-Busbars are an essential component of electrical systems as they allow safe and easy [[Special:MyLanguage/Series and parallel|parallel connections]] of circuits. There are many different designs of busbars that all serve this same purpose. It is important any busbar used is rated to handle the current that it must carry, and that the busbar is properly isolated from all other system components. Busbars should only be installed within enclosures that are protected from unauthorized or accidental access as they have live exposed parts.
