300 amp. For 300 amp service, you will want copper wire of size 500 kcmil to handle the load.
What size cable do I need for 300 amps?
3/0 Gauge (AWG) Battery Cable has an amperage capacity of 300 amps at a cable length of around 15 feet. 3/0 gauge battery cable is often used in main power applications heavy trucks, utility vehicles, large RV's and large water crafts.
What size wire do I need to run 100 amps 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, ...
What size wire is good for 250 amps?
You can run two 4 AWG wires to share the current if you want to operate something that requires 250 A continuously.
What wire do I need for 200 amp service?
The Short Answer: Like with aluminum, you'll need a #4/0 copper-clad aluminum wire for a 200 amp service.

A 1000 kcmil copper wire is required for 400 amp power. A copper 600 kcmil, on the other hand, can handle that much power.
Will #2 wire fit in a 100 amp breaker?
A 100 amp sub panel wiring size requirement is #4 for copper wires and #2 for aluminum wires.
What size wire do I need for a 100 amp service?
Size Wire for 100 Amp Service
Wiring a 100 amp breaker panel requires either #4 copper wiring or #2 aluminum or copper-clad wiring. Which wire used is determined by the voltage drop and length of the wiring. Many licensed electricians use #2 copper-clad or aluminum wire size.
How far can I run 10 gauge wire?
How Far Can You Run 10 Gauge Wire? You can run a 10 gauge wire up to 85 feet on a 20 amp circuit. If you opt to use this type of wire on a 15 amp circuit, it can run up to 115 feet.
How do I calculate what size wire I need?
How do you determine cable wire size? Divide the voltage running through the cable by your target current. If, for instance, 120 volts will act on the cable, and you want 30 amps to run through it: 120 / 30 = 4.
How many amps can 16 gauge wire handle?
A 16 gauge wire can handle a maximum of 13 amps. The amperage of the wire is inversely proportional to the amount of current it transmits in amps. The larger the gauge size, the smaller the wire; hence, the lesser current it can transmit.
How many amps will 8 2 wire carry?
8 Gauge Wire Amp Rating
#8 Gauge THHN Copper Stranded Wire is the most popular single conductor copper wire we carry and is RATED FOR 55 AMPS @ 90°C. Our 8 AWG THHN Stranded Wire is THWN-2 dual rated, in stock, and can ship immediately.
How many amps will 2 0 wire carry?
How many amps can the 00 gauge wire handle? 2/0 copper wire at 75°C is 175 amps, and the 00 AWG wire is custom used as a 150 amp wire size (despite the 1/0 gauge wire having 150 amp ampacity at the same temperature).
How many amps can a 6 3 wire carry?
6/3 wire is a bare copper wire which carries current and carries a current of 55 Amps approximately.
What wire size do I need to go 100 feet for a 100 amp service to a workshop?
For a 100 ampere circuit, the conductors will likely be required to be 3 AWG copper or 1 AWG aluminum.
What size wire is needed for a 100 amp sub panel?
The cable must have a wire gauge sufficient to the amperage of the subpanel—a 100-amp subpanel requires #4 copper wires or, more commonly, #2 aluminum wires, for example. (Aluminum is often used for feeder cables because the cost is typically much lower than that of copper wires.)
Can I run a 100 amp sub panel off 200 amp main?
Of course you can, you can add the 100 amp breaker to your 200 amp as long as it isn't overloaded, to start adding the subpanel you must first calculate how many yards it will be from the main panel to the subpanel, there is a formula that calculates how much friction will be on the wire at the connecting distance, ...
What is the difference between #2 and 2 0 wire?
2 AWG will handle around 94 Amps, while 2/0 AWG will handle around 190 Amps. The length of the wire must be considered as well as the % voltage drop in order for this to be true.
What size wire do I need to run 100 amp Service 150 feet?
What is the right wire size for 100 Amp service 150 feet distance? You should get 2/0 AWG Copper wire or 4/0 AWG Aluminum wire for single-phase circuits. And, 1/0 AWG Copper wire or 3/0 AWG Aluminum wire if you have three-phase circuits. For these wires, the average voltage drop should be 3%.
What do I need for a 400 amp service?
