Electrical Troubleshooting in Valbonne and Mougins: Securing a Faulty Three-Phase Installation

REGIS ELECTRIC, a professional electrician regularly working in Valbonne and Mougins, recently carried out an electrical troubleshooting intervention on a three-phase installation with a major design flaw.

A common electrical issue in Valbonne and Mougins homes

Our client, located in Valbonne, had been dealing for years with a recurring electrical problem:their three-phase electrical panel was protected by a single residual current device (RCD) for the entire house.

The result was simple and very frustrating:

• Any electrical fault caused a total power outage

• The freezer lost power, leading to food loss

• The alarm system kept triggering repeatedly

• Daily stress and no long-term solution, despite the issue lasting for years

This type of situation is very common in older houses in Valbonne and Mougins, especially where three-phase systems have never been properly upgraded or reorganized.

Why a single RCD is a problem on a three-phase installation

When a whole house is protected by only one differential device:

• A minor fault cuts power to the entire property

• Sensitive equipment is not isolated

• Outdoor circuits cause unnecessary tripping

• Comfort, safety, and reliability are significantly reduced

This is a configuration we regularly encounter during electrical troubleshooting in Valbonne and Mougins.

The REGIS ELECTRIC solution: safety, reliability, and continuity

After a full diagnosis, REGIS ELECTRIC, specialist in electrical troubleshooting in Valbonne and Mougins, implemented a simple, efficient, and long-lasting solution:

• Installation of two additional residual current devices

  • One RCD dedicated to outdoor circuits, which are more exposed to moisture and electrical faults

  • One RCD dedicated to critical equipment, including:

    • The freezer

    • The alarm system

  • 
    

This new electrical panel configuration allows:

• Fault isolation without cutting power to the entire house

• Protection of essential appliances

• Improved electrical safety

• Continuous operation of critical systems, even in case of a fault elsewhere

Fast and efficient electrical troubleshooting in Valbonne and Mougins

As with all our electrical troubleshooting interventions in Valbonne and Mougins, the work was carried out:

• Quickly

• With a clear and precise diagnosis

• Using solutions adapted to the client’s real needs

The result: a very satisfied client, finally free from an electrical problem that had been impacting their home for years.
