What size electrical distribution box should be installed on the ground
It takes the incoming power and safely distributes it to different circuits throughout your building. 1) When the distribution box is installed on the wall, it should be fixed with split bolts (expansion bolts). The length of the bolts is generally the sum of the embedded depth (75-150 mm), the thickness of the box bottom plate, the thickness of the nuts and washers, plus the "overhanging. If they need to be placed outdoors, especially in high humidity, you must ensure their waterproofness. 7 meters) high makes it easily accessible without the need to bend or stretch excessively.
