What Electrical Installation and Service Corporation does

Electrical Installation and Service Corporation (EISEC) is a Puerto Rico-headquartered engineering and technical power services company founded in 1972 by Ramón E. León Cansobre. The firm provides specialized electrical power equipment, testing, and maintenance services to commercial and industrial clients across Puerto Rico and the broader Caribbean, including the US Virgin Islands, St. Martin, St. Lucia, Antigua, Barbados, Anguilla, the Dominican Republic, and the British Virgin Islands.

EISEC's offering combines hardware distribution with technical services. Hardware includes power transformers (sale and rental), automatic transfer switches, low/medium/high voltage breakers, emergency generators, protection and metering equipment, and — through a distribution partnership with Alltec (USA) — surge suppressors, grounding systems, and lightning protection. Services span preventive maintenance testing compliant with PREPA/LUMA reference statement AEE 03-01, SKM-certified arc flash and short circuit coordination studies, power quality monitoring, infrared thermal surveys, transformer oil testing/degasifying/vacuum filling, breaker testing and reconditioning, and 24/7 on-call emergency restoration via a mobile laboratory. The firm holds NETA certification and emphasizes a "Facility Protection Program" spanning residential to commercial applications.

The business model is a hybrid of hardware sales/rental and professional services, priced via custom quotation with multi-year maintenance contract cadence. Go-to-market is direct enterprise field sales targeting private industry, federal and state institutions, and manufacturing operations, with no public pricing or marketing beyond the company website. EISEC is privately held, founder-operated, with 11-50 employees, no disclosed funding, no parent company, and no identified subsidiaries. Revenue, customer concentration, and backlog figures are not publicly disclosed.
