When the power goes out in your house, you’ll need a generator to keep the lights on at the very least.

However, certain appliances, such as the refrigerator or the washing machine, may need constant operation.

Back feeding is a word used in this situation.

So, what exactly is it and how does it function?

Backfeeding is the flow of electric electricity in the opposite direction of what is often anticipated or expected.

Depending on the source of electricity, this reverse flow might be deliberate or unintended.

If backfeeding is not prevented (in the case of unintended backfeeding) or performed appropriately, it may cause unforeseen issues for electrical grid equipment and service people (in the case of intentional back feeding).

In the case of a power loss, you may power your home by backfeeding with a generator.

A backfeed wire hooked into a 240-volt outlet links an outside generator to your house.

Backfeeding is safe when done appropriately (with a bypass switch).

Attempting to backfeed without a transfer switch might allow electric power to flow backwards through the utility service, causing grid damage or, worse, killing a lineman attempting to restore electricity.

This page covers a variety of topics related to backfeeding, including how it works and the serious consequences of using this practice.

After all, working on anything that involves electricity, particularly in a DIY situation, may be dangerous.

If that’s the case, continue reading to learn all there is to know about backfeeding!

What Is The Purpose Of A Breaker Panel?

To begin, it is necessary to understand what a breaker panel is in order to learn more.

Simply explained, a breaker panel is the device that manages all of the energy in your house.

It is made up of many wires on a board that distributes power throughout the house.

The panel also features a fuse protector for each circuit within a certain area, which means that if you consume too much electricity, a section of your house will go out, requiring you to walk down to the panel to reset the circuit breaker.

Although a breaker panel is often referred to by that name, many alternative names are considered, therefore the term does not have a one-size-fits-all definition.

The following are the words:

  • Panel of electricity
  • Panelboard
  • Board of distribution
  • DB table
  • Box DB

In terms of how a breaker box operates in the United States, it has two columns on each side.

From top to bottom, the numerals go from left to right.

In general, the numbering system is uniform across a wide range of brands.

Instead of two columns, some electric panels use an A, B, and C for the rows, enabling two or three trip breakers.

Each phase will get a pole in exchange.

In North America, there will always be a wire running from line to line for huge equipment that takes up 2-pole or 3-slots in the panel.

Each split-phase electric power utilizes 240 voltages, and the panel uses 3-phase power and 208 voltage.

Backfeeding An Electrical Panel With A Generator Is What It Sounds Like.

TO BACK FEED OR NOT TO BACK FEED? Powering your house with a generator. – TOOLMAN TIM’S WORKSHOP

As you may be aware, when electricity enters your house, it powers all of your appliances, lights your home, and allows you to use the outlets as a power source to charge anything you want (phones, TVs, tablets, etc.)

Backfeeding occurs when energy from a generator flows back into the power system, causing damage to the grid or the death of linesmen working on power outages.

A backfeed wire linked to a 240-volt external outlet links a generator to the home.

A transfer switch, which cuts off the power flow to the meter base and out to the power grid, is required to avoid backfeeding.

Without a transfer switch, the electric power generated by the generator flows via the main breaker, back to the meter base panel, to the transformer, and then to your neighborhood’s utility lines.

A transfer switch is required to circumvent the meter base and avoid backfeeding the public grid.

Before installing a generator, it’s advisable to have a certified electrician install a transfer switch.

When individuals backfeed their houses, they build a backfeed wire with two male plugs linked to the generator, as seen in the video above.

The branch circuit breaker of the outlet feeds electricity into the main breaker.

If you’ve ever removed an extension cable end, this should be quite simple.

The cables, on the other hand, are significantly bigger and more difficult to deal with.

Make careful you strip them down as normal, then disassemble the male end of the plug and join the wires.

Check that the red and black cords are on opposite sides, the ground is at the top, and the white is at the bottom.

Note: If you’re not sure what you’re doing with plugs, don’t.

It is preferable to be safe than than sorry.

