nVent ERIFLEX FleXbus Palm Extender can be used for switchboard connection, directly on the LV main protecting device (air circuit breaker or load break switch) or on busbar. nVent ERIFLEX FleXbus Conductor is ready-to-use from one side with direct connection to busbar or circuit breaker palm. However, optional extenders are available for more connection possibilities. If the busbars have several bars per phase, the connection points must be distributed over the various bars of the same phase. This can be achieved by using copper plates (FleXbus Palm Extender) between copper bars or if possible, the nVent ERIFLEX FleXbus Advanced between two copper bars. This installation will guarantee a good repartition of current in the busbar.
