Have you spent the resources to seal your electrical system at the devices only to leave the job unfinished? With traditional bus bars you have done just that. They have many individual connections which can be prone to failure. They have exposed copper plates that may have tin plating protection or none at all. These plates will corrode which will require replacement. Sure there are sprays that will slow the corrosion down, but it will not address the root causeexposed metal. The Sealed Bus Bar encapsulates the conductive plate copper leaving the only exposed metal the stainless studs for the connections to the battery.
