IP of panel, Forms of seperation of panels

Question

Accepted Answer

The IP rating of a panel refers to its level of protection against solids and liquids. Panels can be separated by physical barriers or electrical insulation.

IP rating indicates the degree of protection provided by a panel against dust and water. Higher IP ratings offer better protection.
Separation of panels can be achieved through physical barriers such as walls, partitions, or enclosures.
Electrical insulation is another form of separation, where panels are isolated from each other using insulating materials or techniques.
Examples of physical separation include using separate rooms for different panels or installing individual enclosures for each panel.
Examples of electrical separation include using insulating materials like rubber gaskets or insulating coatings on panel surfaces.
Proper separation of panels is important to prevent cross-contamination, electrical interference, and ensure safety in electrical systems.

Accepted Answer

IP of panels means ingress protection of panels, IP of panels shall be finalised considering area where panels installed.

Forms of separation of panels means protection given to single feeder for eg form-4b means circuit breakers and busbar shall be isolated from each other.
