Everything You Need To Know About Electric Panel

The main power line of the house is connected to it by a service box called an electric panel, which also transfers electrical currents to the house's numerous circuits. When power is distributed to several circuits, overcurrents are prevented by circuit breakers and fuses.
There is a main circuit breaker in the electric panel that regulates the electricity to the entire house. Additionally, you will see various breakers, each in charge of supplying energy to a different area of your house. The section of the house that each breaker regulates should be noted on the device's label.

Previously fuses were used in place of breakers. There were no electric panel switches if there was a fuse box. Instead, they will screw in fuses. You can have trouble getting insurance, or your premiums might increase. Fuse issues and home insurance are discussed lower.
The electricity of the house is supplied via an electrical metre outside, which then travels to the electric panel. You can use the main breaker in your electric panel to turn off this primary electricity supply. You may also find out the current of your electrical service from the main breaker.


Types of Electric Panel

Main Breaker

The main breaker panel manages the energy that flows into the house's various rooms. The power to your home, including the circuit breaker, can be turned off. They are categorised according to the amperage and the number of circuits they can support.

Fuse Box

These are intended to avoid overloading the circuit. Small, electric panel-compatible fuses make up fuse boxes. In cases with excessive current flow, the fuse will break out.

Main Lug Panel

The line wires enter the lugs used in the main lug panels. They have a special connection at the metre, being the main breaker. The main lug panel, which serves as a sub-panel, can be connected to the breaker at the main panel.

Sub Panel

These are ideal for homes when you need several circuits in one location. For example, the central panel supplies electricity to the sub-panels through a circuit. Since they lack dedicated disconnects, you can change how the current is distributed throughout the house.

Transfer Switches

These are appropriate for circuits that make use of a backup power source. Through the panel, it converts generator power to electrical power to function. Transfer switches come in both manual and automatic varieties.

Components of Electric Panels

Main Circuit Breaker

This is comparable to disconnecting the main electric panel that serves any building or office entrance. Most industrial uses for main circuit breakers range start from 120V and goes up to 480V.

Lightning Protector

The lightning protector shields the circuit boards from getting damaged from overvoltage from the interior side of the panel caused by lightning or thunderstorms, or utility power surges.



Transformers can decrease the voltage to 24V when incoming power is 120V or drop the voltage to 120V for different components based on the incoming voltage.


The numerous wires come from various sources and are distributed among the various electrical equipment with the aid of these blocks.

PLC- Programmable Logical Controller

In essence, the control panel is a CPU on its own. The control panel's brain this component provides monitoring and management of all mechanical activities. There will be a variety of inputs and outputs to and from the production equipment's automated activities.

Contactors and Relays

These on and off switches operate mechanical processes by PLC instructions. More miniature relays are used to regulate appliances like fans and lighting. Larger relays referred to as contacts, manage more complex operations like motors.

Network Transister

This component serves as a communication means of a control panel, improving the connectivity that a PLC and the network-compatible machines have on the assembly line.

HMI- Human Machine Interface

These components enable the operator to monitor or control particular machine processes. For instance, common HMIs include video monitors, joysticks, buttons, switches, and keyboards.

Maintaining an Electric Panel

Another essential factor for electrical control panels is maintenance. A crucial component of designing a custom electrical control panel is making maintenance easier. Included in maintenance efforts should be:
  • Components, wiring, and terminals with prominent labels
  • Ability to keep track of the health of different electrical connections
  • Control of dust and particles inside the enclosure
  • Measures to manage pests