What Are The Dangers Of Back Feeding?

When dealing with anything electrical, it is critical to understand what you are getting yourself into.

#1. You Don’t Have Enough Experience.

Many individuals attempt to undertake things themselves, such as electrical work or renovations that need a permit, in their houses.

Although certain DIY projects, such as furniture manufacturing or other jobs, are fair, others should be left to the pros.

In this instance, hiring a professional to assist you with properly installing the generator connections is the best way to guarantee that everything is done correctly.

#2. It’s Illegal In A Lot Of Places.

Not only is it not for novice individuals, but back feeding is illegal in many states, nations, and communities when it comes to dealing with utility lines and electrifying them to achieve what you want.

If you’re unclear about the laws in your location, do some research.

It is prohibited because it has the potential to result in death, injury, or property damage.

Backfeeding may also pose a serious hazard to utility personnel who operate on the line all year.

It is a liability concern if they are harmed or killed as a result of your back feeding, and you may face criminal charges.

Assume your Internet goes down, which is more often in certain locations than others.

In such situation, someone working on the wire might be seriously wounded as a result of the energy flowing through the neighborhood’s utility lines.

#3. Disconnection of Fines Charged Power

Furthermore, avoiding harming someone has its own set of repercussions.

Multiple penalties may be imposed, or your home’s electricity may be disconnected by the utility provider.

Keep in mind that 240 volts of electricity may instantaneously kill someone.

It’s not a matter of whether you can do it; rather, it’s a question of whether you’re ready to put yourself and others in danger for something you might simply avoid.

You must turn off the primary breaker if you want to lessen the chances of this occurring.

However, it is critical to understand that there is no 100% assurance against any risks.

#4. Inadvertently Tripping On The Backfeed Cable

To get to our next point, if someone were to slip or fall over the backfeed cable, it may come free, resulting in electrocution.

The breaker back feed cable is sometimes referred to as a “suicide cord.”

Let’s say you live with an elderly person, have little children, or maybe have a few animal companions.

This may be a huge danger issue if it’s dark or someone isn’t paying attention.

#5. Inability to Balance the Loads

Finally, the electric panel receives power from the generator, which supplies power to the whole house while backfeeding.

However, the power of a big portable generator is limited.

Running too many circuits may result in a considerable voltage loss, causing the loads to become unbalanced.

Given such information, a generator may send 240 volts of electricity over two 120-volt lines, delivering half of the generator’s capacity on each line.

The load grows increasingly imbalanced as you perform more circuits.

Why Do People Backfeed When It’s Against The Law?

Why do individuals continue to back feed despite the fact that it is now prohibited in many places? What is the aim of this?

People backfeed because it injects energy into power outlets during a blackout, allowing them to utilize their appliances.

For example, if there is a major storm in the neighborhood and everyone loses power just after you go food shopping, those perishable things are in danger.

Another reason to backfeed is so you can finish cooking your meal or do the laundry you’ve been putting off for a week.

Some Back-Feeding Solutions

Not everyone will want to back feed their houses since they don’t want to jeopardize their own or others’ safety inside or around them.

In such situation, there are a few options available to you.

#1. Solution for the Washing Machine

You may get a manual washing machine, such as this one, that is really straightforward to operate when it comes to washing your clothing.

Not only is it a good idea to have a generator on hand in case of an emergency, but a manual washing machine may also be used in RVs, camping, tiny flats, and dorm rooms.

Air-drying your items once the cycle is finished may be the best option.

#2. Cooking Option

A camping stove within your house is a wonderful alternative for cooking since it eliminates the need for power.

#3. Refrigerator

Perishable things are a bit more difficult to transport.

Unless you have a large container of dry ice on hand, the best alternative may be to avoid opening the fridge or to store chilled products in a large freezer until the power is restored.

What Is the Difference Between Backfeeding and Breastfeeding?

There are many distinct sorts of backfeeding to be aware of.

