Terminal Box – The Definitive FAQ Guide

Every electrical system consists of smaller devices and connections needed for proper functioning.

These parts also need housing, especially when they are used on harsh industrial sites and power plants.

For this purpose, terminal boxes and enclosures can be used.

What is the terminal box?

The terminal box is an enclosure that includes, mounts, and protects one or more terminals or terminal boards.

It might include a cover and such accessories as mounting hardware, brackets, locks, and conduit fittings.

A terminal is a point at which a conductor from a component, device or network comes to an end.

A terminal may simply be the end of a wire or it may be fitted with a connector or fastener.

Where is the terminal box used?

In general, terminal boxes can be used in any application where there is a need to house connections or small devices, like regulators.

Thus, terminal boxes can be successfully used in the next cases. 

# 1. Terminal box for HVAC

Terminal boxes are devices in HVAC systems that are located close to rooms and control airflow to those rooms.

In practice, terminal boxes can contain temperature or air regulators.

# 8. Terminal box for street light

As well as in the case of lighting fixtures, terminal boxes can be used as regulators, or simply to connect street light devices together.

The main thing about such terminals is their ability to withstand harsh weather conditions, like strong winds, rains, etc.

Street light pole box

# 9. Terminal box for hazardous areas

Speaking of manufacturing sites, a possibility of hazardous influence is much more likely in such places.

For example, there can be a massive heat dissipation on-site, or a possibility of mechanical impact, so such terminal boxes have to be able to withstand such influence.

# 3. Explosion-proof terminal box

The explosion-proof terminal box is needed on the chemical and petrochemical plants, offshore platforms, refineries and any other industry where hazardous atmospheres (gas and combustible dust) are potentially present.

Such boxes and enclosures can protect the equipment from explosive impacts, as well as from dangerous particles.

Explosion-proof box

# 4. Three-phase terminal box

Three-phase electric power is a method of alternating current electric power transmission and distribution.

Due to its effectiveness, this method is the most common when it comes to modern electric applications.

The three-phase voltage is 415V.

Three-phase plastic box

# 5. Single-phase terminal box

The single-phase power supply has one distinct wave cycle and requires the single wire to connect the circuit.

Its voltage is 230V.

Single-phase terminal box

# 6. Low voltage terminal box

Low voltage refers to the mains voltages as used by domestic, light industrial, and commercial consumers.

# 7. Interface terminal box

With the help of the interface terminal box, it is easier to view and operate with the inner equipment.

Windowed or screwed removable covers are used for this purpose. 

# 8. Terminal extension box

Extension of the terminal box can house extra wires and connections that also require protection.

# 9. Outdoor terminal box

To secure inner devices and make them weatherproof, outdoor terminal boxes utilize the best materials and designs.

Such boxes have to go through hard testing procedures before going on the market.

What materials are used for the terminal box?

There are four materials used widely by manufacturers when producing terminal boxes:

  1. Stainless steel terminal box.
  2. Steel terminal box.
  3. Aluminum terminal box.
  4. Plastic terminal box.

Steel terminal boxes are heavy, but they provide great impact protection.

Stainless steel gives boxes even more strength, as well as additional protection from rust.

Aluminum terminal boxes have practically the same useful qualities as steel, however, aluminum weighs less and has better conductivity qualities.

Finally, plastic terminal boxes are the cheapest and have lesser weight.

Due to it, they can be easily installed and moved.

Stainless steel boxes

What is the terminal box HS code?

Several categories can be applied in the case of terminal box HS code.

For more information, please, follow this guide.

How to wire terminal box?

The wiring of the terminal box depends on the chosen type.

For example, a single-phase connection utilizes single wire, so its installation doesn’t have to cause any troubles.

When it comes to a three-phase connection, the main rule is that each conductor carries an alternating current of the same frequency and voltage amplitude relative to a common reference but with a phase difference of one-third of a cycle between each.

Please, watch the following video to learn more about terminal box wiring.

How to mount terminal boxes?

Typically, terminal boxes are wall-mounted, with the help of screws or DIN rails.

Before beginning the mounting procedure, be sure that your electrical equipment is disconnected.

Mark the wall surface for future holes and put the box to them.

Fix the screws inside the holes designed near the edges of the box and fasten them.

Pole mount box

How to install and replace a terminal box?

First of all, you have to mount the box on the wall or other needed surface.

Then, screw the terminal inside the box.

Afterward, the wiring procedure is performed: all cables are connected in the terminal following the type of connection (one, two, or three-phase).

The replacement of the terminal box follows the same steps in backward order.

After you disconnect the terminal box from the circuit, de-attach wires and terminal from it.

Then, you can easily remove the box from the wall or another surface.

Please, read this guide if you want to learn more about the wiring and installation of terminal boxes.

When you need a waterproof terminal box?

Waterproof terminal boxes can withstand direct jets of water and successfully protect equipment from small drops and any other kind of water influence.

We’ve already mentioned marine and outdoor junction boxes, which are of course waterproof.

However, these are not the only examples.

Let’s mention public pools and spa facilities: all thermoregulators and connection boxes have to be waterproof.

Also, let’s not forget about port facilities and other organizations located near the seaside: all electrical systems in such places have to withstand high humidity.

Waterproof terminal box

What is the difference between the terminal box and the junction box?

Junction boxes are boxes with no components mounted in it (i.e. all connections are wire nuts or split bolts).

Most conductors are long enough to be pulled from the box (i.e. the 6″ length required at devices)

Terminal boxes are boxes with components (i.e. terminal strips) mounted in it.

Most conductors are trimmed to length to fit into the terminal (like in a load center).

Junction boxes need to be accessible but don’t require working clearance.

Terminal boxes would require working clearance.

  2. IP54 terminal box can withstand splashes of water, and protect the pieces of equipment from dust particles and small objects.
  3. IP55 terminal box can withstand weak water jets and has the same protection from hard objects as the previous type.
  4. IP56 terminal box protects the inner equipment from powerful jets of water and dust particles.
  5. IP57 terminal boxes have the same dust protection as all IP5* enclosures, but can be immersed in water up to 1 m.
  6. IP65 terminal box is dust-tight, which means that even tiny particles of dust can’t get inside it; this box also withstands water jets.
