Aluminum has a lower conductivity than copper. Copper, however, comes at a higher price.

Aluminum is lightweight and flexible, making information technology easier to work with. Both have singled-out characteristics, but you must cull the best suits your requirements.

We recommend either 2/0 AWG copper wire or 4/0 AWG aluminum wire for single-phase.

Yous can employ 1/0 AWG Copper wire or iii/0 AWG Aluminum wire for a three-stage power source.

Source Voltage

Keep the source voltage in mind when expanding your electric circuit. Household and industrial source voltages may differ from one location to the side by side.

In the U.s.a. and Canada, the standard source voltage is 120V. Withal, industries may use a unlike source voltage.

Number of Phases

When you hear the word 'phases' in relation to electricity, you might exist perplexed. However, it's a relatively unproblematic term to grasp. The load distribution is referred to past the number of phases in electricity.

There are ii common types of phases: unmarried-phase and three-stage.

Three wires are required for a single-phase excursion, and a iii-phase circuit, on the other mitt, requires four, with one being a ground wire.

Examine the number of wires to figure out which phase y'all're on.

In most homes, single-phase power is used, but 3-phase ability is used in factories. This is because a iii-phase circuit ameliorate accommodates college loads. (Read Metric Socket Sizes)

Voltage Drop

This may exist a scrap of a geeky concept for you to grasp. It is, yet, disquisitional information that y'all should be aware of.

The electrical channel will have some resistance when connecting a afar location to the source via conductors. The source voltage would pass up as a outcome of this. Even when using a junction box to extend the wire.

The source voltage reduces slightly as the line lengthens.

A voltage dip of 1 to 5% is usually acceptable (3 percentage is calculated every bit optimal). Ensure, however, that the voltage loss does not exceed five% in any way.

A voltmeter could be used to measure the voltage decrease. Still, it's best to get a professional person to do this for yous because the wires are and then long.

In that scenario, option your wire carefully. The voltage drop would exist significant if the wire diameter were insufficient to handle the load.

Installation Method

Depending on the installation method y'all're choosing, the wire size may vary. This may influence the resistance encountered by your circuit.

Typically, in that location are a few standard installation methods. The installations can exist installed in a raceway (conduit or tray), cached in the footing, in a cable, or fifty-fifty on the open ground.

The approaches differ depending on the wire yous're working with. Consult a professional person for communication on how to wire your dwelling house. Excessive overheating from too much electrical current tin can cause an electrical fire when many electric appliances are running simultaneously. (Read Wagon Bolt Sizes Chart)

Can I Use Oversized Wires?

If you're preparing for time to come secret wiring expansions, you can use bigger wires than the correct judge wire. This shows that the wire's diameter is larger than you crave for your main ability panel.

In terms of the existing growth programme, this volition not be a deal-breaker. If you kept the rest of the things in perfect order, you have a excursion billow to match the supply voltage.

There should exist no noticeable differences in the performance of your circuit. The only reward you lot may experience is a reduction in voltage loss. In the first place, anything less than five% is acceptable.

What If I Utilize Undersized Wires?

You lot can current of air up with bad news if you lot employ cables that are smaller than required—burning all of your electronics, besides equally your mainline 100 amp sub panel, and possibly your habitation or business. Even one faulty outlet tin can wreak havoc on the others.

When you lot apply smaller wires, the wires are exposed to more resistance. This can lead to a lot of heat and the potential to melt the wire insulation on your electrical wires.

What Size Wire Practice I Demand to Comport 100 Amps 100 Feet?

Conductors of iii AWG copper or 1 AWG aluminum would be required for a 100 amp excursion.

For a 20 amp circuit, what gauge wire is required? A twenty-amp circuit must exist fed by 12-gauge or 10-gauge wire, protected by a 20-amp breaker or fuse.

What estimate wire do I need for a 100 amp service to a workshop over 100 feet? Conductors for a 100 amp excursion are likely to be three AWG copper gauge wire or i AWG aluminum estimate wire.

Is there a limit to the amount of current that electric wiring can carry? Each wire size, also known every bit a guess (AWG), has a maximum current limit to withstand earlier condign damaged.

It'due south critical to choose the right wire size not to overheat. Because the current that flows through the wire is usually adamant past the number of devices continued to the circuit.

What Size Wire Is Needed For A 100 Amp Residential Service?

A regular firm service uses how many amps?

Electric service of at least 100 amps is required in near homes. The National Electrical Code specifies this equally the minimum panel amperage (NEC). A 100-amp service console should be plenty to power a medium-sized domicile with many 240-volt appliances and central air conditioning.

The wire gauge of the cablevision must friction match the amperage of the subpanel—for example, a 100-amp subpanel requires #iv copper wires or, more oftentimes, #2 aluminum wires. (Aluminum feeder cables are often utilized since they are less expensive than copper wires.)

For a 200 amp residential service, what size wire do you lot need?
