I've done lots of things professionally; Life and Health Insurance, Funeral Insurance/cemetery plots.
But what I do now combines all of my jobs I had before I got into insurance; Cabinetry, high-end stereo installation, computer networking, machinist (lathe/mill operator), etc.
I work for a company here in San Diego that builds police cars, fire apparatus, utility vehicles, mission critical electrical and networking systems, and some gov't agency specialty vehicles (surveillance vans, stingray systems, license plate recognition platforms). I love what I do!

300 Amp power distribution
The batteries that feed that distribution (almost 5000 amps worth!

)
Unattended long-term system power (for ALPR systems)
Specialty Cabinet for SRT teams
Needless to say, I'm a bit OCD when it comes to wiring and cabinets.
