首先判斷跳閘的空氣開關(guān)是家中配電箱內(nèi)的總開關(guān)還是分路出線開關(guān)。如總開關(guān)未跳閘，只是分路開關(guān)跳閘，則說明大功率電器供電線路接線有問題，即多件大功率電器接在同一分路開關(guān)上，此類情況，將大功率電器線路調(diào)整至負(fù)荷輕的分路開關(guān)即可（建議大功率電器使用單獨(dú)的分路開關(guān)）；如分路開關(guān)沒跳閘，總開關(guān)跳閘，則計(jì)算家用電器功率之和是否超出供電認(rèn)可容量，并檢查總開關(guān)容量是否與供電認(rèn)可容量匹配。如家用電器功率之和超出供電認(rèn)可容量，則減少同時(shí)使用的家用電器數(shù)量（特別是大功率家用電器），并向供電公司申請用電增容；如家用電器功率之和未超出供電認(rèn)可容量，同時(shí)需要提醒的是，部分大功率電器啟動(dòng)電流較大，計(jì)算功率時(shí)應(yīng)考慮啟動(dòng)電流造成的影響。
