What size wire is needed for 600 amps?
For 600 amp you will need a 1500 kcmil-gauge wire.
What size wire is rated for 500 amps?
Wire Size and Amp Ratings
| Wire Size | 75°C (167°F) | |
|---|---|---|
| AWG | (mm²) | Aluminum |
| 350 | (177) | 250 |

What are the conductor sizes?
The Gauge size of stranded conductors is often expressed as a combination of the overall size and the size of the individual strand. EXAMPLE: 16 AWG 26/30 – 16 represents the overall gauge size, 26 is the number of strands, 30 is the gauge size of each of the 26 wires.
What size ground do I need for a 400 amp service?
MIN. SIZE OF EQUIPMENT GROUNDING CONDUCTORS (EGC) for Grounding Raceway & Equipment
| Rating or setting of Automatic Overcurrent Device (OCPD) in Circuit ahead of Equipment [i.e Circuit Breaker]. Not exceeding (Amps) | Size (AWG or kcmil) | |
|---|---|---|
| 100 | 8 | 6 |
| 200 | 6 | 4 |
| 300 | 4 | 2 |

What size conduit do I need for a 400 amp service?
3
What size of conduit is needed for underground services? There is a letter A. The conduit should be less than 150′ long for 200 Amp service entrance. The conduit for 400 Amp service entrance will be 3.
What is the largest conductor size?
7/0, the largest size, is 0.50 inches (500 mils or 12.7 mm) in diameter (250 000 circular mils in cross-sectional area), and the smallest, No. 50, is 0.001 inches (1 mil or 25.4 μm) in diameter (1 circular mil [cross-sectional area] or 0.7854 millionths of a square inch).
What is the largest size AWG conductor?
0000 AWG
In AWG, the larger the number, the smaller the wire diameter and thickness. The largest standard size is 0000 AWG, and 40 AWG is the smallest standard size. It may also be called Brown & Sharpe wire gauge or simply the gauge of the wire. AWG is for single-strand, solid, round, electrically conductive wire.
What size Ufer do I need?
20 ft
The requirements for a concrete-encased electrode, commonly called a “Ufer Ground” are included in 250.52(A)(3). This is an electrode developed by using electrically conductive reinforcing bars or bare copper conductors not smaller than 4 AWG at least 20 ft in length.
How do you measure a ground conductor?
The size of the grounding electrode conductor is based upon the size of the largest ungrounded service-entrance conductors or ungrounded derived conductors (such as for a separately derived system) or the total equivalent area for parallel conductors (AWG/kcmil).
