【拡散希望】電気屋さんからの忠告!です。 ただ今地震で停電している地帯の方はブレーカーを全て落として下さい。通電されたら小さなブレーカーを一つづつ入れて下さい。漏電ブレーカーが落ちるようでしたら、無理に入れず、電気事業者等に連絡をとって下さい。漏電による火災を防ぎましょう。

Please RT! Advice from electrician: Please shut off the circuit breaker if you're in an area that had power cut off. When the power is back, turn on one by one using the small circuit breakers. If the short-circuit continues, don’t force it, just contact any electric shop for assistance. Try to avoid fire caused by leakage of electricity.
