Your home's safety depends on knowing when a distribution board is overloaded. A buzzing noise or a burning smell from outlets means. Each piece of electrical equipment on a distribution system has a probability of failing. When first installed, a piece of equipment can fail due to poor manufacturing, damage during shipping, or improper installation. The distribution station area is composed of distribution transformer, low-voltage comprehensive distribution box, lowvoltage line, drop out fuse and other medium voltage protection equipment. It's typically a gray metal box tucked away in a basement, garage, or utility closet.
