The messenger in triplex and quad is already determined by the wire size that is wrapped around it. It is the maximum span distance that you should find for the size of over head cable that is being used.

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 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.
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 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
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.
Explain wire size as opposed to gauge size?
see American Wire Gauge. The larger the number the small the wire size.
How do you determine which wire is the 'feed' wire?
Check it with a voltmeter or with a voltage detector.
What size wire do i need to feed a single phase V primary and a V secondary fed from a 150 amp circuit breaker?
Information is incomplete. You need to know the load in Watt or Kilowatt and the voltage on the secondary side to determine the load current, on which the size of the wire is designed.
How do you calculate the voltage drop for 238 KW 3 phase 415 V and length of circuit is 20 meters?
You need also to know the resistance of the cable. First you establish what the current of the load is. Then from that you calculate the wire size. From a wire size chart you find the wire resistance. Then use the formula I (squared) x R.
