For more than 30 years, electrical equipment manufacturers have developed some very attractive busbar and distribution systems (standard busbar profiles & sizes, busbar supports, comb busbar, distribution systems & accessories) to distribute power inside these electrical equipments in an easy and safe way, especially when they are type-tested.
As far as I see it a lot of panel builder use partially or totally these busbar systems …

When professionals want to manage an electrical system in a new installation or after retrofit or extension of an existing installation, it is important to consider the Harmonic currents emitted by the non linear loads connected to the distribution system.
The non linear loads or products producing harmonics can be as example, for industrial equipments: welding machines, battery chargers, variable speed drives for electrical motors, uninterruptible power supplies, or for office equipments or household appliances: TV sets, fluorescent lighting, light dimmers, etc…
