what is the difference between busbars and busways?

Busbars and busways are both used to distribute electrical power, but the main difference between

the two is that busbars do not have an enclosure, while busways have a protective enclosure.

Busbars are used to split the electrical supply into separate circuits at one location, while

busways are long busbars with protective covers that allow new circuits to branch off anywhere along the busway.
