Commercial Electrical Panel & Switchgear Flood Inspection

We evaluate, test, and repair the electrical equipment. The utility handles utility-owned equipment such as the meter and service transformer, restoration contractors handle water extraction and structural drying, and the manufacturer is involved when switchgear reconditioning is considered. For flooding that affects the whole building, see our commercial flood damage response service.

What a Panel and Switchgear Flood Inspection Is

A panel and switchgear flood inspection is the process of finding out which electrical equipment floodwater reached, deciding what must be replaced, what may be reconditioned, and what can return to service, and proving that the system is safe before power is restored. The goal is a documented decision for every component, not a general impression that the equipment looks fine.

The work follows NEMA’s guide to evaluating water-damaged electrical equipment, which calls for evaluation by qualified personnel, consultation with the authority having jurisdiction and the manufacturer, and testing such as insulation resistance, dielectric absorption, and infrared thermography. The guide also notes that floodwater may be contaminated with oil, chemicals, and sewage, which is one reason the evaluation is careful rather than quick.

Panel and Switchgear Flood Inspection Services

Safe Entry and De-Energization Verification

The first step is confirming that the equipment is isolated and safe to approach. We coordinate with the utility when service equipment or the meter is affected, and our electricians follow NFPA 70E safe work practices around any equipment that could be energized.

Visual and Physical Inspection

We inspect enclosures, busbars, terminals, and interiors for water lines, silt, corrosion, and discoloration, record nameplate and manufacturer information, and photograph conditions. The inspection establishes how high the water rose and which components it reached.

Component Replacement

NEMA’s guidance lists molded-case circuit breakers, fuses, switches, wiring devices, connectors, and electronic trip units as items to replace after exposure, and the Consumer Product Safety Commission states that circuit breakers, GFCIs, and fuses that were underwater cannot be repaired. We replace these components with listed products suited to the equipment.

Electrical Testing

Qualified personnel test insulation resistance and dielectric absorption with calibrated instruments and compare results with the manufacturer’s requirements. NEMA lists infrared thermography among the evaluation methods. Because it requires equipment to be energized under load, we use it as a follow-up check once it is safe to restore power.

Switchgear and Switchboard Reconditioning Coordination

NEMA’s guidance limits reconditioning of switchgear assemblies, switchboards, panelboards, motor control centers, and drives to work involving the manufacturer. We evaluate the equipment, contact the manufacturer, document the findings, and consult the authority having jurisdiction when needed.

Replacement Switchgear, Panelboards, and Distribution

When reconditioning is not possible or not appropriate, we replace equipment and plan the sequence to limit downtime. Our circuit breaker panel and sub-panel services and power distribution upgrades teams handle the replacement and restoration.

Grounding and Bonding Check

Grounding and bonding connections in the affected area are part of the evaluation. Our grounding and bonding systems service describes how those connections are inspected and tested, and our Fishers grounding and bonding covers the local service.

Documentation and Reporting

We deliver a written report that lists each assembly and component, its condition, the tests performed, and the decision to replace, recondition, or return to service, with photographs and nameplate information.

Common Ways Electrical Equipment Is Exposed to Water

  • Rising water in below-grade electrical rooms from river or flash flooding.
  • Drain and sewer backup into rooms that house panels and switchgear.
  • Water entering through conduits that run underground or through exterior walls.
  • Roof leaks and rooftop equipment failures that drip onto equipment below.
  • Sprinkler discharge or pipe failure above electrical equipment.
  • Wind-driven rain through penetrations, louvers, and damaged enclosures.

Local Data: Flooding and Electrical Equipment in the Indianapolis Area

The National Weather Service in Indianapolis documented the August 2026 flooding, with heavy rain from August 11 to 17 and record crests on the White River at Noblesville and Anderson. Marion County station reports ranged from 2.66 to 5.90 inches, including 5.10 inches at a Lawrence station, while Hamilton County reports ran higher, with 6.87 inches at Noblesville. Rainfall at those levels puts below-grade electrical rooms, underground conduit entries, and roof penetrations to the test, and the same exposure patterns apply to any heavy storm. From our Lawrence headquarters, we serve properties across Indianapolis and central Indiana.

For Hamilton County properties, see our Carmel commercial flood damage response and Fishers commercial flood damage response. For mechanical equipment that took on water, see our rooftop and mechanical unit water damage service. To reduce exposure before the next storm, read our guide to flood-proofing a commercial mechanical room.

Codes and Standards for Flood-Damaged Electrical Equipment

Evaluation follows NEMA’s guidance, and work on or near potentially energized equipment follows NFPA 70E and OSHA’s electrical safety requirements. Repairs and replacements follow the National Electrical Code as adopted in the Indiana Electrical Code. Replacement of panelboards, switchgear, and service equipment typically requires permits and inspection through the City of Indianapolis or the applicable local jurisdiction, and Mission Mechanical coordinates permitted work.

