, allowing a maximum load of 1.5 amps per receptacle. Remember that your circuit, wire sizes, and outlets must be compatible to avoid overheating and electrical hazards.

How do you calculate cable length?

Quote from the video:
Quote from Youtube video: Size and the cable resistance for a single cable the length of the cable is 1000 multiplied by the measured resistance. And then divided by the milli ohms.

How do I calculate the amount of electrical wire?

Estimate the Length of a Wire

  1. Start by measuring the resistance of the length of wire. Use an ohmmeter to measure the resistance of the wire. …
  2. Enter the resistance into the calculator.
  3. Select the wire gauge on the calculator.
  4. Click the “Calculate Wire Length” button.


How do you calculate wire size in a load?



Full Load Current = (KVA · 1000) / (1.732 · Voltage): Full Load Current = (100 · 1000) / (1.732 · 415) = 139 Amp.



Let’s select 3.5 core 95 Sq.mm cable for single run, short circuit capacity = 8.2 KA.

  1. Current capacity of 95 Sq.mm cable is 200 Amp, …
  2. Total derating current of 70 Sq.mm Cable = 200 · 0.93 = 187 Amp.

How much voltage drop is acceptable?

How Much Voltage Drop is Acceptable? The National Electrical Code says that a voltage drop of 5% at the furthest receptacle in a branch wiring circuit is passable for normal efficiency.

Does cable length affect voltage?

Long lengths of wire have more resistance than short lengths. Thus, long lengths of wire will cause a larger voltage drop than shorter lengths.

Why do you upsize wire for voltage drop?

A larger conductor means less voltage drop and higher efficiency.
