What are the Directions and Stages for Electric Panel Assembly

Building your own electric panel is quite permissible. Given the range of finished goods available in the marketplace, another concern is if this makes sense. For a range of construction tasks, you can purchase a box in any configuration.

However, you need expertise and significant experience in electrical installation to complete the shield assembly accurately and qualitatively, such as installing automatic machines, switches, meters, as well as other equipment.

What Does an Electric Panel Mean?

An electrical panel, called breaker panel, seems to be a metal box having a door that is typically incorporated in a wall inside a secluded area of the home. All of the breaker switches of your home are located inside.

Breaker switches can be turned off and on. They are designed to automatically shut off if there is an excessive electrical current flowing through them.

A primary circuit breaker in an electrical panel regulates the electricity to the whole house. Also, you’ll see various breakers, every one of which takes charge of delivering electricity to different areas of your house. The section of a house which each breaker regulates should be noted on its label.

Several older homes lack breakers in favor of fuses. There won’t be any switches in the electrical panel if you possess a fuse box; instead, there will be screw-in fuses. You can have trouble getting insurance and you might have to spend more if your house still has a fuse box.

Your home’s electricity is supplied by electrical meters located outside, which then travels to the electrical panel. With the electric panel assembly main breaker, you can stop this primary electricity supply. The electrical service’s amperage is also displayed via your primary breaker (amperage can be described as an electrical current’s strength).

Electric Panel Assembly Components


These elements consist of:

Primary circuit breaker:  It’s comparable to disconnecting the primary electrical panel that serves a building’s entrance. In the majority of industrial applications, the primary circuit breakers manage voltages between 120V and 480V.

Surge arresters

It shields electrical components in the panel from overvoltage damage caused by lightning strikes and surges of utility power.


Transformers can step down the voltage to about 24V when the power incoming is 120V or reduce the voltage to about 120V for different components based on its incoming voltage.

Terminal Blocks

The numerous wires that originate from different sources and are distributed among various electrical equipment are organized and distributed with the aid of these blocks.

Programmable Logic Controller

In essence, the control panel is the CPU. This component, which serves as the control panel’s brain, monitors and regulates all mechanical operations. Several inputs as well as outputs from and to the production equipment’s automated operations will be included.

Contactors and relays

Based on instructions from this PLC, these off/on switches operate mechanical processes. Lights and fans are controlled by smaller relays. Larger relays, referred to as contacts, regulate functions that are more advanced such as motors, and more.

Network Switches. Network switches, which serve as the control panel’s communication hub, make it possible for the PLC as well as the different network-compatible machines on the assembly line to communicate with one another.

Human-Machine Interaction

These parts give the operator the ability to keep an eye on or manage specific machine operations. Joysticks, video monitors, buttons, keyboard, and switches are examples of common HMIs.

Directions for Electric Panel Assembly


When connecting electrical components into the electrical panels, do everything listed below:

  • Abide by the risk assessment, personal protective equipment, as well as other applicable safety laws systems or procedures in place
  • Observe all job instructions, instructions for assembly, and procedures.
  • Verify that the parts are free of contamination, damage, and extraneous objects.
  • Verify that the necessary equipment and tools are available in a tested, usable condition.
  • Prepare all the electrical enclosures/panels and electrical components for the different assembly operations
  • Make use of approved and safe techniques for the mounting of electrical components onto the panels as well as enclosures
  • Anywhere it is appropriate, apply the precautions and procedures to get rid of ESD (Electrostatic discharge) hazards, like utilizing grounded mats and wrist straps
  • Return all the equipment and tools to the right location when you are through with all the activities related to the assembly
  • Mount all the electrical components into the enclosures or panels to include some items. These include limit switches, plug-in device bases, enclosure partitions, capacitors, contactors, sensors, switches like toggle and pushbutton, resistors, overload as well as other relays, grommet strip, batteries, rectifiers, chokes/transformers, power supplies, fuses/circuit breakers.

How Can You Locate the Electric Panel Assembly

Metal boxes that are typically gray in color serve as electrical panels. They are typically built into a wall. Electricity panels include doors (they should, at least). You’ll find a variety of switches and wires behind the door; these switches can be described as your breakers.

Typically, electrical panels have been located in a remote area of your house. The electrical panel is frequently installed in storage rooms, basements, garages, or laundry rooms. In some older houses, you may even need to check outside your house before finding your panel.

This panel is most frequently found in flats either within the unit, close to a entrance, or within the bedroom, hidden behind your door.

The majority of residences only have one electrical panel, while some, particularly those with several living units.

Stages in Electric Panel Assembly

Setting Up the Cabinet for Installation

Installation from fresh often necessitates the inclusion of all electrical lines and wiring associated with the apartment (house) plan, as well as a niche inside the wall that has already been built by builders.

Such “landscape” often resembles a rectangular wall niche where a cabinet having the proper (acceptable) sizes must first be chosen.

