Best Preventative Electrical Maintenance Checklist

When it comes to commercial electrical maintenance, sometimes the best defense is a good offense. Performing regular preventative electrical maintenance on your Dallas-Fort Worth Metroplex, TX commercial or industrial building is a great way to stay in compliance with local laws and avoid catastrophic problems in the future.

But because of the immense amount of power required, electrical systems in commercial buildings present different types of challenges than do residential power grids. You should have a professional electrician check your company’s power system at least once every three years. For in between check-ups, here are some guidelines outlining what you should be checking:

Why having a checklist is important

Depending on the type of commercial building you have, there will likely be governing bodies that provide a framework for what you need to be inspecting. But those lists aren’t always complete and/or applicable to the type of business you are running.

This list won’t be exhaustive, but it should be a good starting point for you to begin preventative electrical maintenance.

Checklist for commercial electrical preventative maintenance

  • Locate and check each power meter to make sure it’s functioning correctly. You’ll be turning these off for maintenance.
  • Check the various warning lights, sensors and indicators in your commercial building to ensure they’re working properly.
  • Inspect all your building’s bolted electrical connections, and perform the requisite torque tests on them, if necessary.
  • Perform visual inspection of main control points. You’ll be looking for signs of physical degradation and overheating.
  • Check and disassemble any battery tripping packs that you have. See if there’s any corrosion or heat damage, and ensure that the batteries are still intact.
  • Using special thermography equipment, you’ll want to conduct precise thermal imaging surveys.
  • Thermal imaging surveys will allow you to check your building’s heat profile. Watch for any areas that are consistently overheating, and note those, because you may need to replace or repair any parts from those areas.
  • Check motor control circuits, and ensure that they’re properly protected from overcurrent.
  • Locate all motor disconnects, and verify that they’re close enough to the motors while also being easily accessible for maintenance.
  • Inspect any multi-unit conductors, and confirm that they’re adequately supplying power to all their associated units.
  • Confirm that feeder short-circuit protection, as well as ground-fault protection, are sized correctly in relation to their application.
  • Make sure that any transformers rated at 1,000 volts or more have the proper overcurrent protection. If they don’t, you’ll need to have some installed.
  • Examine transformers, and confirm the presence of fail-safe components and/or the ability to disconnect immediately.
  • Perform a comprehensive survey of all commercial machinery and moving systems, including things like elevators and platform lifts. You’ll want to ensure that the systems are wired properly and that the correct amount of voltage is being supplied to them.
