There is a formula based on wire type, length, and current. The easiest way nowadays is to use an online calculator. Remember when using that calculator that both wires in the circuit count (hot & neutral), so don't divide the length by 2. Just enter the length of your run.

How do you tell what gauge wire you have in your house?

To determine the gauge of wire in your house, look for markings on the insulation or jacket of the wire. It usually indicates the gauge size, such as 14, 12, or 10. You can also use a wire gauge measuring tool to accurately determine the wire gauge.


What gauge is use on low votage?

For low voltage wiring, typically smaller gauge wire is used, such as 18 or 20 gauge. The specific gauge will depend on the current requirements of the circuit and the distance the wire needs to run. It's important to consult the manufacturer's recommendations or local building codes to determine the appropriate wire gauge for your application.


What gauge wire should be used to run a 230v motor 90 ft away?

For a 230V motor running 90ft away, it is recommended to use at least 12-gauge wire to minimize voltage drop and ensure efficient operation. However, it is always best to consult the motor's specifications and a qualified electrician to determine the most appropriate wire gauge for your specific setup.


Can you use 10 gauge wire to connect a 2 15 amp outlets to a 30 amp breaker?

No, it is not safe to use 10 gauge wire with a 30 amp breaker as the wire is not rated for that high of a current. It is important to use the correct wire gauge that matches the breaker amperage to prevent overheating and potential fire hazards. For a 30 amp breaker, you should use at least 10 gauge wire.


What size wire and breaker for a 7.5 hp motor?

For a 7.5 hp motor operating at 240V, you would typically use a 14-gauge wire and a 40 amp breaker. However, it is best to consult the motor's specifications and the National Electrical Code to determine the exact wire size and breaker needed for your specific setup.

A method to work out the thickness of a wire?

You can use a micrometer to measure the diameter of the wire. You can also consult the wire's datasheet or product specifications for information on its thickness. Another option is to use a wire gauge tool to determine the wire's thickness based on its gauge number.

What size wire do you use on a fridge freezer?

12 gauge wire is used for household plugins, and 14 gauge wire is used for lights. So, 12 gauge is the size to use. But since a freezer has an electric motor, it is best to not plug anything else with a motor into the same circuit.


What is the recommended gauge for electrical wire to use in a residential setting, specifically when considering the use of 18 gauge electrical wire?

The recommended gauge for electrical wire in a residential setting is typically 14 or 12 gauge wire. 18 gauge wire is generally not recommended for household use as it may not be able to handle the electrical load safely.


What is a wire gauge and what is it's use?

wire gauge is used to determine the size of the wire to be installed based on the amperage draw of whatever is being hooked up on the receiving end. ie 14 gauge is for a 15 amp circuit, 12 gauge is for a 20 amp circuit, 10 gauge 30 amp etc. to get specific amp draw ratings on a particular gauge of wire look at a current National Electric code book or ugly book.
