Best practices for dealing with breakdowns in older buildings

Why are older buildings more vulnerable to electrical faults?

Older buildings are often equipped with obsolete electrical installations, designed for much lower energy requirements than today. These installations may suffer from aging wiring, inadequate circuit breakers or a lack of updating to current standards. In the event of a breakdown, it is essential to adopt appropriate practices to guarantee safety and effectively resolve the problem.

The essential steps for dealing with a breakdown in an old building

Identify the source of the fault

Check whether the outage is local or general: Consult your electricity supplier or ask your neighbors to find out whether the outage is network-related or limited to your building.
Inspect the electrical panel: Make sure the circuit breakers haven’t tripped. If they have, try resetting the main circuit breaker.
Test circuits: If a specific circuit-breaker consistently trips, the problem may lie with a particular circuit or appliance.

Switch off power supply if necessary

If you detect any signs of danger, such as a burning smell, sparks or unusual noises, switch off the power supply to the electrical panel immediately to avoid the risk of fire.

Assess the condition of your electrical installation

Look for signs of wear and tear: Cracked cables, blackened sockets or hot switches are all signs of ageing to be taken into account.
Make sure your switchboard is up to standard: In many older buildings, switchboards are undersized or fitted with fuses that no longer meet modern requirements.

Do not attempt to repair an old installation yourself

Older wiring is often complex and can be dangerous, especially if it’s not fitted with a ground fault circuit interrupter (GFCI) or if the wires are not properly insulated.
Call in a qualified electrician to inspect and repair the installation safely.

Upgrade equipment if necessary

Replace old circuit breakers with modern models suited to today’s loads.
Install an earth leakage circuit breaker (ELCB) if your panel has none, for added protection against electric shocks.
Distribute loads over several circuits to avoid overloads.

Protect your devices and circuits

Unplug sensitive equipment during the outage to prevent damage from power surges when power is restored.
Use surge protectors to protect your electronic equipment.

When to call in a professional?

If the fault persists after resetting the circuit breaker.
If you detect signs of advanced wear or abnormalities (noises, odors, blackened plugs).
If your electrical panel or wiring has not been checked or upgraded for several years.
