What size wire do I need for a 800 amp service?
Conductors – 800 Amp The smallest conductor size for a 240 Volt – 800 amp service will range from #6 AWG for a short 20′ run to 600 MCM for an extended run of 500′ based upon a 3\% voltage drop for a 1-Phase-3-Wire load circuit in PVC.
What size underground wire do I need?
Sizing the wires, or conductors, for an underground cable is no different than sizing for other household circuits and is typically based on the total load, or electrical demand, of the devices on the circuit….For 120-volt circuits:
| 14 AWG | 50 feet |
|---|---|
| 12 AWG | 60 feet |
| 10 AWG | 64 feet |
| 8 AWG | 76 feet |
| 6 AWG | 94 feet |
What size wire do I need for a 600 amp service?
For 600 amp service, we recommend a wire size of 1,750 kcmil.

What is 600 MCM wire?
THHN-600 MCM wire is intended for general-purpose applications as defined by the National Electrical Code (NEC). It is permitted for new construction or rewiring for the 600-volt applications.
What is 500 mcm cable used for?
500 MCM / 500 KCMIL Building Wire Applications. Perhaps the most common use for our 500 MCM Wire is for building wire applications. Additionally, 500 MCM Is often used as a large Copper or Aluminum Feeder cable in commercial and industrial electrical construction.
What wire is used for underground service?
The most commonly referred to types of Direct Burial wire are USE (Underground Service Entrance) – with a thermoset insulation – Tracer Wire and UF, or “Underground Feeder” – both with thermoplastic insulations.
How far can you run 10 2 wire underground?
The size of the wire you run to your shed depends on how far away it is and whether you use 120V or 240V. If your shed is 50 feet from your breaker box, you can use 10/2 AWG UF-B wire for a 120V circuit up to 20A. This will allow you to run multiple machines at the same time while providing light to your shed.
How many amps will 500 mcm carry?
380A
The ampacity of a 500 kcmil conductor, from the 75°C column of Table 310.15(B)(16), is 380A.
How many amps is #4 wire good for?
Wire Size and Amp Ratings
| Wire Size | 75°C (167°F) | |
|---|---|---|
| AWG | (mm²) | Copper |
| 6 | (13.3) | 65 |
| 4 | (21.2) | 85 |
| 3 | (26.7) | 100 |
What is bigger 4 0 or 250 MCM?
Circular Mils Kcmil sizes are used instead of AWG for sizes larger than 4/0 AWG. The smallest standard size is 250 kcmil, the largest 2000 kcmil. The sizes follow no obvious logic.
What size wire do I need for 200 amp underground service?
On 2015-11-09 by (mod) – wiring size information for 200 amp underground service with a 450 foot run. You didn’t specify voltage but I assume you meant 240V. At 208V you’d need bigger wires and at 120V much much bigger wires. Generally I found that for 200A at 450 ft and 240V you need to use 300 MCM copper wire or 500 MCM aluminum wire.
What size wire to run from pole transformer to house breaker panel?
Going to run from pole transformer to house breaker panel 150 feet underground. 120 volts. What cable size and conduit is required. On 2015-11-09 by (mod) – wiring size information for 200 amp underground service with a 450 foot run. You didn’t specify voltage but I assume you meant 240V.
What type of wire is used for underground service entry?
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 underground use and from its size, it’s intended to serve as an underground service entry cable.
What size wire do I need for a 15 amp circuit?
You are always safe for going to the next larger size or diameter wire for a longer run. So since a 15 amp circuit would use 14 gauge wire you could go up to number 12 wire. Be sure you’re using the proper wire type for underground feeder. I need to run 300 feet from out to panel to run 110volt motor off a 15 amp breaker…
