Electrical System
The electrical system powers every major component of the CTC build, from 12V lighting and water pumps to 120V appliances like the washer/dryer, refrigerator, and hot water heater.
This section brings together all electrical documentation — master plans, room‑specific wiring layouts, load charts, and installation notes — into one central hub.
Electrical Master Plan
The Electrical Master Plan provides a high‑level overview of the entire system, including 12V DC and 120V AC distribution, panel locations, circuit planning, grounding, safety systems, and routing strategies.
This is the best place to start if you want to understand how the electrical system works as a whole.
Kitchen Electrical Plan
The kitchen includes multiple electrical components: refrigerator, stove ignition, induction cooktop, lighting, range hood, and the Blueridge indoor air handler.
The Kitchen Electrical Plan documents all circuits, wiring paths, load considerations, and safety requirements for this area.

Bathroom Electrical Plan
The bathroom integrates both 12V and 120V systems, including the water pump, roof exhaust fan, lighting, composting toilet fan, washer/dryer combo, and GFCI‑protected outlets.
The Bathroom Electrical Plan details circuit assignments, routing, safety systems, and shore‑power‑only appliances.

Load Charts
Load charts provide estimated and actual electrical loads for each device in the kitchen and bathroom.
These charts help with circuit balancing, wire sizing, fuse selection, and inverter/shore‑power planning.
System Overview
The electrical system is divided into two major subsystems:
- 12V DC System — lighting, fans, water pump, toilet fan, control circuits
- 120V AC System — refrigerator, washer/dryer, hot water heater, outlets
Both systems originate from the main distribution panels and are routed through protected channels throughout the trailer.
Safety & Standards
Electrical safety is a core part of the build. All electrical documentation follows these principles:
- GFCI protection in wet areas
- Proper grounding and bonding
- Correct wire gauge for each circuit
- Dedicated circuits for high‑draw appliances
- Clear labeling at both panel and device ends
- Protected routing away from plumbing lines

How This Section Evolves
As the build progresses, the Electrical System section will expand with updated diagrams, installation photos, circuit revisions, and final load measurements.
This page is designed to serve as the long‑term reference hub for all electrical work in the trailer.
