JMC Tested and True

About This Contractor

JMC Tested and True supports mission-critical electrical projects throughout the Silicon Valley region from its San Jose, CA base. Medium- and high-voltage electrical work is among the most critical scopes in any data center, where a single fault can take an entire facility offline. Arc-flash safety analysis and NETA acceptance testing are baseline expectations for data center electrical work, not optional extras. Long lead times on medium-voltage switchgear mean experienced contractors plan procurement early and coordinate closely with the utility. JMC Tested and True carries a 4.9-star rating from 212 reviews.
