Why this page matters
The symptom is not always the source.
Our Venice Canals case involved a compact Siemens panel serving an elevator, large central air-conditioning equipment and Level 2 EV charging. We evaluated the breakers, bus, conductors, terminations and connected loads to identify the dangerous overheating condition.
A focused diagnosis helps avoid random part replacement, repeat visits and leaving the real failure hidden elsewhere in the circuit or service equipment.
When to call quickly
Do not wait on these warning signs.
- Buzzing changes when large loads start
- The cover or breaker feels unusually hot
- You smell burning insulation
- There is smoke, crackling or flickering
