Preventive Maintenance Schedule for Electrical Panel Boards

 

Electrical panel boards are used everywhere electricity is distributed. They might go by other names like:

  • Distribution board
  • Breaker panel/box
  • Electrical panel
  • DB board/box
  • Consumer unit
  • Circuit breaker panel
  • Fuse box (still used conversationally…even when housing breakers instead of fuses)

Regardless of the name, panel boards are the specific part of electrical distribution systems responsible for dividing the main power supply into branch circuits that deliver power to different areas. The panel board protects the circuits from overloading or shorting out with fuses or circuit breakers.

The Importance of Preventive Maintenance Schedules for Electrical Panel Boards

A panelboard in electrical systems is an essential component and maintaining this power supply hub is of paramount importance.

The best way to avoid electrical failure, and the high costs of emergency repairs, is to develop a solid electrical preventive maintenance program for panel boards and all other components of your system.

Preventive Maintenance Schedule Checklist

Using an electrical preventative maintenance checklist is easy. And it’s important to conduct scheduled maintenance on electrical components to prevent problems.

However, there are numerous types and sizes of electrical equipment installed that require maintenance tasks varying in frequency and effort. It is essential to consider what types of equipment you’re dealing with before executing a regularly scheduled checklist.

Top 4 Maintenance Considerations

1. What’s the Market?

This is probably the most obvious differentiator for utility providers. Installed equipment can vary greatly between residential, commercial and industrial facilities. Special or niche facilities may require more detailed or out-of-the-norm maintenance plans like:

  • Healthcare
  • Entertainment venues
  • Aquatic or water-related
  • Campuses
  • Temperature-dependent environments

2. Geography and Environment

Second to the market is the environment surrounding the utility. Solar utilities in Africa are going to have a different checklist than solar utilities in Canada. Environmental conditions to consider include:

  • Weather ranges/patterns
  • Moisture, dirt, dust and sand tendencies
  • Access challenges due to physical structures or topography
  • Access challenges due to geopolitical or cultural norms

3. Equipment Age

The age of equipment must be considered when developing maintenance practices due to the differences in requirements of old and new equipment.

Design expansion can mean changes in electrical system loads over a period of time. The worldwide increase in digitization means more load consumption in general. Advanced age may increase the likelihood of equipment failure.

4. Country-Specific Standards

Routine maintenance and standards often start with a framework from electrical safety associations or governing bodies like the Institute of Electrical and Electronics Engineers, OSHA or the National Fire Protection Association.

Compliance standards will vary by country but they are a good place to start when compiling your own preventive maintenance schedules.

Depending on the above factors, some facilities may have their own power supply plants. Some may employ dedicated electrical maintenance teams.

Special occupancy facilities like hospitals may have more stringent preventive maintenance needs. Taking this into consideration, individual checklists will vary.

They may include:

Inspection and Monitoring Tasks

  • Visually inspect primary controls for deterioration and overheating.
  • Conduct a general survey of electrical connections in residential areas.
  • Examine boxes for warning lights and other indicators.
  • Confirm that indicators, lamps, sensors, and warning lights are functioning correctly.
  • Check locking devices on electrical units for signs of damage or wear.
  • Examine all outdoor and indoor lighting and relays for signs of wear or dimming.
  • Inspect lighting outlets to ensure correct wiring on specified circuits.
  • Survey branch circuit types for all applicable receptacle outlets.
  • Inspect grounding electrode conductor connections.
  • Conduct a detailed survey of all machinery and moving systems.
  • Inspect, repair, and/or replace supply lines for alternate power sources.
  • Visual inspection of all bus bars and accessories.
  • Conduct a final visual inspection of panels, boxes, and other major system components after maintenance work.

Maintenance and Repairs

  • Clean, vacuum, and visually inspect switchboards, circuit breakers, inlets, panel boards, and electric distribution systems.
  • Inspect and repair capacitors, transformers, and wiring manifolds.
  • Identify and mend any frayed wires.
  • Examine and repair surge protection units.
  • Disassemble battery tripping packs and check for signs of battery integrity.
  • Inspect all control circuits and check for overcurrent protection.
  • Ensure proper insulation along panel boards and outlets.
  • Relocate excess power consumers and balance supply as needed.

Testing and Verification

  • Check all power meters for functionality before shutting down.
  • Torque test and inspect bolted electrical connections to specified levels.
  • Perform thermal imaging surveys where necessary.
  • Ensure proper voltage in all rooms and areas of electrical usage.
  • Check if multi-unit conductors are properly supplying all units and are correctly rated.
  • Verify that ground-fault and feeder short-circuit protection is sized according to the specific application.
  • Confirm transformers have adequate overcurrent protection.
  • Check meter voltage connections, current transformer connections, and modbus connections.

Safety and Compliance Checks

  • Check for loose connections, short circuits, and signs of burning.
  • Ensure grounding conductors are working properly with installed equipment.
  • Check that all labels are correct and in place.
  • Inspect countertop, wall floor, and ceiling receptacle proximity and spacing in relation to cold, heat, and water.
  • Ensure the number of receptacles is in compliance for special occupancy facilities.
  • Check to see if power sources and feeder capacities are adequate and review load calculations for essential systems.
  • Inspect supply routes to critical life-support systems.
  • Check all air circuit breakers (ACBs) for continued integrity of mechanical and electrical components.
  • Ensure the “all clear” after work is completed, but before fitting covers.