If there isn’t a ready spot, you’ll need to carve out a niche yourself or use wall-mounted installation. For the second instance, the total dimensions of your electric panel assembly are taken into consideration when identifying an installation site. These are, in theory, ordinary building projects that present no unique challenges.

Interior control cabinet filling

Contemporary architecture is a little different. This cabinet is entirely composed of metal, as well as metal traverses are put within, on the back wall.

Every technical equipment, including the machine, switch, RCD, and other form of wiring accessories, is “placed on” those traverses.

Every one of the aforementioned components seems to have an installation design on the DIN rail in accordance with current requirements. Also, it is helpful to sign the equipment that has been mounted on a rail and to create a diagram having signatures of each resident of the apartment or house who uses power.

Considering the mounting on the traverses merely makes equipment installation and removal easier, you can obviously disregard these guidelines. But after that, you need to think about mounting choices that are reliable.

Wire Entry performance

The damaged power line should be routed within the built-in cabinet, together with cables and conductors that were pulled straight from the house or apartment. As a result, the box’s lower and upper sides will need to have an appropriate number of openings.

The hole diameters should allow for easy cable pulling. The protective ring must also be installed within every hole (plastic, rubber).

This conductor is often attached firmly into a cabinet wall throughout internal installation or/and to its base plate whereby the cabinet is fastened during the outdoor assembly using clamping clamps that are typically fitted at the outlet and inlet of a cable.

The grounding bus’ interface is also located on the bottom or side wall of a structure. If the bolted connection is supplied on this box body, a hole will be drilled for it or one that is ready-made can be used. During assembly, the earth bus would be linked to the connection.

Attaching the shield onto the wall

All of the aforementioned tasks are more practical to carry out outside the main installation’s zone. Namely, the preparation and assembly of that cabinet, the installation of the DIN rails, the positioning as well as fastening of the zero tires, the preparation of the through holes, the positioning of the communication equipment, and the installation of the door and lock.

Skilled electricians advise installing a prepared, completed, as well as a box that is partially equipped device in the chosen building niche.

Anchors are typically installed as part of a building project to secure your electrical panel. Without any, you must provide a solid base for the fasteners.

Attaching equipment to these mains

This shield is then completely outfitted with the necessary electrical components, and all of the functioning wires are inserted as well as connected in compliance with the created diagram.

This power line input and subsequent connection into the switch of the input package are located last inside the vicinity of an electrical panel. The centralized line from its batch switch is already connected to the circuit breaker.

Issues Related to the Electric Panel Assembly

Inadequate capacity

That can be an issue with capacity whenever you have any breaker which trips frequently (or numerous breakers). If only one breaker is the source of the issue, you can fix it by transferring certain electrical appliances to another circuit and taking them off the problematic circuit. You could require an electrician who can rearrange your breakers and add extra circuits if you lack sufficient circuits (for instance, all your kitchen’s outlets are on just one circuit).

In some circumstances, an electrician may include tandem or subpanels circuits to better effectively distribute power demand.

Short circuit

This circumstance is a little more serious. The short circuit will result from the contact of an electrified wire (referred to as “hot”) with another hot wire or neutral wire.

It can occur when you connect in a gadget with faulty circuitry and whenever mice or even other animals gnaw on the wiring. Finding the underlying cause of the short circuit can be challenging.

Breakers should be tripped by short circuits right away. The short circuit will be most probably to blame whenever you reset the tripped breaker but it trips once more right afterwards.

Turn off that breaker which governs power towards that outlet if you believe an electrical equipment is to blame for the short. Inspect your power cord for any melted parts and other damage. Examine the outlet and check for any dark stains or a burning odor. All of them indicate bad circuitry.

Ground fault

Ground fault occurs whenever the hot wire meets the ground wire or something else that is grounded, much like short circuits. When something is “grounded,” electricity can pass through it and reach the earth.

When electricity and water are combined, ground faults frequently occur. Consider the scenario when you drop the hair straightener while using it into a full sink. The ground fault will result from that, tripping the breaker. Your outlet can feature the ground-fault circuit interrupter is frequently the case in restrooms.


Electric panel assembly corrosion wiring surrounding them is a symptom of dampness. Electricity and moisture do not mix well (obviously).

But, if you simply notice corrosion and rust on this metal door and panel frame, it might not become a major issue because rusting might be brought on by moisture inside air. Just prime, sand, as well as repaint the panel.

But, corrosion upon this circuit breakers and electrical wiring can be far more dangerous. That might be an indication that water is getting into the electrical system, possibly via the exterior meter. Call the electrician when you find rusted wiring or switches.


Videos that demonstrate how to build the electrical panel is a useful tool for novice electricians. In order to greatly expand your knowledge base in this area, it is advised that you become familiar with this video training. A licensed professional electrician is required to access this supply line as well as connect consumers onto it.
