The Power Assemblies Electrical Tap Box

Side, Open, and Front view of Tap Box

What exactly is an electrical tap box you might ask? Well, it’s a vital component for portable and permanent portable power distribution applications. Electrical Tap boxes, also known as splitter boxes or pull boxes, are essentially junction boxes equipped with a backplate that holds individual copper busbars for each phase and mechanical chairs lugs that you can tap into with large cables such as 500 MCM and greater. These lugs allow you to then distribute power throughout multiple smaller cables such as 2/0 or 4/0 AWG outbound to your desired power distribution unit.

The main purpose of a tap box is to provide a specified location where you can land larger feeder cables for more efficient distribution purposes. Our goal with the Electrical Tap Box was to provide consumers with a solution to provide high-quality, safe, and sustainable electrical junction boxes for easy connection and distribution of large wires and cables throughout the desired area.

The Power Assemblies Electrical Tapping Junction Box is available in single-phase or three-phase arrangements from 400A up to 3000A. Our tap box has been carefully designed and engineered to offer an alternative connection point to that of the standard pull-boxes that are currently on the market.

How to Choose the Appropriate Electrical Tap Box

When it comes to choosing the correct splitter or tap box for your preferred application, it really just comes down to that, the application. Depending on the intended purpose of the box, there are a number of different configurations that Power Assemblies engineers have developed for the tap box.

When deciphering what kind of Tap Box best suits your needs, it’s important to consider the size of your incoming and outgoing cables, the voltage, the total amperage needed to power the load, and any limitations that may occur in the process. These constraints can range from a limited amount of space on your wall, the total number of units needing power, and even the total budget for the job. It’s important to figure out all these questions before your preferred electrical distributor can provide Power Assemblies engineers with the information needed to construct the perfect electrical tap box for your application.

Electrical Tap Boxes In Commercial Business

Tap Boxes are convenient for commercial and industrial businesses that may require standby generators in the event of a power outage. These types of buildings usually have an electrical room loaded with automatic transfer switches, transformers, and other switchgear required to power the building accordingly. Often times, buildings such as airports, supermarkets, hospitals, and data centers will require load bank testing of their generators to ensure sufficient power is available on site in case of an emergency situation.

In scenarios like this, it is very convenient to have a tap box installed where you can run cables out to the designated units during planned downtimes and maintenance testing procedures with a load bank station. Now in order to test your standby generator properly in this particular situation, you’re going to need a little bit more than just the tap box itself. This could require a standby generator, a portable generator, a load banking station, generator cables, and the tap box to land larger wires to then down-size into smaller wires to each additional distribution unit.
