wire size

100-amp-wire-size-calculator

Conductor size requirements vary depending on circuit amperage. For example, you can use 10 AWG or American Wire Gauge for 30 amp equipment and size 8 AWG for 45 amp equipment. The size of wire you use will also vary depending on the specific installation or electrical maintenance you will be performing.

Before reading wire sizes, it is important to know basic electrical installation techniques. Many beginners or students without advanced experience or knowledge can easily miss them and cause serious damage to devices and/or components.

American Wire Gauge is the standard for wire sizing. Gauges simply describe thread thickness through numbers. The smaller the number, the thicker the thread and vice versa.

Therefore, we can say that the thicker the wire, the more amperage a wire can hold and deliver. Knowing this aspect or characteristic of conductors can prevent you or your devices from electrical damage, including a short circuit or even a fire.

Choose the right thread

Depending on your preferences, you can choose the wire that you think will suit your project in terms of safety and fire risk. Most manufacturers place a label on the coating or insulation of the wire indicating the type and gauge of the material.

Most homes use copper wire to install electrical wiring, including side panels and other electrical components. Large installations, including utility poles, use aluminum wire instead of copper wire.

In addition to fire safety, infrastructure owners also consider economics when choosing the right materials for their electrical wiring.

Due to its abundance, the use of aluminum wire, although less conductive, is widely accepted as it offers a cheaper cost, unlike copper wire. Sacrificing a little efficiency for savings can be a tough decision, but a well-deserved boost.

For comparison, here are the characteristics of copper wire and aluminum wire. This can help you decide what to choose to install the sub-panel and also provides additional information that you can use for future electrical maintenance.

The copper

wire-size-for-100-amp-sub-panel

Copper wire is widely used in modern homes and infrastructure due to its high conductivity and stability. Its stability and conductive efficiency cannot be matched by aluminum wire or any other material, which gives copper the best score in electrical efficiency, next to silver.

Silver wire is a better choice in terms of conductivity than copper, but it is not widely used in homes and buildings or other infrastructure due to its disadvantages in other properties, such as lower melting point than copper and higher cost than any other current. to note. driver we use.

Although cash is not viable in households, its use has become widely accepted in technology. Special conductors and critical components are loaded with silver wire due to the material’s high conductive properties.

Another factor why you should consider choosing copper wire over aluminum wire is that copper wire has a high tensile strength, which means it has resistance and protection against much higher breakage. It also expands less at high temperatures than aluminum.

A limitation of choosing copper wire over aluminum wire is that copper wire is somewhat heavier than aluminum when using the same mass. Copper wire is also more expensive than aluminum wire, resulting in a significant economic disadvantage.

aluminum wire

100-amp-wire

If you decide to use aluminum wire for your 100 amp sub-panel then you should use

Aluminum wire is cheaper than copper wire due to the abundance of materials and disadvantages compared to copper wire. It is also lightweight so much lighter than copper.

On the negative side, aluminum wire conducts electricity less efficiently. It is also ductile but not ductile and is susceptible to galvanic corrosion as it oxidizes faster than copper. All of these aspects, among others, make aluminum less desirable in residential buildings.

Electrical failures are caused by human error and the use of improper wire gauges, materials, and substandard components. Additionally, the selection of safer and more effective materials will contribute significantly to the reduction and reduction of risk.

fire safety

wire-size-for-100-amp-sub-panel-100-feet-away

If you are planning to install or repair subpanels and decide to use copper or aluminum wire, here are the things to consider.

  • Copper is generally safer to use in electrical equipment such as side panels because, compared to aluminum, copper does not expand as easily as aluminum wire when current flows through the conductor.
  • The conductive properties of copper make it efficient in transferring electricity or current from one end to the other. Therefore, the transmission process does not require a lot of energy which can be lost in this process or converted into another form of energy such as heat which can cause a fire.
  • The material you purchase, whether copper wire or aluminum wire, must meet the standards set by your authority. This will give you enough confidence that you are starting your project on the right track.

Considering all safety precautions is also the best way to know what you are really doing and what you are about to tackle. In addition to fire safety, your physiological safety must come first. In other words, before carrying out electrical installation work, you should pay attention to such things as:

  • If you’re not ready to do it, don’t force yourself to do it.
  • Arm yourself with knowledge before embarking on jobs like this.
  • Gain experience and advice from experienced people about the service you are about to perform.
  • Hire a professional electrician to do the job for you.

Conclusion

I hope you can now answer the question “what size wire do I need for a 100 amp subpanel?”

Beyond this knowledge, know what precautions to take when installing or servicing your subpanels or any other type of electrical component.

If you are concerned about electrical hazards, keep in mind:

  • If you’re not ready to do it, don’t force yourself to do it.
  • Arm yourself with knowledge before embarking on jobs like this.
  • Gain experience and advice from experienced people about the service you are about to perform.

Popular questions about what size wire to use for 100 amp service

what size wire to use for 100 amp service?

For 100 AMP service, you’ll need a #4 AWG copper wire or #2 AWG aluminum or copper-clad wire. Make sure to limit your voltage drop to 3% regardless of distance.

What wire do I use for a 100 amp sub panel?

The cable must have a wire gauge sufficient to the amperage of the subpanel—a 100-amp subpanel requires #4 copper wires or, more commonly, #2 aluminum wires, for example. (Aluminum is often used for feeder cables because the cost is typically much lower than that of copper wires.)

What size conduit and wire do you use on a 100 amp service?

A 100 amp service will need a minimum of 1.25 inches, schedule 40 or 80 PVC grey electric conduit. You can use a larger conduit if necessary to maintain the inner fill of 40% or less. A 1.5 or 2-inch conduit is best if running three or more electrical wires within the same electric conduit.

Today we are running a 100 amp service wire from the house to The work shop. We will wire it into the main panel in the house and also into the main panel in the work shop.

This is not a tutorial, I’m just showing what we did. .

I’m not an electrician, we are just doing this for our own self. We followed instructions from the builder supply that we purchased all of the materials from. We were told that a 3 wire install was ok as long as we grounded it at the sub panel. I checked a shop across the road from me and it was wired with 3 wires also. I did the install just like the shop across the road that was wired by a licensed electrician several years ago. I have learned recently that the new code requires 4 wires. The 3 wire system will work but does not meet code. We are going to go back and run an extra wire to make it meet the current code. If you are doing this check with your local electrical codes for more info. I hope that this info will help to clarify what I did. Calvin