These are the following:

  • Intentional
  • Unintentional
  • Intrinsic

#1. Backfeeding on Purpose

Many commercial items have finally found their way to those who want to buy them for their homes in the past few years.

Wind turbines and solar panels are excellent instances of commercial product demand.

Generated electrical power is no exception in this instance.

A generator is necessary when the power generation conditions are ideal.

The power grid systems are supplied with electrical power if the electric utility supplier is unable to sustain greater power production.

The amount of energy you’ve used is shown on a utility meter.

The power generator is utilized for a short period due to backfeeding, and electricity remains in reverse mode as long as the generator is active.

#2. Inadvertent Back Feeding

Many homeowners or customers are unaware that they are backfeeding, which is often accidental.

It usually occurs when the portable generator is in operation and is plugged in improperly.

When there is a power outage and a homeowner wants to use their appliances, energy travels in the other way across the electrical power lines, re-energizing them.

However, directly putting the generator into an appliance outlet in their dwellings might be problematic.

Despite the fact that your appliances are turned on, energy flows back into the power lines, putting you at danger.

#3. Intrinsic Backfeeding

Finally, intrinsic back feeding will be discussed, in which the generator does not output more electrical power than it can manage.

The consumer then becomes the generator.

When the generator shuts down or works at a lower capacity, this symbol appears.

The parasitic load (or the electricity used when an appliance goes down) exceeds the generating power.

When there is a power outage, the generator must continue to give power to appliances and other systems so that they may remain operational using standby power or a separate power unit.

Pumps, lights, HVAC systems, and other equipment fall into this category.

When the electricity generated exceeds the capacity of the commercial generator, intrinsic backfeeding occurs.

However, if you want to lower this and improve efficiency, make sure that the electrical utilities are on standby power or that the parasitic load is reduced.

How to Prevent Backfeeding in Your Generator

To prevent your portable generator from backfeeding to the power lines, utilize a transfer switch.

Things may rapidly spiral out of control without a transfer switch.

A transfer switch isolates the home’s electrical system from the utility lines by manually turning the switch on and off.

This is not only the safest solution, but it also permits electric power to flow via certain circuits inside your house.

Is It Possible To Use A Generator To Backfeed An Electrical Panel? (The Most Effective Option)

Legally Backfeeding your generator through your existing homes electrical panel! Using an Interlock! – 1D10CRACY

Backfeeding your generator via your home’s existing electrical panel is legal! Using an Interlocking Device!

Emergency systems must include a way to bypass and isolate transfer equipment, according to the National Electric Code [700.5(B) and 701.5(B)].

In this scenario, providing a transfer switch to utilize the generator is the safest option.

It is not needed, but it is permissible.

Whether you utilize this or not is dependent on a number of engineering choices and operational considerations.

If you experience a power outage, connecting a generator to the breaker box is safer.

As a result, you’ll need to employ a backfeeder breaker, either manual or automated, or manually transfer the switch using an interlock.

A manual transfer switch is not accessible on portable generators, although it is available on most other generators.

You’ll have to connect the transfer switch manually in such instance.

After the transfer switch is properly placed, the home’s circuits may be directly linked to the portable generator, eliminating the need for an extension connection.

How to Measure the Size of a Manual Transfer Switch

The maximum current in amps must be considered while determining the size of the transfer switch.

The sizes for household usage typically vary from 30 to 200 amps.

It’s not difficult to figure out what size you need.

Make a list of the household equipment that must be utilized in the event of a power loss (washing machine, fridge, oven, etc.).

After that, put the entire numbers together to get the amp’s size.

If you want more assistance, consult an electrician or someone you know who has specific experience.


To summarize, backfeeding redistributes energy throughout your house by reversing the flow of power.

A generator is then connected inside your house, which reverses the electricity and allows you to connect it to any device.

The issue of whether it is safe or not is a separate one.

Despite the fact that many homeowners insist on it, it may not be the best option.

Before you do anything you could regret, make sure you ask yourself all of the safety questions.
