Bowtie Engineering provides NETA-standard electrical testing for commercial and industrial facilities nationwide. We perform acceptance testing on new equipment and maintenance testing on existing systems to the standards published by NETA (the InterNational Electrical Testing Association) — including primary injection, relay testing, insulation resistance, and breaker testing. Led by licensed Professional Engineers and delivered through a network of NETA-certified technicians we can deploy across the United States, our testing verifies that your electrical equipment will perform safely and correctly when it matters.
NETA testing is a set of standardized procedures published by the InterNational Electrical Testing Association for commissioning, maintaining, and field-testing electrical power equipment. When equipment is tested to NETA standards, qualified technicians follow a defined, auditable methodology to verify it operates correctly, safely, and within manufacturer and code specifications. It matters because electrical equipment degrades over time — insulation breaks down, breakers fail to trip correctly, connections loosen. Facilities that skip NETA-standard testing are operating on assumptions about equipment condition rather than verified data, increasing the risk of arc flash, equipment failure, and unplanned downtime.
Acceptance testing (NETA ATS) is performed on new or newly-installed equipment before it’s energized, to confirm it was installed correctly and wasn’t damaged in shipping or installation — your last checkpoint before commissioning. Maintenance testing (NETA MTS) is performed on equipment already in service, on a recurring schedule, to catch degradation before it causes a failure. New facility or new gear? You need acceptance testing. Existing facility protecting uptime and NFPA 70B compliance? You need maintenance testing. Bowtie performs both.
Every test is performed to the applicable NETA standard and delivered with auditable records.
NETA-standard testing anywhere in the U.S.
Bowtie can deploy NETA-certified technicians across the United States, which means multi-site operators get the same standardized testing methodology and the same documentation format at every location — not a patchwork of local vendors with different standards. For national accounts standardizing their electrical safety and maintenance programs, consistent NETA-standard testing across every site is often the whole point.
NETA testing is one part of a complete maintenance program. Testing tells you the condition of your equipment; a maintenance program acts on it. Most clients run NETA-standard testing inside Bowtie’s broader NFPA 70B electrical maintenance service, so the results feed directly into scheduled maintenance and your compliance records.
Bowtie performs testing to NETA standards and deploys NETA-certified technicians nationwide, but Bowtie is not itself a NETA Accredited Company. Our testing follows NETA methodology and is documented to NETA specifications.
Acceptance testing (ATS) is done on new equipment before energizing; maintenance testing (MTS) is done on in-service equipment on a recurring schedule to catch degradation. Bowtie performs both.
Intervals depend on equipment type, criticality, and environment. NETA and NFPA 70B provide the framework; Bowtie sets your intervals based on your specific equipment and builds them into a recurring program.
Yes. Bowtie performs primary injection testing on low- and medium-voltage circuit breakers and switchgear, along with relay, insulation, and transformer testing — all to NETA standards.
Yes. Bowtie deploys NETA-certified technicians across the U.S. with standardized methodology and documentation, which is ideal for multi-site and national accounts.
Bowtie provides PE-led, NETA-standard electrical testing — acceptance and maintenance testing, primary injection, relay and transformer testing — deliverable nationwide through a network of NETA-certified technicians, with auditable documentation.
