When power issues surface, minutes matter. As a facility manager, you need a fast, repeatable way to decide if you are looking at an electrical emergency, who to call first, and what to do before help arrives. This guide gives you clear criteria, a triage checklist, and a calm plan of action built for commercial, industrial, and institutional facilities in the Chicago area. What qualifies as an electrical emergency? An electrical emergency is any condition that presents an immediate safety hazard, threatens critical operations, or risks major property damage. In practical terms, treat the following as emergencies that require immediate action: Burning smell from panels, switchgear, MCCs, or junction boxes, especially a hot, acrid odor Visible arcing, sparking, or smoke from equipment, conductors, or bus bars Repeated tripping of a main breaker or feeder that will not reset or trips again under minimal load Partial building outage affecting life safety systems, egress lighting, elevators, fire alarm panels, or critical areas Equipment critical circuits down, for example process lines, server rooms, medical equipment, refrigeration, or pumps Water intrusion in electrical rooms, panels, conduits, or ceiling spaces with energized components Exposed live conductors, damaged gear after impact, or signs of overheating such as melted insulation or discoloration A burning or sizzling sound coming from distribution gear, transformers If you suspect imminent danger to people or the facility, treat it as an emergency, isolate power if safe to do so, and evacuate the area. Is an electrical fault an emergency? It depends on the fault and its impact: Emergency, act now: Faults that trip mains or feeders repeatedly, produce heat, arcing, smoke, or odors, or involve moisture near energized equipment. Urgent, same day: Faults that disable a critical process or life safety circuit even if there is no obvious hazard, for instance emergency lighting not functioning or a failed sump pump circuit during a storm. Non urgent, schedule soon: Single circuit nuisance trips that are load related, intermittent receptacle failures in non critical areas, or lighting outages that do not affect life safety. When in doubt, prioritize life safety and continuity of operations. If a fault affects egress lighting, fire alarm power, medical spaces, or essential process control, treat it as an emergency. Rapid triage checklist Use this quick sequence to decide your next steps: 1. Protect people Keep staff and occupants away from the affected area. If you smell burning, see smoke, or hear arcing, evacuate that zone. 2. Make safe, only if trained If you are authorized and it is safe, open the nearest upstream disconnect or main to de energize the affected section. Do not open gear covers. Do not touch wet equipment. Do not attempt resets repeatedly. 3. Identify the scope Note what is down, entire building, specific panel, selected floors, or isolated equipment. Check life safety impacts, emergency lighting, fire alarm panels, elevators, access control, sump or booster pumps. 4. Determine the likely source Utility side indicators: Wide area outage, utility transformer issues outside, multiple neighboring buildings out. Facility side indicators: Only your building or a portion is affected, tripping at your main or feeders, localized burning smell or water intrusion. 5. Call the right party Utility: Widespread outage or visible damage to service drop, meter, or utility transformer. Emergency electrician: Anything on your side of the meter, including panels, feeders, gear, and internal distribution. 6. Document Record breaker labels that tripped, alarms, smells, locations, water sources, and what was operating at the time. When should you call an emergency electrician? Call immediately for: Burning smell, smoke, arcing, or heat from electrical equipment Repeated main or feeder trips that do not hold after a single reset Water intrusion near energized equipment, including roof leaks into electrical rooms Loss of power to life safety systems or critical equipment Damage from impact, flooding, or fire suppression discharge Any shock incident or suspected energized exposed conductor If the outage appears to be utility related, call the utility first, then call an emergency electrician to prepare for make safe actions and rapid restoration when service returns. Who do you ring if you have no electricity? Call the utility if the outage is area wide or the issue appears on the utility side, visible downed lines, neighborhood outage, damaged service drop. Call an emergency electrician if the outage is limited to your facility or a section of it, your main or feeder tripped, there is evidence of internal faults, or critical equipment is down even if some power remains. In the Chicago area, TCL Electrical & Lighting provides 24/7 support for commercial, industrial, municipal, and healthcare facilities. What should you do in an electrical emergency? Follow a calm, safety first protocol: Keep people clear. Establish a temporary exclusion zone. Post a runner or barricade if needed. De energize if safe. Use labeled disconnects upstream of the suspected fault. Do not open gear or expose conductors. Do not use water on electrical fires. If a rated extinguisher is available and you are trained, use Class C or multi purpose ABC. Ventilate smoke only if it does not draw air across energized equipment. Avoid resets. One controlled reset may be acceptable after load checks, but repeated resets create additional risk. Control moisture. Stop leaks at the source if possible. Do not enter standing water that may be energized. Call the utility or an emergency electrician promptly. Provide panel names, breaker numbers, areas affected, and any alarms. Preserve evidence. Do not discard damaged components. They are needed for root cause diagnostics and documentation. TCL’s 24/7 Emergency Response Team process When you call, our team follows a structured response: 1. Dispatch You reach our on call coordinator any time of day. We confirm site safety conditions, collect system details, and mobilize the right technicians with PPE, metering gear, and temporary power equipment. 2. On site make safe We secure the area, verify absence of voltage, and isolate the faulted segment. Life safety circuits are validated first. 3. Temporary power Where needed, we deploy portable panels, cords, and transfer equipment to maintain critical loads while permanent repairs are planned. 4. Root cause diagnostics Using thermal scans, insulation resistance tests, load analysis, and point to point verification, we identify failures across panels, feeders, transformers, and controls. 5. Follow up remediation We replace or repair damaged equipment, correct code issues, and implement preventive measures. We provide documentation for compliance and insurance. Our goal is straightforward, stabilize the site, restore safe operation, and prevent repeat incidents. How ongoing maintenance prevents emergencies Most electrical emergencies trace back to heat, moisture, overload, loose terminations, or aging components. A preventive program reduces risk and downtime: Routine thermal imaging to catch overheating terminations and overloaded circuits Torque checks and cleaning for panels, switchgear, and MCCs Periodic testing of emergency lighting and egress circuits Inspection of seals, penetrations, and drainage to prevent water intrusion Load studies to balance phases and right size breakers, feeders, and transformers  Arc flash labeling updates and single line diagrams for faster, safer response If you need a partner for planning and rapid response, our team supports emergency repairs, power distribution systems upgrades, and electrical safety compliance across the region. Clear examples, emergency or not? Burning smell from panels, emergency, evacuate the area and call immediately. Tripping main, emergency if it will not hold after a single reset or trips under light load; call now. Visible arcing, emergency, isolate and call. Partial building outage, emergency if life safety or critical operations are affected; otherwise urgent same day. Equipment critical circuit down, emergency for healthcare, server rooms, refrigeration, pumps, or production lines. Water intrusion in electrical rooms, emergency, de energize affected equipment if safe and call. Internal coordination tips Keep an updated panel schedule and single line diagram accessible. Tag critical loads and provide a priority list for temporary power. Maintain a call tree with utility, facility leadership, security, elevator service, and emergency electrician contacts. Stage basic supplies, barricade tape, signage, flashlights, and absorbents for minor water control away from electrical rooms.
