What Size Wire For 100 Amp Service 250 Feet

Stuck on what wire size for 100 amp sub console to use? Does a 100 amp sub panel wire size stand for to a 100 amp wire? Or have you ever wondered what wire size for 100 amp service or what size wire practice I need for a 100 amp sub panel?

Desire to know the brusk answer? A 100 amp sub panel wiring size requirement is #4 for copper wires and #2 for aluminum wires. Now, you lot may question what y'all should use for your wiring installation and what are the advantages and disadvantages of ane wire type from another. Nosotros'll discuss these problems below.

Wire Sizes

Wiring size requirements differ per amp rating of the circuit. For example, you may utilise a 10 AWG or American Wire Guess for a thirty amp appliance, and a size 8 AWG for a 45 amp device. The size of wire you will utilise will differ as well depending on what particular electrical installation or servicing you will be doing.

Earlier reading wire sizes, information technology is of import to know the basic technicalities of electrical installations. Many newbies or students without feel or advanced noesis may miss these easily and cause serious damages to appliances and or components.

American Wire Gauge is the standard when measuring wire sizes. Gauge but describes the thickness of the wire through numbers. The smaller the number, the thicker the wire volition be and vice versa.

By that, we can say that the thicker the wire, the more than amperage a wire can support and deliver. Knowing this aspect or property of wire tin can relieve you or your appliances from electrical damage, specially brusque circuits or even fire.

Choosing the Right Wire

Depending on your preference, you may choose wires that you recall volition suit your project with respect to condom and fire hazard. Virtually manufacturers put labels on wire coatings or insulation indicating the material's type and gauge.

Nearly houses employ copper wires for wiring installations, including sub-panels and other electrical components. Bigger infrastructures, including electrical posts, use aluminum wires instead of copper.

Bated from fire safety, infrastructure owners likewise take into consideration the economic attribute when choosing the right blazon of materials for their wiring organization.

Due to abundance, the use of aluminum wire, although less conductive, is widely accepted considering it offers a cheaper price, unlike copper wire. Sacrificing a petty bit of efficiency for the purpose of economic gain may exist a tough phone call but a worthy shot.

For the purpose of comparison, here are the characteristics of copper and aluminum wires. This may aid you decide what to choose for your sub-console installation and also provide additional information that you may use for hereafter electrical servicing.

Copper Wire

Copper wires are extensively used in modern houses and infrastructures due to the wire's swell conductibility and stability. Its stability and effectiveness in conducting electricity cannot be closely compared to aluminum wires or any other material, giving copper the best output when talking nearly efficiency in power, next to silverish.

Silverish wire is a meliorate choice in conductivity than copper, only it is not widely used in houses and other buildings or infrastructures due to its disadvantages in other properties, such as a lower melting signal compared to copper and a higher cost than whatsoever other usual conductors we are using.

Although silver is non that viable in homes, its use was widely accepted when information technology comes to technology. Special wirings and critical components are loaded with silvery wires because of the material's loftier conductive holding.

Another factor why you should consider choosing copper wire instead of aluminum wire is that copper wire possesses loftier tensile strength — pregnant it has much higher resistance and protection against breakage. It besides expands less at high temperatures compared to aluminum.

One drawback of choosing copper wire instead of aluminum wire is that copper wire somehow is heavier than aluminum when using the same volume. Copper wire is also costlier than aluminum wires, giving it a prominent disadvantage economically.

Aluminum Wire

If yous decided to use aluminum wire for your 100 amp sub panel, you should therefore use #2 aluminum wires to avert malfunctions such as brusque circuits that may crusade electrical damage to your components.

Aluminum wires are way cheaper than copper wires because of the textile's abundance and disadvantages compared to copper wires. It is besides lightweight, making it much lighter compared to copper.

Looking on the negative side, aluminum wires are inefficient in conducting electricity. It is also malleable but not ductile, and decumbent to galvanic corrosion because it oxidizes faster than copper. All these aspects, amidst others, make aluminum less desirable in residential buildings.

Electric malfunctions come afterward human errors and from the usage of inappropriate wire sizes, materials, and substandard components. Moreover, opting for safer and more efficient materials volition significantly contribute to risk reduction and mitigation.

Fire Safe

If y'all are planning on installing or fixing sub-panels and came across a decision where you have to choose whether to use copper or aluminum wires, these are the things you should consider.

• Copper is generally safer to employ in electrical installations such as sub-panels because compared to aluminum, copper does non expand easily similar aluminum wires when current runs through the wires.
• The conductive belongings of copper makes information technology efficient in transmitting power or current from i end to another. Hence, the manual does not crave much energy that can be lost in the process or transformed into a different form of free energy such as heat that may lead to a fire.
• Materials you purchase, may information technology be copper or aluminum wire, should pass the standard set forth by your authorities. This will give you plenty confidence that y'all are beginning your project on the right path.

Considering all condom precautions, it is also all-time to know what y'all are really doing and the things y'all are almost to deal with. Aside from fire safe, your physiological safety should be the summit priority. In other words, before doing any electrical installations, you should be circumspect to things like:

• If you are non set to do it, do not force yourself to do information technology.
• Equip yourself with more than knowledge earlier engaging in these kinds of jobs.
• Gain experience and guidance from experienced individuals regarding the servicing you are about to do.
• Call a professional electrician to do the job for you.

Conclusion

Hopefully, you can now answer the question "what size wire do I need for a 100 amp sub panel?"

Aside from that knowledge, know what precautions to have when installing or servicing your sub-panels or any other type of electrical components.

If you happen to be afraid of risking electrical damages, keep in heed:

• If you are not ready to practice it, do non forcefulness yourself to exercise it.
• Equip yourself with more than knowledge before engaging in these kinds of jobs.
• Gain experience and guidance from experienced individuals regarding the servicing you are about to practice.
• Phone call a professional person electrician to do the job for yous.
