Can The Low-voltage Power Distribution Cabinet Be Placed Against The Wall? What Is The Distance Between The Power Distribution Cabinets?

Requirements for the distance between distribution cabinets and distribution panels:

The operating surface of the switchgear is related to the form of the cabinet and the arrangement of components. It can be wide or narrow, but the depth of the cabinet should be consistent with the entire row of low-voltage cabinets.

The low-voltage power distribution cabinet can be installed against the wall, but it should be in the form of a cabinet that is operated in front of the board and maintained in front of the board.

The two rows of low-voltage power distribution cabinets face each other. Considering the convenience of operation and maintenance, the minimum distance should not be less than 1.8 meters. For the cabinet type for maintenance in front of the panel and behind the panel, the distance from the back to the wall shall not be less than 0.8 meters.

1. When restricted, it refers to the restriction of the building plane and the restriction of local protrusions such as columns in the passage;

2. The operating channel behind the screen refers to the channel that needs to operate the running switch equipment behind the screen;

3. When the screen is arranged back-to-back, the width of the screen front channel can be determined according to the screen front size of the double-row back-to-back arrangement in this table;

4. The minimum width of the passage before and after the control panel, control cabinet and floor-standing power distribution box can be determined according to this table;

5. The width of the operating channel in front of the wall-mounted distribution box should not be less than 1m.

When the wall of the building encounters the partial protruding of the column, the width of the passage at the protruding part can be reduced by 200mm.

1. When the fixed switch cabinet is arranged against the wall, the clear distance between the back of the cabinet and the wall should be greater than the clear distance between the side and the wall should be greater than 200mm;

2. The width of the passageway can be reduced by 200mm when the wall of the building encounters the partial protruding of columns.
