Troubleshooting Electrical Circuits for Industrial Workers

Troubleshooting electric control circuit is critical and helpful when it comes to helping reduce circuit overload. Electrical circuit control are devices designed to control the current flow of an electric current. It does this by turning ‘On’ and of ‘Off’ the electric current. They are specialized circuits designed to control the operations of a network of power circuits.

Basic elements of control circuit

For control circuits to perform the desired performance, it needs to have some of the basic components, which vary in size depending on the power of the motor. The principle operation remains the same. They include:

  • Manual Circuit breakers– open and closes the circuit especially when the current surpasses the predetermined limit.
  • Cam Switches -Consists of a different number of movable contacts that regulates the functionality of hoists and machine tools.
  • Control relays – They are in the form of thermal, time-relay and magnetic contactors. Works on electromagnetic principle and mainly used in low-power circuits. Their purpose is to open or close the power circuit.
  • Pilot Lights – Indicate the state of the remote component of the electric control circuit.
  • Across-the -line starters – They are of two types: manual and magnetic. They contain circuit breakers with mounted thermal relays. Their sole purpose is to regulate the starting and nominal full current thus preventing overheating. They also protect the motor from potential electric current overload.
  • Computer and controls – the technology has made it possible for some of the electric control circuit devices to be automated by use of a computer. Computers can stimulate the relay coils and contacts’ behavior.

Functions of an electric circuit control in industrial work

Electric control circuit plays a vital role in our industrial work:

  • Control more substantial amounts of voltages and currents that supply power to the tool
  • Used for controlling some equipment including breakers, motor, CP among other tools
  • Make a loop for feeding loads with electricity
  • Make a loop for tripping and protection of equipment, people, and power circuits
  • Acts as a bridge between the input and output circuits
  • In industrial work, they aid in the enhancing of overcurrent protection

Troubleshooting electric control circuits

This process is essential if you are getting overloads on a particular circuit. It would mean that you have to remove heavy electrical equipment such as a space heater or transfer it to another circuit. Tripping of breakers can be quickly eliminated especially when multiple items are using electricity at the same time. Although it may be confusing for an amateur trying to determine the position of the outlets on a particular circuit. There are different ways for troubleshooting circuits:

Checking for overload

Each control circuit is specific for a specific load or the amount of electricity it is supposed to use. Extra plugged in devices usually exceed the recommended load. To minimize cases of overload, you can acquire a plug strip or use many plug strips. It is not recommended to exceed the circuit breaker limits; this will lead to tripping. The only remedy to this is to remove the overload on the circuit by nut to replace the circuit breaker because it might be faulty.

Electrical shorts

Dead electric shorts do happen. In most cases when old or frayed wiring crosses each other at the wrong spot. It would lead to the shutting off the circuit breaker, which will trip easily. It is recommended to check all the wiring for the equipment plugged in.

Powerless box

Depending on the design of the power box, one loose wire can cause loss of power in the other boxes. When this happens, checking the connection of the first box would be the logical thing to do.

Power on one end of the connection and no power at the whole connection

First, you need to turn off the circuit breaker that feeds the connection. The voltage tester will come handy in identifying a problematic spot or box. You can also use the other option of joining the wires with a nut to the outlet.

Electrical safety training

Electricity has affected the lives of many people. The problem arises when it is not handled correctly. Some of the specific hazards associated with handling electricity equipment such as contact with a live wire that may cause burns or shock, electric faults that may cause fires.

It is paramount for workers to be made aware of the dangers associated with mishandling of electric equipment. The safety training outlines the requirements of the policies related to electricity and safety at workplace. This course also seeks to give individuals with limited electricity training background with electricity safety information and knowledge.
