What is a Distribution Box

The distribution box is a component used in a larger electrical system that helps regulate the flow of electricity through the distribution board. Distribution Boxes provide the orderly flow of current so that circuits will not overload or lead to potentially dangerous situations. The distribution box is usually equipped with a solid case that is capable of protecting interior components from adverse environments and different application conditions. Its wirings and parts are mounted within the interior to lessen the interior components from damage during shifting that creates abrasive actions on wire coverings. Electrical distribution boxes are airtight and watertight, allowing easy access to the interior components for inspection, and replacement.

Types of Distribution Boxes

The distribution box’s main functions are breaking up the power supply into sub-circuits depending on the purpose, ensuring everything within the circuit is safe against short circuits, and distributing power to different areas from the main power source. Distribution box also comes in different sizes depending on the types of distribution board size to use. Below are the type of distribution boxes you commonly encounter in an electrical system:

Main Breaker Panel

This is the most commonly used type of distribution box. The main breaker panel protects the circuits and controls the amperage capacity of the circuit. It also protects the circuit from overheating and protects the power supply by shutting down, including the circuit breaker when there is a fault or short circuit.

Main Lug Panel

The main lug panel is a type of distribution box used in an upstream breaker. The wires are connected to this lug and the main lug panel is used as the sub-panel when connecting to the main panel. With this type of distribution box, the separate disconnection in the meter can be used during a fire or emergency. It will serve as the main breaker and discontinue the power supply even before it enters the building.



Subpanels are used when you have multiple circuits within a certain area. It is efficient for residential homes and very easy to install. Subpanels are connected to the main panel through the circuit. It draws power from the main and adjusts distribution around the multiple circuits around the area or property. Subpanels distribute power to a specific part of the house and work as satellite circuit breaker panels in the area.

Transfer Switch

The transfer switch is a type of sub-panel. It is used when the power load needs to be shifted from one source to another. Transfer switch transfers generator power to electrical power with the help of the breaker panel. It is convenient to use as a backup power generator unstable and unpredictable. Transfer switch also has two kinds of manual and automatic transfer switches. Manual transfer switches operate manually when switching the electrical load to the backup power. An automatic transfer switch uses to get temporary electrical power during a power disruption from a generator. It is seamless and easy to use and preferred by most residential units.

Unitized Panel

A Unitized panel is an exclusive electronic display that gives electrical parameters. It is used in a power-centered supply and delivers a low-voltage panel from a medium-voltage line. Unitized panels are used for industrial and commercial establishments.

Panel Fuse Bank

This type of distribution box serves as the load center of the distribution system. Panel Fuse Bank provides electrical safety protection on an over-current electrical circuit. It is ideal for distributing electrical power from a solar panel. The electricity will be stored on the solar panels and go directly to the fuse box before being distributed to the entire residential circuit unit.

Industrial Lighting Panel

Industrial lighting panel reduces energy consumption in industrial establishments by programming the lights to turn off during the idle period.

Material Used in Distribution Box Manufacturing

Below are the three most used materials for electrical distribution box manufacturing. This varies depending on the type of distribution box produced.

Sheet Molding Compounds (SMC)

SMC is a group of plastics made up of polymeric material that undergo irreversible chemical changes. This kind of material also undergoes curing wherein it is heated. It is a non-recyclable material that requires post-process operation after molding. SMS are electrically non-conductive and usually finish in an uneven mat with fiber-chipping edges.

Polycarbonate (PC) and Acrylonitrile Styrene Acrylate (ASA)

This kind of material is malleable when heated and rigid when cooled. Common plastic distribution boxes are made up of TPC and ASA which don’t require post-process operation and have a smooth glossy aesthetic finish. These materials are also recyclable.

Epoxy Coated Steel

The metallic sheet is drawn to form the shape of the enclosure with mechanical means. It has a high impact strength and does not require post-process operation after drawing. This is electrically conductive and must be coated with epoxy to achieve non-conductivity.

Things to Consider when Choosing the Right Distribution Box for Your Use

There are several factors to consider when choosing the right distribution box for your project. Below are the key things to check before purchasing.

The location where it will be installed

Installation positions are one of the main factors to consider before buying your distribution boxes. It will determine what level of dust and waterproofing is required and the material will be used for your distribution box.

Number of Circuits

To determine the number of poles required, you should first determine the number of outgoing circuits. RCD-protected single-phase circuits will need 1 pole each and three-phase circuits will need 3 poles each for a standard circuit. And in computing, the number of circuits to use is always a lot a portion for future expansions.

Load and the Total Amount of Current Required

Know the load in order to determine if you require to use MCB or RCBO protection. All circuits have a maximum load current amount required. It is important to know the total amount of current you require for each circuit to select the appropriate size of the protection device.

Is the Main Switch Required?

It is important to determine if the main switch will be required in choosing the right distribution boxes. The main switch may not be required if the board can be isolated at a nearby location like a main board. Whether the main switch is required may also be determined by the state or supply authority wiring rules.

Things to consider in Choosing the Right Distribution Box Manufacturer

All distribution box manufacturers offer different scopes and kinds of customization according to your need. Providers often give consumers the will to make their boxes custom fit to their project applications by listing the specifications they needed. But there are also other factors to consider when choosing your distribution box manufacturer.


Cost is the main factor to consider in choosing the right distribution box company. The price of your distribution box will be based on the customization you need for it. Manufacturers often offer this kind of service but will charge additional payment according to the specifications made. Some manufacturers also give a minimum or maximum order that will also affect the cost.


In finding your best distribution provider, you also need to ask about the benefits you’ll be gaining. From the quality of the product, reliability, cost-effectiveness, and even warranty.

Rank your Options

Make a list of all your manufacturers/providers and rank it according to the two factors given above. Cross out the least and do more research for the main one to conduct another layer of examination based on testimonies and portfolios of your chosen manufacturers/providers.


The distribution box is a vital asset to any commercial or industrial electrical circuit. This ensures that all buildings are properly connected to the same power source and the property will not lose power even in a power outage. These boxes can also be used to distribute other utilities such as cable, internet, and fiber optic services to businesses. With a distribution box, you do not require digging, trench, or pipe drilling, which is one of the best features a distribution box has. With the above’s content information, you are able to basically understand what is a distribution box, its usage, and how important its role in any electronic circuit application for residential to commercial spaces. We also give a list of the best distribution box manufacturers in the market, their backgrounds, and the services to offer. This guide will surely help you find the right distribution box for your project
