The objective of this Electrical Preventive Maintenance Scope of Work (SOW) is to outline the procedures, frequencies, and safety protocols for maintaining electrical systems and equipment within [COMPANY NAME]. This SOW aims to ensure the safety, reliability, and optimal performance of electrical systems while minimizing downtime and reducing the risk of electrical hazards.

This SOW covers preventive maintenance tasks for electrical systems and equipment including, but not limited to, electrical panels, circuit breakers, transformers, switchgear, distribution boards, lighting systems, and power distribution units (PDUs).

Maintenance Technicians: Responsible for performing scheduled preventive maintenance tasks and reporting any abnormalities or issues.

Facility Managers: Responsible for overseeing the implementation of preventive maintenance activities, ensuring compliance with safety protocols, and allocating necessary resources.

Safety Officers: Responsible for ensuring that all maintenance activities comply with relevant safety regulations and guidelines.

Clients: Responsible for providing access to facilities and cooperating with maintenance schedules.

The frequency of preventive maintenance tasks may vary depending on the criticality of equipment, environmental conditions, and manufacturer recommendations. However, as a general guideline:

Quarterly Maintenance:

• Inspect and clean electrical panels, circuit breakers, and distribution boards. - Tighten electrical connections.

• Test ground fault circuit interrupters (GFCIs) and arc fault circuit interrupters (AFCIs).

• Inspect lighting systems for proper functioning and replace bulbs as needed. - Test emergency lighting systems.

Bi-Annual Maintenance:

• Inspect and test transformers, switchgear, and power distribution units (PDUs).

• Conduct thermal imaging inspections to detect hotspots.

• Perform insulation resistance testing.

• Check voltage levels and phase balance.

Annual Maintenance:

• Conduct comprehensive inspection and testing of all electrical systems and equipment.

• Verify the operation of surge protection devices.

• Perform power quality analysis.

• Test and calibrate protective relays.

Visual Inspection:

• Check for signs of corrosion, overheating, or physical damage on electrical equipment.

• Ensure that electrical enclosures are clean and free from obstructions.

• Inspect for loose connections, frayed wires, or damaged insulation.

Electrical Testing:

• Measure voltage, current, and resistance levels.

• Perform insulation resistance testing.

• Conduct earth/ground continuity testing.

• Test functionality of protective devices such as circuit breakers and fuses.

Cleaning and Lubrication:

• Clean dust and debris from electrical panels and equipment.

• Lubricate moving parts as per manufacturer recommendations.

• Remove any vegetation or debris from outdoor electrical installations.

Documentation:

• Maintain comprehensive records of all maintenance activities, including test results, repairs, and replacements.

• Keep equipment manuals, schematics, and safety guidelines up to date.

Personal Protective Equipment (PPE):

• Maintenance technicians must wear appropriate PPE, including insulated gloves, safety glasses, and arc flash protection gear.

• Safety officers should ensure that all PPE is properly maintained and replaced as needed.

Lockout/Tagout (LOTO):

• Implement LOTO procedures before performing any maintenance work on electrical systems to prevent accidental energization.

• Use lockout devices and tags to clearly indicate when equipment is undergoing maintenance.

Electrical Safety Training:

• Ensure that all maintenance technicians are trained in electrical safety procedures and aware of potential hazards.

• Conduct regular refresher training sessions to reinforce safety protocols.

Hazard Identification:

• Identify and label electrical hazards such as exposed wires, overloaded circuits, or damaged equipment.

• Erect barriers or warning signs to prevent unauthorized access to hazardous areas.

Emergency Preparedness:

• Maintain emergency response plans for dealing with electrical accidents or incidents.

• Provide training on emergency procedures and ensure that appropriate emergency equipment, such as fire extinguishers and first aid kits, is readily available.

This Electrical Preventive Maintenance Scope of Work is designed to ensure the safe and reliable operation of electrical systems and equipment within [COMPANY NAME]. By adhering to the outlined procedures, frequencies, and safety protocols, we aim to minimize the risk of electrical failures, enhance equipment lifespan, and maintain a safe working environment for all stakeholders involved. Continuous monitoring, timely maintenance, and proactive safety measures are essential for achieving these objectives.
