Frequently Asked Questions – Electrical Testing in San Jose
Q1: What types of facilities in San Jose do you typically service?
We work with commercial buildings, data centers, manufacturing plants, utility substations, and municipal infrastructure throughout San Jose and the surrounding Silicon Valley region.
Q2: How often should electrical testing be performed?
That depends on the equipment, environment, and regulatory requirements. For most facilities, annual or biannual testing is standard, but critical systems may require more frequent analysis. We align with NETA and IEEE recommendations.
Q3: Can you test high-voltage and SF6 breakers on-site in San Jose?
Yes. Our field engineers are equipped to test low, medium, and high-voltage circuit breakers—including SF6 units—directly at your facility. We also offer gas analysis and time-travel diagnostics as needed.
Q4: Do you provide documentation for compliance or insurance audits?
Absolutely. Every test includes detailed reports with measurements, findings, and recommendations. These reports meet compliance standards and are accepted by most insurers and regulatory bodies.
Q5: Are your services available after hours or in emergencies?
