Distribution box ni gaw, shanhte a galu kaba ai lam, n-gun n rawng ai, laklai ai hpaji masa, shara langai mi hta n-gun n rawng ai, laklai ai hkrang shapraw ai lam ni, n-gun n rawng ai shara ni hpe lang mai ai lam ni a majaw, laklai ai lam ni nga ai. Shanhte hpe law law lang lang ai, ngang grin ai hte kam mai ai, grai akyu rawng ai, grup yin hpe mung n hkra ai. Shanhte gaw wan n-gun jaw ai line kata na daw amyu myu a lapran n-gun hpe hkrak hkrak garan gachyan na matu hkang zing ai shara hku nna magam gun nga ai. Shanhte gaw upstream power hpe kam mai ai hku hkap la lu na matu hte power hpe load ni hpe hkrak hkrak garan gachyan lu na matu madi shadaw ya ai, power supply quality hpe lang ai ni myit dik lu na matu ahkyak ai. Power garan ai box ni a bungli galaw ai lam hta kam hpa mai ai lam hpe grau kaja hkra galaw na gaw quality engineering a madung yaw shada lam rai nga ai.
Distribution box ni hpe lang nna, n-gun hpe rational hku garan gachyan na matu hte circuit galai shai na matu loi ai. Shanhte gaw madang tsaw ai makawp maga lam hpe jaw ya nna, circuit a conduction status hpe hkam sha lu ai hku madun dan ai.
