The importance of electrical maintenance

If you own or run a business or household, it’s essential to carry out electrical maintenance regularly. Electrical maintenance covers all aspects of testing, monitoring, troubleshooting, repairing, and replacing electrical equipment. Advances in and reliance on electrical equipment make businesses vulnerable if a piece of machinery or a vital electrical system shuts down. For this reason, electrical maintenance is an important part of a smooth-running business.

1. What is electrical maintenance?


A licensed electrician carries out electrical maintenance. The task revolves around maintaining and repairing electronic equipment used in commercial, industrial and residential buildings. It covers areas including:

  • Digital communication and computer software issues.
  • Electrical machines.
  • Generators.
  • Hydraulics and Pneumatics.
  • HVAC systems.
  • Lighting systems.
  • Surge protection.
  • Electrical transformers.
  • Regular electrical maintenance is recommended for most commercial, industrial, and residential properties to safeguard existing systems and ensure that all electrical equipment is operating.

2. Why it is important?

We live in a far more digitized world, with reliance on technology and digital communication evermore widespread. Electrical maintenance is necessary for businesses since any electrical failure can cause extensive downtime and data loss. Additionally, the regularity of widespread damaging weather events has also brought electrical maintenance to the forefront.

Electrical maintenance is important and should be carried out regularly and properly. Emergency and standby generators are our first line of defense in an emergency; if these fail or are faulty, they could become a safety hazard.

One of the major challenges to electrical maintenance is the nature of electrical wiring since the complexity of locating specific problems and locations can be difficult for anyone other than a professional. An irregular or neglected electrical maintenance program can render all the services that your business or household relies upon useless. Early identification of all these issues is a key aspect of electrical maintenance.

3. What are the main areas covered?

Electrical maintenance is primarily carried out to ensure equipment is operating without fault. This is necessary to manage electrical risks. Some items of electrical equipment carry more risk than others, with portable equipment vulnerable to damage on the plugs and sockets, electrical connections, and cables.

Extension leads are also pieces of equipment to be carefully monitored and inspected, with many of these items becoming hazardous in wet surroundings or cramped spaces. Electrical shock is one of the main hazards when it comes to using or handling electrical equipment, so maintenance is carried out to perform safety checks and to eliminate hazards like:

  • Contact with exposed live parts.
  • Electrical faults that could lead to a fire.
  • Explosions or fires where electricity could be the source of ignition.
  • Electrical maintenance covers installing electrical systems and equipment, safety checks, and risk control measures.


4. Common reasons businesses need electrical maintenace

  • Electrical safety should always be a priority in the workplace. Electrocution is one of the most common electrical hazards, with the potential to be fatally injured. Along with physical risks, electricity can also result in computer issues leading to outages, data losses, and slow internet speeds, which can cost a business time and money. Regular electrical maintenance as part of your business plan will ensure the safety of the dwelling and its occupants.
  • Lighting, security systems, and fire alarms must also be maintained regularly to provide safety and a comfortable working environment. If the business operates large machinery or dangerous equipment, electrical maintenance can be carried out as a preventative measure to ensure all equipment is safe and faultless. Staff should never carry out any electrical work, with businesses urged to employ a professional electrician to carry out any maintenance or repairs to ensure everything is handled safely.

5. What are electrical maintenance tools?

  • Hand tools include wire cutters, insulation pliers, insulation screwdrivers, hacksaws, wrenches and strippers, and hammers.
  • Measuring devices, such as AVO meters, insulation resistance testers (megger testers), and grounding resistance testers.
  • Test equipment, such as transformer oil breakdown voltmeter, CB and overload tester, and transformer rev ratio meter.
  • Other maintenance tools and equipment include transformer oil filter, thermal imaging camera, and vacuum cleaner for panel cleaning.
  • Maintenance computer programs such as MAXIMO and ORACLE maintenance.
  • These maintenance tools and equipment may be relevant to our electrical maintenance activities. Each task has its requirements for tools and equipment. You should prepare your tools and equipment and start the maintenance work.



Electrical maintenance is a preventative measure to eliminate any risks associated with electrical equipment. It ensures that all electrical systems and components are working and that any faulty or damaged equipment is replaced or repaired.

Businesses should have regular electrical maintenance carried out by a professional to prevent any safety hazards or risks and ensure that all business data and related security are protected during an outage.
