There are two types of stainless steel distribution box according to the use environment: outdoor box and indoor box. Today, Mingya Electric Appliance Co., Ltd. introduces the use and internal production structure of these two kinds of stainless steel distribution boxes. The outdoor stainless steel distribution box, as the name implies, is used outdoors, so the internal structure of the distribution box should be waterproof and rainproof. Generally, after the production of the outdoor distribution box, the distribution box manufacturer will carry out many outdoor rainproof and waterproof tests to achieve the effect of no leakage after the storm, which can be regarded as a qualified outdoor distribution box.

However, the manufacturing core of the indoor stainless steel distribution box is a little different, its internal structure is mainly to consider the problem of dust prevention, so the sealing of the indoor distribution box is better than that of the outdoor distribution box. The indoor stainless steel distribution box is generally made of 201 stainless steel, while the outdoor stainless steel distribution box is generally made of 304 stainless steel because of long-term sun and rain.
