Our Diagnostic Methods & Tools
| Tool/Method | Purpose | When We Use It |
|---|---|---|
| Infrared (IR) Thermography | Detect hot spots at connections and gear | Panels, switchgear, MCCs, high‑load circuits |
| Insulation Resistance (Megger) | Evaluate conductor/coil insulation health | Wet/damaged circuits, motors, long runs |
| Power Quality Logging | Record voltage, current, THD, dips/sags | Flicker, VFD issues, nuisance trips, sensitive equipment |
| Circuit Tracing & Toners | Locate hidden junctions and mislabeled runs | Renovations, unknown circuits |
| Grounding/Bonding Tests | Confirm safe fault clearing paths | Shock complaints, metallic piping tie‑ins |
| Clamp Meters/Inrush | Measure load and motor start current | Breaker sizing, motor starts, compressor loads |
Residential Diagnostics
Keep your home safe and comfortable with targeted troubleshooting that solves problems—not symptoms.
Typical Issues Resolved:
- Tripping GFCI/AFCI in kitchens, baths, garages, and exteriors
- Outlets that feel warm or intermittently lose power
- Panel hot spots and buzzing noises
- Lighting flicker from loose neutrals or shared circuits
- Surge protection evaluation and upgrades
What You Can Expect: a clean workspace, clear explanations, and repairs performed to NEC standards with quality parts.
Commercial Diagnostics
Electrical reliability drives revenue and customer experience. We diagnose with minimal disruption—often after hours—to keep your operations moving.
We Troubleshoot:
- POS, refrigeration, and kitchen circuits
- Office power, lighting controls, and conference room AV circuits
- Data closet power, UPS interfaces (owner‑provided UPS), and grounding
- Exit/egress lighting failures and emergency power anomalies
Deliverables: a prioritized punch list, pricing for corrective actions, and documentation for facility records.
Industrial Troubleshooting
Production environments demand speed and precision. Our industrial electricians work safely around live systems and coordinate with supervisors to protect throughput.
Focus Areas:
- MCC buckets, starters, VFDs, and motor circuits
- Control wiring faults, I/O misreads, and sensor noise
- Harmonics/THD issues causing nuisance trips and overheating
- Phase imbalance and voltage drop on long feeders
- Conveyor and process equipment faults tied to sequencing and interlocks
Approach: verify symptoms with operators → use IR/power logging → isolate → correct → commission under load.
Power Quality Audits
Poor power quality shortens equipment life and causes intermittent faults. We log and analyze:
| Metric | Impact | Remedies |
|---|---|---|
| Voltage Imbalance | Motor overheating, vibration | Phase rebalancing, transformer taps |
| Harmonics (THD) | VFD/transformer heating, control glitches | Line reactors, filters, multi‑pulse drives |
| Sags/Swells | PLC resets, lighting flicker | Tap changes, dedicated circuits, UPS for controls |
| Inrush/Starting kVA | Nuisance trips, dimming | Soft starters, VFD sequencing, larger feeders |
We provide a written report with charts and corrective options aligned to your facility’s priorities.
Grounding & Bonding Verification
Reliable fault clearing protects people and equipment. We test grounding electrode systems, bonding jumpers, and metallic piping bonds to eliminate objectionable current paths and shock risk. Corrections include proper bonding, neutral isolation where required, and labeling for maintenance clarity.
Safety Protocols
Diagnostics often occur near energized equipment. Our crews follow:
- NFPA 70E arc‑flash boundaries and PPE
- LOTO procedures and energized work permits where applicable
- OSHA‑aligned housekeeping, barricading, and signage
- Manufacturer torque specs and test instrument calibration standards
We will not energize equipment that remains unsafe—period.
The Legacy Diagnostics Process
- Interview & Symptom MapDocument when/where the problem occurs, affected devices, and operational context.
- Visual & Safety ChecksLook for discoloration, damage, incorrect labeling, or obvious hazards; secure the area.
- Targeted TestingChoose the right tools (IR, Megger, logger, tracer) to isolate the fault quickly and safely.
- Corrective ActionMake on‑the‑spot repairs when feasible; otherwise, provide clear options and timelines.
- Verification Under LoadMeasure performance after repair to confirm stability and code compliance.
- Report & RecommendationsDeliver a concise summary with readings, photos, and next steps (preventive options, upgrades).
Device & Circuit Repairs
- Replace damaged breakers, switches, outlets, and GFCI/AFCI
- Re‑terminate and torque lugs; correct back‑stabbed connections
