Your electrical panel is the heart of your home's wiring. Ignoring danger signs can lead to fire or electrocution. Not every click in a breaker means disaster, but some symptoms require immediate action.

Immediate danger signs — cut power and call an electrician

  • Burning plastic or rubber smell near the panel
  • Visible sparks when switching a breaker or switch
  • Panel or surrounding wall hot to the touch
  • Main breaker won't stay in the ON position
  • Electric shock when touching appliances

In these cases, disconnect the main breaker if safe, and don't restore power before inspection.

Signs needing inspection within 24–48 hours

  • ELCB/GFCI tripping repeatedly without clear cause
  • Lights flickering in more than one room
  • Outlet hot or melted
  • Continuous humming from the panel

Common repair costs

  • Electrician diagnostic visit: 250–350 ₪
  • Main breaker replacement: 350–500 ₪
  • ELCB/GFCI replacement: 400–600 ₪
  • Single-phase panel installation: 1,000–1,550 ₪
  • Three-phase panel installation: 2,500–3,150 ₪

Why does the breaker trip?

Common causes: overload (AC + water heater + washing machine on the same line), old wiring that can't handle current, corroded connections, or earth fault. The electrician measures load and decides whether a breaker swap or circuit redistribution is needed.

Older homes — pay attention

Homes built before the 1990s may have insufficient grounding or small panels that can't handle today's loads (ACs, instant heaters, EV chargers). Upgrading the panel isn't luxury — it's a safety requirement.

Before calling the electrician

Don't open the panel if you see moisture or pests inside. Describe precisely: when it started, which appliances were running, and whether it happened after rain. Photograph the panel if safe — helps remote diagnosis.

Panel upgrade — when is it necessary?

If you added ACs, an instant heater, or an EV charger, the old panel may exceed its load limit. The electrician calculates required amperage per circuit. Upgrading from single to three-phase (2,500–3,150 ₪) is a major project — get multiple quotes.

Grounding and safety

Proper grounding protects appliances and reduces shock risk. Replace old outlets without a ground pin. Don't use adapters to run heavy appliances on a standard outlet — a common cause of fires.

Breakers and loads — simple understanding

Each breaker serves a circuit (kitchen, room, AC). Adding a heavy appliance to a weak circuit trips the breaker. The electrician redistributes loads — don't «chain» appliances on one outlet with extension cords.

After the repair

Ask for a brief report: what changed, which parts, and whether follow-up is needed. Keep the invoice — useful for sale or insurance.

Bottom line

Don't experiment with electricity. Any burning smell or abnormal heat = stop and call a licensed electrician. Preventive maintenance is cheaper than fire repair or replacing appliances damaged by power surges.
