The terms "electrical panel" and "motor control center panel" are generally used to define a combination of enclosure, junction box, circuit breaker, power contactors, electrical fuses, protective relay, control unit and indicator.

Engine control center panel standards

The standards used in Europe often refer to IEC60050 for the definition of general terms. Unique IEC standards tend to provide more definitions of the equipment in question.

Example:

• IEC60439 و IEC60947 For low voltage equipment
• IEC60056، IEC60298 و IEC60694 For high voltage equipment. The older IEC 60277 standard has been abandoned.

IEC60439 is used for low voltage equipment as a set of factory structures, or FBAs for electrical switchboards and control switchboards.

These standards prefer the general terms "electrical panel" and "control panel". Control panel in the field of electrical panel training is also called "engine control center panel", which is a better known and specific term used in the oil industry.

Large parts of most equipment are supplied directly from high voltage lines. These lines use the 120V AC standard in most homes. Large parts of equipment such as motors, industrial machines, and large appliances (washing machines, dryers, etc.) typically use 240V AC and 480V AC. This voltage must be electrically disconnected from the 120V AC standard. Contactors are used for isolation. The contactors use a standard 120V power to connect a magnetic coil that provides a set of internal connections to get closer and provide more power to the equipment. You can also use these tips in the electrical panel assembly tutorial to learn how to install a contactor.

Contactor installation steps

Prepare the L-contactor to install the contactor.

Make sure the contactor connections are designed for both voltage and current to control the required equipment load.Contactors are available in construction and hardware stores, as well as in some large hardware stores.

Read contactor manufacturer information

Manufacturer information shows two input pins for 120V AC control. It may show two sets of output connections or more. These connections may be shown on the label as normally open (NO) and normally closed (NC). These connections may also be represented as one line from one connection reaching a point (NC connection) and another line from another connection near the point but not reaching the point (NO connection).

Check the auxiliary output connection.

Some contactors provide an auxiliary output connection, such as a signal, to the disconnected part of the circuit to which the contactor supplies power. This auxiliary connection is used at 120 volts AC and is not used at higher voltages.

Specify the wire path.

Disconnect all power to the wires. Connect all input and output wires to the contactor. These wires must be evaluated in the manufacturer's information. To cut the extra length from the end of the wire, use the crimp wire and make sure that the lengths of the wires are sufficient for the desired connection. Chinese wires are available at hardware stores and electrical supply stores.

Strip the wire.

Use crimp wire and strip one and a half inches (13 mm) from the end of each wire. If the wire is twisted, open the twisted wire to make sure there are no strands left. Scattered filaments may make improper contact with part of the equipment and cause damage.

Types of industrial electrical panels

Today, industrial electrical panels are used in almost all industries. These panels are enclosures for the installation of electrical equipment. To better understand industrial electrical switchboards and electrical switchboard design, electrical switchboard assembly training by experienced professors will be of considerable help to people who are interested in working in this field. Industrial electrical panels are divided into different categories according to their application, which are introduced below:

Electrical panels include PLC with PLC Panel

Switchboards include programmable logic controllers, or PLCs, which are smaller in size than contact and relay switchboards and allow easy control and monitoring of input and output through programming.Electrical switchboards included PLC They are one of the most important and effective electrical panels and are used in various industries.

MCC or MCC Panel Engine Control Center Electrical Panels

Motor Control Center stands for Motor Control Center. MCC panels include one or more compartments with power bus that are used to install separate devices such as switches, fuses, drives, soft starters to ensure protection against short circuit, isolation and control of various loads. .

Power Distribution Panel PDF or Power Distribution Panel

Power distribution panels, while protecting against overcurrent, are responsible for distributing power to different circuits.

Automatic power factor control panels or APFC Panel

Automatic Power Factor Control stands for Automatic Power Factor Control.APFC panels have controllers based on microcontrollers that automatically change the capacitance of capacitor bank capacitors in several steps.

HMI Operator Panels or HMI Operator Panel

I Human Machine Interface stands for human-machine interface. HMI boards provide a user-friendly graphical interface for the operator and facilitate matters such as monitoring, controlling and troubleshooting equipment or production line operations.Electrical switchboardsHMI In terms of hardware, various forms such as  free standing،  wall mounted  arm mount ، are made.

SCADA or SCADA Panel panels

Abbreviation for Supervisory Control And Data Acquisition, which means control and data collection system. SCADA switchboards allow control and monitoring of an unlimited number of processes from multiple locations for multiple users. The main advantage of SCADA systems is that the control software is located only in the central location And all users can access the system through an application via the Internet.

An electrical panel is a box (enclosure) that inside or on it is a suitable place for installation and wiring of electrical and electronic equipment. Electric shock is used to them. The electrical panel is a device to protect electrical equipment against environmental factors.

The switchboards have 2 standard models: 1- International standard 2- American standard

In terms of voltage, switchboards are divided into two categories: MV switchboards and LV switchboards. MV switchboards are switchboards that have a voltage between 1000 and 36000 volts. LV switchboards are switchboards that have a voltage below. Be 1000 volts.

Low voltage switchboards in terms of application can be divided into 6 categories: 1. Industrial switchboards that are used in industrial units to distribute mains electricity from the switchboard. 2- Residential electricity distribution board that is used in residential units to distribute network electricity. 3- Capacitor bank switchboards that use this switchboard to correct the power consumption factor to reduce the amount and amount of power consumption. 4- Motor control panel of electric motors that use this electrical panel to control and start electric motors. 5. Electrical control panel (PLC) which is used for automatic control of electrical circuits. 6- Marshall electrical panel that provides the connection between the electrical panel and the central control panel or DCS panel.
