No number four is only good for seventy-five amps. I am pulling that out of my head, my book is in the truck. I think for a one hundred amp service you need at least number two. I will check for sure tomorrow and post it on my message board. Remember the length of the run is a factor. A quick web search will give you some calculators to help you figure this out for your application.
95 Amps assuming you're using THHN type. Refer to page 297, Article # 310.15 of NEC 2005 Handbook, or page 336, Article # 310.15 of National Electrical Code Handbook.
NEC 2011 explains on the top of this table:
Table 310.15(B)(16) (Formerly 310.16) Allowable Ampacities of Insulated Conductors rated UP TO AND INCLUDING 2000 Volts, 60 Degrees C Through 90 Degrees C ( 140 Degrees F Through 194 Degrees F), Not More Than Three Current-Carrying Conductors in Raceway, Cable, or Earth (Directly Buried), Based on Ambient Temperature of 30 Degrees C (86 Degrees F)*
A #4 copper conductor with an insulation factor of 75 or 90 degrees C is rated at 85 amps.

How many amps will a 4 gauge aluminum wire carry?
A 4-gauge aluminum wire can typically carry up to 70-85 amps of current for general household wiring applications. It is important to always consult with local electrical codes and a professional electrician to ensure safe and compliant electrical installations.
How many amps can 16 gauge wire carry at 120 vac at 25 feet?
A 16 gauge wire can typically carry around 10-13 amps at 120V AC over a short distance like 25 feet. It's important to follow standard safety practices and consult with an electrician to ensure that the wire gauge is appropriate for your specific application and local electrical code requirements.
How many automotive amps can 30 foot strand of copper wire carry?
The number of automotive amps a 30-foot strand of copper wire can carry depends on the gauge (thickness) of the wire. For example, a 30-foot strand of 10-gauge copper wire can typically carry up to 40-50 amps for automotive use, while a 30-foot strand of 12-gauge wire might be limited to around 25-30 amps. It's important to consult wire ampacity tables and consider factors like temperature and voltage drop to ensure safe and effective performance.
How many amps for 14 wire how many amps for 12 wire?
A 14-gauge wire can typically carry up to 15 amps of current, while a 12-gauge wire can handle up to 20 amps. It's important to follow the manufacturer's guidelines and electrical codes when determining the maximum current for a specific wire size.
What gauge wire would you need to carry 100 amps at 12 volts dc?
A #3 copper wire with an insulation factor 90 degree C is rated at 105 amps.
How many amps will 4.0 gauge wire carry?
140 AMPS
What gauge of wire is needed to carry 200 amps?
3/0 gauge
How many amps will 4 gauge wire handle?
The amps that a four gauge wire will handle will depend with the thickness of the wire. If the wire is thin, the four gauge will handle 95 amps.
How many amps will a 4 gauge aluminum wire carry?
A 4-gauge aluminum wire can typically carry up to 70-85 amps of current for general household wiring applications. It is important to always consult with local electrical codes and a professional electrician to ensure safe and compliant electrical installations.
How many amps can 16 gauge wire carry at 120 vac at 25 feet?
A 16 gauge wire can typically carry around 10-13 amps at 120V AC over a short distance like 25 feet. It's important to follow standard safety practices and consult with an electrician to ensure that the wire gauge is appropriate for your specific application and local electrical code requirements.
How many automotive amps can 30 foot strand of copper wire carry?
The number of automotive amps a 30-foot strand of copper wire can carry depends on the gauge (thickness) of the wire. For example, a 30-foot strand of 10-gauge copper wire can typically carry up to 40-50 amps for automotive use, while a 30-foot strand of 12-gauge wire might be limited to around 25-30 amps. It's important to consult wire ampacity tables and consider factors like temperature and voltage drop to ensure safe and effective performance.
What gauge wire is needed for 7.5 amps?
AWG # 14 is the smallest wire you can install in a home and it can only be used in living areas. It will carry 15 amps.
How many amps will 200ft of 6ga wire carry?
50 amps.
How many amps will 10-2 wire carry at 40 feett?
30 amps is how much a 10-2 wire will carry at 110 feet. 10 gauge wire is only good for thirty amps per the national electrical code. Using 80% of the breakers usage you will actually be getting only 24 amps.
What wire gauge is needed to carry 150 amps at 240 volts?
At the service entrance you will need AWG 1/0 gauge.
How many amps for 14 wire how many amps for 12 wire?
A 14-gauge wire can typically carry up to 15 amps of current, while a 12-gauge wire can handle up to 20 amps. It's important to follow the manufacturer's guidelines and electrical codes when determining the maximum current for a specific wire size.
How many amps can a 6 gauge wire hold?
101 amps for chassis wiring and 37 amps for power transmission. This is for short lengths of wire.