Frequently Asked Questions: Panel and Switchgear Flood Inspection

It is a structured evaluation of the electrical equipment that floodwater reached, including service equipment, switchgear, switchboards, panelboards, disconnects, and related components. Qualified electricians inspect, test, and document each item, decide whether it is replaced, reconditioned with the manufacturer, or returned to service, and verify the system before power is restored.
Yes. Flood inspection and repair work is performed by Indiana Licensed Commercial Electricians. Mission Mechanical carries full general liability and workers compensation insurance, is BBB A+ accredited, and has served central Indiana commercial properties since 2002.
We evaluate service entrance equipment, switchgear, switchboards, panelboards and sub-panels, disconnects, motor control centers, drives, transfer switches, and the associated wiring and devices that were exposed to water. Utility-owned equipment, such as the meter and service transformer, is handled by the utility.
Flood damage to electrical equipment can be difficult or impossible to detect, so equipment that is re-energized before it has been evaluated can fail. Qualified personnel should inspect and test it first.
In most cases breakers cannot. NEMA's guidance on water-damaged electrical equipment says molded-case circuit breakers, fuses, switches, wiring devices, connectors, and electronic trip units should be replaced. Federal consumer safety guidance states that circuit breakers, GFCIs, and fuses that were underwater cannot be repaired.
A breaker is a safety device whose job is to interrupt current correctly during a fault. The Consumer Product Safety Commission states that water and silt inside these devices prevent them from performing properly as safety devices, and that even if they appear to function after submersion they are unfit for continued use.
No. Water that enters through conduits, drips from above, or splashes into equipment can reach internal parts. The evaluation considers how the water reached the equipment, how high it rose, and how long it stayed, and it determines what must be replaced or tested.
NEMA notes that floodwater may be contaminated with oil, chemicals, and sewage. Contamination affects how equipment is handled and cleaned, whether it can be reconditioned, and the precautions needed for the people doing the work.
NEMA's guidance lists molded-case circuit breakers, fuses, switches, wiring devices, connectors, and electronic trip units. Federal consumer safety guidance adds GFCIs. Replacement parts should be listed products suited to the equipment they go into.
NEMA's guidance limits reconditioning of switchgear assemblies, switchboards, panelboards, motor control centers, and drives to work involving the manufacturer. Qualified personnel evaluate the equipment first, and the manufacturer and the authority having jurisdiction are consulted on whether reconditioning is acceptable.
The manufacturer knows the design, materials, and test criteria of its equipment and can specify what may be cleaned, repaired, or replaced and how the result should be verified. NEMA's guidance limits reconditioning of assemblies such as switchgear to work involving the manufacturer for that reason.
NEMA's guidance lists insulation resistance testing, dielectric absorption testing, and infrared thermography among the evaluation methods. Qualified personnel perform these tests with calibrated instruments and compare the results with the manufacturer's requirements.
Insulation resistance testing applies a DC test voltage to conductors and measures how much current leaks through the insulation. Low readings can indicate moisture or contamination. The results are compared with the manufacturer's requirements and with readings from similar equipment.
Dielectric absorption testing is a time-based insulation test that compares how insulation resistance changes while test voltage remains applied. Moisture and contamination affect that behavior, which makes it useful for judging whether insulation has been compromised.
Infrared thermography uses a thermal camera to find abnormal heat at connections and components. NEMA lists it among the evaluation methods. Because it requires equipment to be energized under load, we use it as a follow-up check once it is safe to restore power.
Treat the room as hazardous until qualified personnel have evaluated it. Do not enter standing water near electrical equipment, and keep people out until power to the area has been confirmed off.
Qualified personnel should isolate power, and the electric utility should be contacted when the service equipment or meter is affected. Staff should not wade into water to operate disconnects. Mission Mechanical coordinates with the utility on service restoration.
Utility-owned equipment, such as the meter and service transformer, is handled by the utility, not by a private electrical contractor. We coordinate with the utility so customer-owned equipment is ready when service is restored.
We confirm the equipment is isolated and safe to approach, inspect it for water lines, silt, and corrosion, document the nameplates and conditions, identify components that must be replaced, involve the manufacturer when reconditioning is considered, test the equipment, complete repairs, and verify the system before restoring power.
The time depends on the number and size of the assemblies, how far the water reached, and what testing is needed. A small panel evaluation is quicker than a large switchgear lineup. We provide a written scope and schedule after the initial survey.
Replacement is the answer when the manufacturer will not recondition the equipment, when internal damage or contamination cannot be corrected, or when parts are obsolete. The decision is documented with its basis, and the authority having jurisdiction may need to be consulted.
Often partly. We plan the sequence of work, and temporary power or phased shutdowns can limit disruption where it is practical. The plan depends on which assemblies serve critical loads and on the utility service arrangement.
Yes. Grounding and bonding connections in the affected area are part of the evaluation, because corrosion and loosened connections may not be visible. See our grounding and bonding systems page for how those connections are inspected and tested.
Yes, if they were exposed to water. Generators, transfer switches, and their controls are part of the electrical system, and equipment that floodwater reached should be evaluated before it is relied on for backup power. We coordinate with the manufacturer or a generator service contractor where needed.
We provide written findings that list each assembly and component, its condition, the tests performed and results, and the decision to replace, recondition, or return to service. Photographs and nameplate information are included.
The report gives your carrier a technical record of what was affected and what the repair scope is. Your carrier and agent decide coverage, so share the documentation with them early and ask whether replaced components should be kept for review.
Replacement of panelboards, switchgear, and service equipment typically requires a permit and inspection through the City of Indianapolis or the applicable local jurisdiction. Mission Mechanical coordinates permitted work and follows the Indiana Electrical Code.
The authority having jurisdiction, usually the local building or electrical inspector, reviews permitted work and decides what is acceptable under the adopted codes. NEMA's guidance advises consulting the authority and the manufacturer when evaluating water-damaged equipment.
Raise or relocate panels, switchgear, and controls above the flood protection level, protect drains and sumps, and write a flood plan. FEMA's guidance states that electrical utilities below the flood protection level must be protected and strongly encourages protecting buildings to at least one foot above the base flood elevation. Local requirements can be higher.
