Inverter in the loft. Battery in the garage. 35m of mixed route in between.
Sounds simple β just use armoured cable, right?
Not quite. On the DC side, one cable route actually involves three separate decisions:
πΉ Mechanical protection β does the route need it?
πΉ Insulation β does the wiring system support the DC-side protective measure?
πΉ Earthing β what implications come with the chosen construction?
Armour alone doesn't tick all three boxes. A robust appearance is not the same as the right insulation answer.
