What is an Outdoor Distribution Box?

Outdoor Distribution Box1

A weatherproof junction box, also known as an Outdoor Distribution Box, is an enclosure designed to protect external electrical cabling and connections from damage caused by water and dust infiltration.

Chapter1:Outdoor Distribution Box Defined?

Outdoor Distribution Box1

As you read in the introduction, an Outdoor Distribution Box can go by different names. You can call them Exterior Electrical Boxes or junction boxes, but they all refer to the same thing.

Outdoor electrical junction boxes are designed to safeguard and secure important electrical connections in any setting, even underground.

Waterproof junction boxes are sturdy and durable for outdoor usage, but they may also be utilized for inside applications since they meet a range of NEMA and IP classifications.

Outdoor junction boxes are available in various forms, including hinged covers or knockouts and wall and pole mounting choices.

It’s simple to discover the ideal electrical junction box solution with plastic, aluminum, and steel alternatives available in various sizes. Check out our article on different types of junction boxes.

Chapter2: Types of Outdoor Distribution Box

By material used

Metal and Plastic Electrical Boxes

The majority of electrical boxes are made of metal or plastic. Steel is used in metal boxes, whereas PVC or fiberglass is used in plastic boxes.

Aluminum is commonly used to make weatherproof metal boxes for outdoor applications. A metal box is necessary to utilize a metal conduit to route wire to the electrical box, anchoring the conduits. The conduit and metal container combination may be utilized to ground the system.

Using a non-metal cable, such as Type NM-B, a non-metallic sheathed cable, you can use plastic or metal boxes as long as the cable is properly secured with a cable clamp.

Because modern NM-B cable wiring systems frequently have a ground wire inside the cable, the grounding system does not need a box. But metallic boxes should be linked to the system ground, typically with a shorter wire (pigtail).

By number of gangs

2-Gang, 3-Gang, and 4-Gang Boxes

These contain home switches and electrical outlets the same way as normal rectangular boxes do, but they are enlarged so that two to four devices may be put side by side.

They come in various “new work” and “old work” styles, some having built-in cable clamps, just like other boxes. Standard rectangular boxes with a “gangable” construction allow the sides to be removed and the boxes to be connected to make bigger boxes achieve the same result.

By shape

Standard Rectangular Boxes

Standard rectangular boxes, or “single-gang” or “one-gang” boxes, generally fit single light fixture switches and outlet receptacles. Their dimensions are typically 2 by 3 inches, with depths varying from 1 1/2 to 3 1/2 inches.

Some models are “gangable,” meaning they have detachable sides that you may remove to make bigger boxes that can house two, three, or more devices side by side.

Traditional rectangular boxes are available in various “new work” and “old work” styles. For securing NM cables, certain models incorporate built-in cable clamps.

Octagon and Round Electrical Boxes

The typical cabinet for wall-mounted or ceiling light fittings weighing up to 50 pounds is the octagon or regular-size round box, which is 1 1/2 to 3 inches deep.

They may be used as junction boxes and provide more wire space than shallow circular pan boxes. Metal boxes are ideal for surface-mounted metal conduit installations.

In existing or “old work” applications, round plastic boxes sometimes feature “ears” for attachment to the wall or ceiling surface. Instead of making a huge hole in the drywall to connect the box to the frame, they allow you to secure the box to the drywall (or other surface material).

Round Pan Electrical Boxes

The normal round pan, or “pancake,” box is just 1/2 inch or 3/4 inch deep. They’re most typically utilized for light fixtures installed on the ceiling or wall and weigh less than 50 pounds.

Ceiling fans may be mounted in some types of specifically approved metal pan boxes, although not all pan boxes can be used for this purpose.

The fixture wires must be correctly connected and installed inside the round pan box. These are small electrical boxes that can only accommodate two or three electrical connections.

If additional wire connections are to be made, a full-sized octagon or circular electrical box with more volume would be required. The number of cables within should never exceed the electrical box’s safe fill capacity.

Ceiling Fan-Rated Electrical Box

Ceiling fan boxes are available in various shapes and sizes, including 1/2″ “pancake” variants and typical 2 1/8-inch-deep boxes.

They are often round, although they can also be octagonal. Ceiling fan boxes should be UL-listed and tagged “For Use With Ceiling Fans.”

Do not use normal round or octagonal boxes for ceiling fan installation. Ceiling fan boxes require the appropriate fastening to endure the dynamic loads of a revolving fan.

Most ceiling fan boxes are certified for fans or light fixtures that weigh up to 75 pounds, depending on the installation technique.

Boxes can be attached to adjustable bracing spanning between ceiling joists or directly to a ceiling joist or wood blocking (with four screws).

4-Inch Square Box

Square boxes are available in typical depths of 1 1/4 to 2 1/8′′, but their square corners provide extra internal space, allowing for more wires and connections.

As a result, 4-inch square boxes are frequently utilized to run several conductors in different directions. They’re also known as junction boxes, and when paired with the appropriate cover plates, they may be put in ceilings or walls to support lighting fixtures or house switches or receptacles.

Chapter3: Is IP65 better than IP67?

Outdoor Distribution Box1

The initial digit of both IP65 and IP67 enclosures is “6,” indicating complete protection against solid object intrusion.

Gasket seals on each enclosure design can often block out even ultra-fine particles. As a result, both are suited for most dust-tight outdoor applications.

The main distinction between an IP65 and an IP67 grade is the level of liquid ingress protection provided. Both are water-resistant, but the meanings of their second digits reveal the varying levels of protection built into their designs.

Chapter4: What’s the difference between waterproofing and weatherproofing?

The distinction between waterproofing and weatherproofing is that waterproofing means the interior is unaffected by water. However, weatherproofing can withstand damage caused by the weather, providing resistance to a wider range of scenarios than being saturated in water.

Chapter5:What is the IP rating?

Each of the digits that follow IP has a distinct meaning. The first reveals how effectively humans are protected from moving components and how protected well-enclosed equipment from foreign bodies. The second specifies how well the enclosure is protected from various types of moisture.

Chapter6: Conclusion

Outdoor Distribution Box1

Outdoor Fiber Distribution Boxes include several features that you may customize to meet your specific requirements.

The first distinction is whether you want your fiber distribution box loaded or empty when you buy it. The fiber adapters and pigtails that come with Loaded Distribution boxes add to the ease of having everything you need in one location.

One disadvantage of the loaded distribution unit is that if one port is broken or you wish to update the unit, you must replace the entire device.

Unloaded patch panels do not have these restrictions, but they do not include the components needed to terminate and distribute the bulk wire entering the enclosure.

Because you must construct the unit individually, this option is more expensive, but depending on the needs of your project, it may be the best alternative.
