“Draw a campervan electrical system single line diagram with a 16 A 230 V shore hookup, 30 mA Type A RCD, 16 A AC main MCB, 2000 W 12 V inverter charger, 300 Ah LiFePO4 house battery, AC consumer unit, and protected outlets, water heater, fridge, and lighting.”
Die dahinterstehenden Entscheidungen verstehen.
A 30 mA Type A RCD and 16 A MCB protect the campsite AC input.
A transfer switch selects shore power or inverter output.
A Class-T fuse protects the 300 Ah LiFePO4 battery connection.
Outlets and water heater have individual MCBs.
Fridge and LED lighting have separate fuses on the 12 V bus.
Use this for a 12 V campervan that combines campsite hookup with an inverter charger. Final RCD, earthing, cable, and appliance requirements depend on the vehicle and jurisdiction.
Häufige Fragen
Why is there a transfer switch?
It prevents the shore input and inverter output from energizing the AC bus at the same time.
What does the inverter charger do?
It converts battery DC to AC when off-grid and charges the house battery from shore power.
Why use a Class-T battery fuse?
It is a high-interrupting-capacity fuse commonly used near high-current battery sources.
