5 Reasons to Use Plug Joint Connectors for Pre-Wiring Prefab Homes

Prefabricated homes are a fast-growing segment of the housing market. They have many characteristics that make them a popular choice for a new home, but the most obvious advantage is in how they’re constructed. For instance, electrical prefabrication can simplify the work at the construction site by pre-wiring the modules at the factory. Once the parts of the home arrive at the build site, it’s simple enough to connect the modules together to provide power to the entire building.

Those who choose to use Nichifu for their electrical prefabrication needs will be able to significantly reduce the time it takes to complete a new home construction. In this article, you’ll see how the incorporation of our plug joint connectors during the pre-wiring process will benefit both homeowners and builders alike.

Prefabricated Homes

According to a 2020 study by The Freedonia Group, demand for prefabricated homes in the United States is expected to reach a market value of $10.8 billion USD by 2024. The study offers several factors that are spurring such demand. One is a shortage of affordable housing due to the amount of time and money needed to construct site-built homes. Prefabricated homes have an advantage in this arena, as modules are rapidly constructed and assembled on site for far less than the traditional site-built home.

Another factor is the increasing interest in multigenerational living across the United States. The recent economic impact of COVID-19 has brought the home to the forefront for Americans across the nation. Many parents are required to stay home with children, or may be hesitant to send their aging relatives to nursing homes. As such, Americans are looking for solutions to housing several different generations of their family tree under one roof. Prefabricated homes again offer a solution, either in the form of add-ons to an existing home or nearby constructions to accommodate additional family members.

To sum, new home manufacturers can expect to see an increasing demand for prefabricated homes and the flexibility and affordability they provide to consumers. Indeed, the Freedonia study makes it clear that consumer concerns are what’s driving the market at this time. So, what can new home manufacturers do to ensure they’re ready to meet this demand?

When it comes to building prefabricated homes, manufacturers will need to show that their building process offers the highest quality of service to the homeowners that will be enjoying the final product. Take the necessity of electrical prefabrication, for instance. As we move into the third decade of the 21st century, continued changes in consumer concerns could spell trouble for new home manufacturers who fail to complete the pre-wiring process at the factory.

For instance, homeowners might desire a rush installation on their home. Given the uncertainty surrounding the COVID-19 pandemic, new and seasoned homeowners alike are looking for a sense of stability when it comes to their homes. This is the place where they’ll be quarantined should a lockdown occur, and they need their homes to be available without delay. Setbacks will only serve to frustrate the homeowner and poison their relationship with the manufacturer. Businesses who choose to pre-wire electrical components at the factory can ensure that construction proceeds as quickly as possible.

Sustainability is another important issue that modern-day homeowners are likely to take into account when choosing a prefab home manufacturer. Many Americans are concerned about climate change, green energy, and leaving a small environmental footprint throughout their lives. Such homeowners might request that the parts of their home have a low-impact on the environment—including the electrical components. They may even desire the construction of a tiny home, where manufacturers would need to provide the capability for the wiring of compact electrical components.

Moreover, these homeowners are likely to desire the addition of energy-efficient components after the build process is complete. Manufacturers who provide safe and flexible pre-wired modules are likely to win the hearts of such consumers. Lastly, increasing globalization brings an additional concern to the table for today’s homeowners. For those who might desire to relocate their home at some point in the future, electrical components in prefabricated homes must be easily disassembled.

As demand for prefabricated housing rises, so too do the individual demands of the homeowners who will be living in the constructed homes. The coronavirus pandemic has shown Americans nationwide the importance of a safe, stable home environment. As a result, prefabricated home manufacturers can expect a heavy list of demands to accompany the request for a new construction. Those who are prepared to tackle those demands will have an undeniable edge over the competition.

Plug Joint Connectors

Electrical prefabrication is the process of assembling the wiring for electrical components inside of prefabricated home modules. When the modules arrive at the build site, they’re ready to be installed—sometimes, with the simple push of a plug! Pre-wiring a new home ensures that manufacturers remain ahead of the competition. The final product will not only have the wiring for TV, Internet, security, lighting, and other systems ready to go; but it may also be future-proof, ensuring that homeowners will be able to modify and extend the electrical components of their home as they wish.

Nichifu’s plug joint connectors are well suited for the pre-wiring of prefabricated home modules. In the next few sections, we’ll take a closer look at the product specifications to see how our plug joint connectors can help you to smoothly and safely include electrical prefabrication as part of your construction process.


With traditional methods, connecting electrical wires can be a difficult process. It often requires stripping insulation and crimping the connection—and if done improperly, small interruptions to the connection can cause the crimp to come apart. It’s absolutely crucial that homeowners aren’t presented with a newly constructed home that has faulty wiring from the start.

