## How do I know what size feeder wire to use?

Determine the minimum feeder conductor size, before you apply any conductor adjustment and/or correction factors, by adding the two following quantities: 125% of the continuous load [215.2] and 100% of the noncontinuous load.

## Where is the 83% rule in the NEC?

Most of us are aware by now that in the 2014 NEC, Table 310.15(B)(7) has been removed and replaced with a simple percentage (83%), which when properly applied to the rating of the service, will result in the same size service or feeder conductors that were previously listed in the deleted table.

## How do you size a feeder NEC?

Quote from the video:
Quote from Youtube video: Basic rule is you size the feeder conductor sizing at 125. Percent of the continuous load plus the non continuous load will change theorists we've always done.

## What is a feeder wire?

Feeder cables are used to supply power from one part of a facility to another, from point A to point B. Perfect for providing temporary power service during construction or to supply power to specialized equipment. Primary feeder cables typically run between main switchboards and power distribution transformers.

## What is the minimum size of service entrance conductor?

Based on your load, this minimum size would be 60A according to Section 230-79(d). Although you would be permitted to have conductors, a main disconnect, and an overcurrent device as small as 60A, 230-91 requires the overcurrent device to provide overload protection for the service conductors.

## What gauge wire does the service entrance of a residence required?

This is the minimum required service conductor. Take 83 amps and use the 75°C column in Table 310.15(B)(16) to determine that the service requires 4 AWG copper, type THWN overhead service entrance conductors.

## What is difference between a feeder and transmission line?

Transmission lines are current carrying lines that carry power from generating stations to the substations. Feeder is an electrical distribution network. They carry power from substation to consumers . A feeder is line which starts from grid to whom which we want to transmit power to the consumers.

## What is a feeder in electricity?

Feeders are used for the transmission of electricity it is the power line in which electricity is transmitted in power systems. It does the transmission of power from the generating station or substation to the distribution points.

## Can you run branch circuits with feeders?

“You can’t use a panel as a raceway!” “You can’t run branch circuits and feeders together!”

## What size wire do I need for 100 amp service?

Size Wire for 100 Amp Service

Wiring a 100 amp breaker panel requires either #4 copper wiring or #2 aluminum or copper-clad wiring.

## What size wire do I need for 200 amp service?

The Short Answer: Like with aluminum, you’ll need a #4/0 copper-clad aluminum wire for a 200 amp service.

## What size wire will a 100 amp breaker accept?

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 need for a 100 amp subpanel?

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.)

## Can a 60 amp breaker feed a 100 amp sub panel?

You can feed a 100 Amp panel with a 60 Amp breaker. Keep in mind that the sub panel needs to be rated above the breaker size.

## What wire size do I need to go 100 feet for a 100 amp service to a workshop?

For a 100 ampere circuit, the conductors will likely be required to be 3 AWG copper or 1 AWG aluminum.

## Can you run a 100 amp sub panel off a 100 amp main panel?

Let me try and answer some of your questions. First the panels you are looking at that are rated 100A simply means you can use them for any application up to 100A. You can for example add a 60A breaker to your existing panel and protect the new subpanel with a 100A rating.

## What wire size do I need to go 200 feet for a 60 amp service to a workshop?

60 amp wire size is either 6 AWG or 4 AWG wire (AWG stands for American Wire Gauge; standard wire sizing is the US) for 220V voltage. An amateur will use a 6 AWG wire size for 60 amp 220V. A professional will always use 4 AWG wire size for 60 amp 220V.
