災害と停電　Natural disasters and power outages

大きな自然災害時には停電を伴うことが多い。我家では万が一に備えて家全体への電源供給経路を商用電源から蓄電地／発電機電源に切替できるようにすでに工事を済ませています。
The major natural disasters are often with the power failures. So in our house, we have already finished the electrical work to change the power source from the commercial power to the one by the batteries or the generator against a rainy day.
