The 12V system is the backbone of every mobile build. Every light, every fan, every USB port, every appliance that runs directly off your battery bank flows through it. Wire it poorly and you spend years chasing gremlins. Wire it right and you never think about it again.
Voltara Systems designs and installs 12V electrical systems for vans, RVs, boats, and specialty vehicles in Long Beach, CA.
Every circuit starts with overcurrent protection at the source. No exceptions — this is what stands between a wiring fault and a fire.
Wire gauge selected for both amperage and run length. Voltage drop increases with distance — we calculate both before specifying anything.
Often overlooked and almost always underdone on DIY builds. The grounding system is half the circuit — we treat it that way.
Every circuit starts at a fused distribution block or bus bar — properly sized for the load it serves. Wire gauge is selected for both the amperage and the run length. Connections are crimped or soldered correctly, not twisted and taped. Every run is labeled. Nothing is left floating.

Undersized wire on long runs. Voltage drop increases with distance, and wire that's adequate at 3 feet may cause problems at 15 feet. We calculate run length into every wire sizing decision — it's not optional math.
Yes. Every circuit needs overcurrent protection as close to the power source as practical. It's not optional — it's what prevents a wiring fault from starting a fire in your walls.
Yes. We'll assess what's there, identify what needs to be corrected, and either build on it or replace it depending on what we find. Some DIY work is solid; some isn't. We tell you which.
Let's wire it correctly from the start.
