ELECTRICAL EVENTS CAN CAUSE “INVISIBLE” DAMAGE — AND LONG, EXPENSIVE DOWNTIME
Why Power Quality & ESD Are High-Severity Risks in Electronics Manufacturing
Electronics and technology manufacturing relies on stable power and controlled environments. A power surge, transient spike, brownout, phase imbalance or an upstream switching event can damage sensitive test equipment, production machinery, servers, control systems and in-process assemblies. Even when equipment keeps running, electrical stress can create latent faults that surface later as yield loss, warranty issues or costly troubleshooting.
Electrostatic discharge (ESD) is a second major loss driver. ESD events can damage components during handling, assembly, test and packaging — especially where controls degrade over time (worn wrist straps, poor grounding, damaged flooring, incorrect humidity, or process drift). ESD damage can be “hard failures” or latent defects that pass test but fail in the field, making root cause difficult and increasing liability exposure.
Insure24 helps electronics and technology manufacturers structure insurance around these risks — typically by aligning property, engineering breakdown, stock/WIP, and business interruption cover with the reality of power quality events and ESD loss patterns.
WHAT POWER SURGE & ELECTRICAL DAMAGE COVER CAN INCLUDE
The Goal: Cover That Matches the Real Failure Mode
Power surge losses are often classed as electrical/mechanical breakdown rather than “fire” or “storm”. ESD losses can look like quality issues unless you can evidence a defined event and affected batches. We help structure cover and documentation so incidents are presented clearly and the policy responds as expected.
Common Power Surge, ESD & Electrical Damage Loss Scenarios
These are typical scenarios we see across electronics manufacturing, test environments, panel building and technology assembly operations. Underwriters will consider how often power events occur in your area, how resilient your electrical infrastructure is, and how you control ESD in handling and assembly.
Power Quality & Electrical Event Scenarios
- Transient surge damages SMT equipment controls, PLCs or drives
- Brownout causes unstable test readings and scrap/retest of batches
- Utility switching event damages UPS, servers or network infrastructure
- Lightning-related surge damages power supplies and instrumentation
- Generator/UPS changeover event causes equipment faults
- Phase imbalance overheats motors and damages compressors/chillers
- Failure of surge protection devices (SPDs) leads to widespread damage
ESD & Handling Damage Scenarios
- ESD control failure damages ICs during manual assembly or rework
- Wrist strap / grounding faults create latent defects in batches
- Humidity drift increases ESD risk and component damage
- Poor packaging or non-ESD bags lead to transit/handling damage
- ESD floor degradation reduces grounding effectiveness over time
- Tooling/fixtures build static charge causing repeated component failures
- Latent ESD damage leads to field failures and warranty escalation
How Insurance Can Be Structured for Electrical Damage & ESD Risk
The correct structure depends on what is being protected (equipment vs stock vs output), how losses typically occur, and how your site is configured. Power surge events often sit under engineering breakdown / machinery breakdown sections. Stock/WIP losses may sit under property, stock or specialist extensions. Business interruption should align with the correct trigger, not just fire/flood.
ESD losses can be more complex because they may appear as “quality issues”. Where possible, we focus on underwriting clarity: your ESD programme, traceability, and the ability to identify affected lots and demonstrate a defined incident.
Property & Engineering Breakdown
- Damage to machinery controls, drives, PLCs, test rigs and instrumentation
- Coverage for sudden electrical/mechanical breakdown (wording dependent)
- Spare parts and expediting costs (where included)
- Temporary equipment hire (extra expense) to reduce downtime
- Cover for critical building services affected by electrical events
- Alignment with BI triggers (see below)
Stock, WIP & Deterioration Extensions
- Damage to in-process assemblies and sensitive components
- Cover for stock stored under controlled humidity/temperature
- Deterioration of stock where environmental control fails (where applicable)
- Customer-owned goods and consigned stock (if declared)
- Rework and retest costs (where insurable and covered)
- Evidence-based claims supported by traceability and batch control
Business Interruption (BI) Alignment
- Downtime after equipment damage from surge events
- Loss of output while test rigs or production lines are repaired
- Increased cost of working to maintain deliveries
- Correct indemnity period to reflect lead times and requalification
- Ensuring BI is triggered by the same events you’re likely to suffer
Liability Considerations (Field Failures)
- Products liability for injury/property damage caused by defective products
- Product recall/rectification options if ESD/defect requires action at scale
- PI/Tech E&O where failure relates to design/specification responsibility
- Contract risk management and limitation of liability review
- Traceability and QA processes improve defence and claims outcomes
What Underwriters Look For: Power Resilience & ESD Controls
Insurers price electrical damage risk based on how resilient your site is and how disciplined your controls are. Demonstrating a structured approach to power protection, maintenance and ESD governance improves underwriting confidence and can improve terms.
Power Protection & Electrical Infrastructure
- Surge protection devices (SPDs) and inspection/maintenance regime
- UPS coverage for critical loads and monitoring/alarm configuration
- Generator availability, testing and changeover procedures
- Power conditioning for sensitive test equipment (where used)
- Electrical maintenance logs and thermographic inspection (where applicable)
- Segregation of critical circuits and protection coordination
- Incident logs for power events and corrective actions taken
ESD Programme & QA Discipline
- ESD policies, training and regular audits
- Grounding checks for wrist straps, benches and tooling
- ESD floor testing and lifecycle replacement planning
- Humidity control strategy and monitoring
- ESD packaging standards for internal movement and shipping
- Traceability (lots, batches, serialisation) to isolate affected goods
- Failure analysis process for suspected ESD events
A power event took out a critical test rig and threatened delivery commitments. Insure24 helped align engineering and BI cover so downtime was handled properly.

FREQUENTLY ASKED QUESTIONS
+-
Does property insurance cover damage from power surges?
Sometimes, but many surge-related losses are treated as electrical/mechanical breakdown rather than a standard “insured peril” like fire. Engineering /
machinery breakdown cover is often the key section for sudden electrical failure, subject to the wording and any exclusions or conditions.
+-
Can business interruption cover downtime after an electrical event?
Yes, but BI needs to be aligned to the same trigger that causes the damage (for example, engineering breakdown). If BI is only linked to fire/flood perils,
it may not respond to the most common electrical damage scenarios. We help structure BI so it matches your real downtime risks.
+-
Does insurance cover ESD damage to components and assemblies?
Coverage depends on the wording and how the loss is evidenced. ESD can present as a quality/yield issue unless you can identify affected batches and a
defined incident. Strong traceability and an ESD programme help support claims and underwriting.
+-
What equipment is most vulnerable to power quality events?
Common vulnerable assets include PLCs and drives, SMT line controls, reflow ovens, AOI/X-ray systems, test rigs, servers and network equipment, power
supplies, and critical building services such as chillers and compressors. The risk is higher where there are single points of failure without redundancy.
+-
How can we reduce premiums for electrical damage risk?
Improving power resilience (SPDs, UPS coverage, monitoring), maintaining electrical systems, documenting event history and corrective actions, and running a
robust ESD programme (audits, grounding checks, humidity control and training) typically improves underwriting confidence and can help pricing.
+-
How quickly can Insure24 provide a quote?
We can often provide an initial indication quickly. Tailored quotations are typically arranged once we’ve reviewed your equipment values, power resilience,
ESD controls, BI exposure and any claims history.
