JudyFor a 12VDC system with 30 amps, you would typically use a wire size of at least 8 AWG (American Wire Gauge) to ensure it can handle the current without overheating. It's always a good idea to consult a wire ampacity chart to select the appropriate wire size based on the length of the wire run and the specific conditions of your setup.

What size wire for a 30 amp breaker to ac?
A # 10 wire with a insulation factor of 75 or 90 degrees C are both rated at 30 amps.
What size of wire needed for 220volt?
The size of wire needed for a 220v circuit depends on the amperage of the circuit. For a typical 220v circuit at residential settings, a 10-gauge wire size is commonly used for 30 amps, while larger circuits may require 8 or 6-gauge wire for higher amperage ratings. It is important to consult with a licensed electrician to ensure the correct wire size is used for your specific application.
What size wire and breaker do you need for a 5000 watt garage heater?
Look on the heater and see what amps it is pulling. That will determine the wire size and breaker size. It must be on a dedicated circuit. 15 amps = AWG # 14 wire with 15 amp breaker 20 amps = AWG # 12 wire with 20 amp breaker 30 amps = AWG # 10 wire with 30 amp breaker 40 amps = AWG # 8 wire with 40 amp breaker
What size wire should I use for a 50' 30 amp 240 volt line?
For the short distance of 50 feet no voltage drop calculations are needed. A #10 copper conductor with a insulation factor of 60, 75 or 90 degrees C is rated at 30 amps respectively. This conductor can legally be loaded to 80% capacity. This allows 30 x .8 = 24 amps. If the device draws more that 24 amps then go to the next wire size which is a #8. A #8 copper conductor with an insulation factor of 75 and 90 degrees C is rated at 45 amps respectively. This legally allows 45 x .8 = 36 amps to flow on the wire. Of course with this size wire only 30 amps will be allow to flow before the breaker will trip.
How many amps will 10 wire hold?
A 10-gauge wire can typically handle around 30-35 amps of current. It is important to consult the National Electric Code and wire manufacturer specifications to determine the maximum current carrying capacity of a specific wire in a given installation.
