How do you determine which wire is the 'feed' wire?
Check it with a voltmeter or with a voltage detector.
How big is 6 gauge wire?
The size of the wire is stated by its gauge under American Wire Gauge. Six gauge wire is size 6 AWG.
What size wire is required for 277 volt fluorescent lighting?
Wire size is governed by amperage not voltage. Voltage is an insulation factor when talking about wire. Add up the amperage of fixtures you want in the circuit. Once that is found then the size of the wire can be calculated.
What size wire to use to install a thermostat?
Use what is called bell wire or thermostat wire.
What is the minimum wire size used in a commercial building?
The minimum size wire that engineers spec for industrial and commercial installations is #12 and it usually is stranded not solid wire.
How do you determine the proper fusing of a circuit?
Fusing is based on wire size and demand load.
What gauge wire do you need for 12 volts at 4.2 amps in my car for a light H11 Light bulb?
Almost any size wire will handle the 4.2 amps. BUT...as with any wiring, you must look at the over current device to determine the proper size. You need to determine which fuse in the fuse panel protects that circuit and use a wire that is appropriate for that size fuse.
What is the use of wire gauge?
Wire gauge is used to determine the size wire needed to carry the correct amount of current for the job. It must be sized appropriately for the current in the circuit you are building.
What is a messenger wire?
A messenger wire is a wire or cable that is used solely for the physical support of another element, typically a conductive wire or bundle of wires. The messenger wire will take the shape of a parabola (shape of a free hanging string) and the conductive wore or bundle of wires supported by the messenger may follow that parabola of be supported in a straight lines through the use of drop lines. Take a look at the power catenary for a light rail or electrified bus system.
What is the designation mmca for wire as in 500 mmca stand for?
The term "mmca" typically stands for "messenger/messenger covered aluminum" in the context of electrical wires. So, in the designation "500 mmca," the wire is likely a messenger wire with a covered aluminum conductor that can be used for supporting and transmitting electricity.
What cable wire size for 1000 watts aircondition?
The only way to determine the cable wire size needed for a 1000 watt air conditioner is to find the load size. To get the load size you will need to use the formula Amps = Watts or Volts. With that being said, you will need a number 14 copper wire.
What size wire is needed for a 180' run?
The wire size needed for a 180' run depends on the voltage, current, and type of installation. It is recommended to consult the National Electrical Code (NEC) and a professional electrician to determine the appropriate wire size to ensure safety and compliance with regulations.
How do you determine the equipment ground wire size for equipment?
It is an electrical code rule that is determined by the amount of current that a connected device draws. Depending on the amperage that the equipment will draw determines what the size of the wire needed to handle the fault current. The larger the amperage the larger the ground wire needed.
What size wire for 28 amps?
For 28 amps, you would typically use a wire size of at least 10 AWG (American Wire Gauge) for copper wire. This would ensure that the wire can safely carry the current without overheating. It's always a good idea to consult a professional electrician or refer to local electrical codes to determine the appropriate wire size for your specific application.
How do you determine wire size for Power circuits based on distance?
There are engineering book that tells you depends on a lot of things type. temp and then some.
What is more important for amperage rating wire size or insulation temperature rating?
Both wire size and insulation temperature rating are important for determining the amperage rating of a wire. The wire size helps to determine how much current the wire can carry without overheating, while the insulation temperature rating ensures that the wire can handle the temperature generated by the current passing through it. Both factors work together to determine the overall amperage rating of the 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.
