JAAM Electric, a C-10 electrical and low-voltage contractor operating from Isaac Street in Santee, provides commercial wiring and power-distribution services for Southern California's major construction builders. Large-scale photovoltaic interconnections on commercial rooftops require the same conduit-and-panel expertise that solar specialists including Jamar Power Systems on Prospect Avenue rely on for grid-tied system commissioning. The firm's scope covers new-construction electrical rough-in, tenant-improvement power upgrades, and facility-level medium-voltage distribution for healthcare, education, and multi-family projects. Low-voltage divisions handle structured cabling, fire-alarm circuits, and access-control wiring—systems that overlap with the general electrical infrastructure serviced by Keil Electric on Magnolia Avenue. Highest-capacity installations involve 2,000-amp switchgear assemblies with arc-flash labeling to NFPA 70E standards and Section 240 coordination studies for selective breaker tripping.
