View MoreHow to Specify an RV 12V System
Map the system and loads first, then choose protection, controls and hardware that fit the vehicle.
01 / SYSTEM MAP
Map the 12V System and Loads
List the batteries, charging sources and every load: lighting, pumps, fans, refrigerator, heater and outlets. Note steady and startup current for each circuit so switching and protection can be sized correctly.
02 / PROTECTION & CONTROL
Choose Protection, Switching and Monitoring
Plan battery isolation, fuse or breaker protection sized to the wiring, and switch panels for the living area. Add voltage or battery monitoring if users need to see the system state.
03 / INSTALLATION FIT
Confirm Mounting, Cut-outs and Lock Fit
Check panel cut-outs, rear depth and wall thickness for switches and outlets. For locks, confirm lock type, door cut-out, door thickness, handing and keying before you request a quote.
RV & Camper FAQ
A typical house system includes a battery isolation or disconnect switch, a fuse block or distribution panel, switches for living-area loads and charging outlets for devices. Many builds also add a voltage or battery monitor. Share your battery setup and load list, and we can suggest matching product families.
Decide first whether the starting and house batteries must be isolated, combined or selected manually. Then match the switch to the system voltage, continuous and cranking current, terminal size and mounting position. Confirm the switch function against your wiring diagram before ordering.
Selected switch panel platforms support custom symbols, illumination colors and layouts. Send the required functions, panel size and quantity, and feasibility is confirmed during quotation.
RV Hardware covers entry door and compartment lock formats. For replacement, provide the lock type, cut-out dimensions, door thickness and handing, or a photo of the existing lock. For new builds, share the door drawings, quantity and keying requirements.
Each circuit should be protected according to its wiring size and load. A fuse block with separate circuits makes fault finding easier and prevents one failed load from affecting the rest of the system.