As an alternative, the Nichifu plug joint connector provides you with quick and easy connections. Indoor electrical wiring becomes extremely simple: you only need to plug the wires directly into the terminal block to make the connection. As such, our plug joint connectors are especially efficient for the pre-wiring of prefab homes. After installing the electrical wires into the wall, floor, or roof at the factory, all that’s left to do is to push the plug into the tab block at the build site.

What’s more, our plug joint connectors eliminate the need for junction boxes. These small, metal boxes often end up hidden in hard-to-reach places, like under a floor, deep inside a wall, or behind an access panel, where they can cause a fire hazard if sparks were to fly. What’s more, homeowners who might attempt to access these junction boxes without professional help can find themselves in a dangerous situation—which could lead to a lawsuit at the manufacturer’s expense! Thankfully, our plug joint connectors eliminate these concerns; our product has been approved by the Japanese Electrical Appliance and Material Safety laws for use without a junction box.


When you’re working to pre-wire a prefabricated home, workers may be tempted to try and complete the process as quickly as possible. Laborers are particularly at risk of this when homeowners are impatient about the build process, or when there are construction setbacks and delays. Unfortunately, workers who try to rush the pre-wiring process using traditional methods are not likely to ensure that all connections are made properly and securely. What’s more, improper connections can lead to safety hazards or even loss of human life.

Our plug joint connectors take some of the guesswork out of wiring electrical components. To prevent improper connections, we’ve ensured that the plug and terminal block have the correct mating mechanisms. Furthermore, the transparent housing plug allows you to visually inspect the connection to be sure that it’s secure and properly polarized. With this, you can quickly and safely expedite the completion of the pre-wiring process for prefab homes.


Homeowners in the 21st century are likely to be concerned about the sustainability and reusability of the various parts of their home, including electrical wiring and electrical components. When using traditional plug connectors, this might not always be the case: these are components that, for the most part, were never meant to be removed or rewired ever again.

To try and reuse traditional plastic wire plugs, a homeowner would need to go through the exhausting process of extracting and re-connecting the likely metal terminals that house them. For traditional plastic terminal connectors, if they’re damaged in the rewiring process, then they can be difficult to replace. They may have even been coated with a sealant, one which might be toxic and non-biodegradable. Homeowners who are environmentally conscious are likely to recoil at the thought of the “guts” of their home causing such waste for the planet.

When you choose to include our plug joint connectors as part of your pre-wiring process, then you’ll be able to offer environmental peace-of-mind to your green clients! The plug and terminal block are both reusable, and the terminal removal method is extremely simple. To take off the wires, you simply press the lock release lever using a flathead screwdriver on the plug. The homeowner or their hired electrician will be able to quickly and easily perform rewiring work in almost any electrical setup—without sending damaged wires and soldered plugs to the landfill!


While you might strive to make detailed plans in order to have everything on hand to complete the manufacturing process, obstacles are bound to arise that derail these plans along the way. For instance, workers may discover that there simply isn’t enough wiring to complete one of the modules for a prefabricated home. It may be tempting to try and stretch the wires to force the connection, but this isn’t optimal. On the safe side, you’d have a faulty connection and the homeowner would be at risk of losing power at some point in the future. On the more dangerous side, you could be introducing an unnecessary safety hazard into your homeowners’ electrical setup.

Thankfully, there’s a safer option. Our plug joint connectors make it easy to connect multiple lengths of wire. If the current wire length has been reached, it’s simple enough to connect the end to the start of a new wire, thereby extending the length of the cord. By changing the terminal block, it even becomes possible to make single-line or double-line connections. Furthermore, our plug joint connectors are able to handle the stranded copper wires that might be used for pre-wiring indoor components, such as circuit boards and electronic devices. Nichifu plug joint connector attachments will allow you to take advantage of stranded wire connections when pre-wiring a new prefab home. Using the cover and pin terminals, the plug will accept stranded wire, allowing you to work with those indoor electrical components that need a bit more flexibility.


Last but not least, it’s important to ensure that you’re using the correct plug joint connectors for the appropriate size of wire for the construction in question. For example, tiny houses and micro prefabricated homes will obviously require a pre-wiring setup that can accommodate wires with a smaller diameter. Fortunately, we offer a product that will allow prefabricated home manufacturers to cover their bases when it comes to thinner wires. Our mini plug joint connectors are available in a compact size that’s made for use in a wide variety of tight-fitting spaces. They can pass through an opening with a diameter as small as 25mm.

The straight-line connection is male and compact, and the terminal block can be used for joint branching. You can make a connection with just a simple touch, and remove it just as easily by using the wire lock release lever. Because the connection is directional, there’s no need to worry about miswiring. Furthermore, the transparency allows you to check the wire insertion status and polarity. Using our mini plug joint connectors during the pre-wiring process reduces work time, saves labor costs, and improves the quality of the final electrical wiring system.
