Preventive maintenance of electrical systems: why it pays

18 April 2026 4 min read

Waiting for the breakdown is the most expensive strategy. Preventive maintenance acts before the problem appears, increasing safety and reliability and reducing unexpected costs, especially for businesses and offices.

What gets checked

A periodic check includes: inspection of tightening (loose connections are the leading cause of overheating), insulation measurement, RCD testing (test button and tripping times), the condition of breakers and contactors, plus cleaning and inspection of the panels.

Thermography

With a thermal camera we spot hot spots in panels and lines without interrupting service: a terminal that's heating up abnormally signals a problem before it becomes a fault or, worse, the start of a fire.

The concrete benefits

  • Less downtime: sudden faults are dramatically reduced.
  • More safety: protections and earthing always effective.
  • Predictable costs: planned work instead of emergencies.
  • Longevity: components last longer when maintained.

A tailored plan

We agree the frequency of checks based on the type of system and activity, with a logbook of interventions and clear costs. For companies it's also a safeguard in case of inspections.
