I just added how busbars are great components when it comes to electrical power grid because they help reduce corona effects.


I removed the stub notice - IMO there is not much more to be said about busbars. 19:25, 13 Nov 2004 (UTC)

May I ask why on earth it is spelt "busbar" in this article?? And why "copperbar steel bar round bar square bar" and for example "circuit breaker" aren't spelt the same way? The word “bus” comes from a shortened version of “omnibus”, the Latin word that roughly means “all in one”, thus in books, a lot of books in one, or in the electrical application, a lot of electrical “pathways” of currents in one. The word bus is, therefore, a description of the bar, and just like COPPER BAR, ROUND BAR, SQUARE BAR, etc., should be spelt apart.

How about explaining what an "Earth Busbar" is? Nekkensj 16:43, 6 June 2006 (UTC)

Added a link to Ground and neutral. Or it might be possible Earthing system. 12:42, 5 September 2006 (UTC)

It's alright explaining what they are, they're construction and the fact that they carry current but WHY are they used? Protection? For what? How do they compare in operation and function to a typical circuit breaker and what dis/advantages do they have over them.

Will THREE complaints do any good? There are 2 comments directly above, one almost 3 YEARS OLD, noting this article doesn't say one single thing about what busbars DO. We're not ALL EE's - and I SERIOUSLY doubt many EE's are coming here looking for this info! And sorry, I don't read Hebrew, either. This article is a waste of perfectly good electrons. Pun FULLY intended. Grndrush (talk) 00:49, 16 April 2009 (UTC)

A busbar is a wire, no more, no less. It has an enormously higher cross-sectional area than "normal" wire because it is intended to carry enormously higher currents, such as the electrical requirements of an entire (large, eg skyscraper) building. Most but not all wires are insulated, most but not all busbars are not. Nibios (talk) 12:59, 14 April 2010 (UTC)
Excellent reply and I might expand that they are not insulated due to the fact that they need to dissipate a lot of heat and typically are so mechanically rigid and fixed in place that they cannot move about to touch anything else. Ken (talk) 14:54, 24 July 2014 (UTC)

Busbar in Hebrew is "Pas Tsvira" (- "accumulation line"), how to add the link to "in other languages"?[edit]

Why is it called a "busbar"?[edit]

Could anyone explain the name "busbar" itself? It doesn't seem to be either a bus or a bar (apparently being either a flat strip or hollow pipe), and yet no one says that. Names that are difficult to match with the object create uncertainty, and I confess the name "busbar" has puzzled me for years. It still makes me feel there must be something about a busbar that I have not understood, even though on the face of it the article is describing a very simple thing. The name "bus" gives me the impression that the electricity is being routed along various paths in some sort of directed, sequential way, like a bus carrying passengers along a route, dropping some off here and picking others up there. How an undifferentiated strip of metal could do that I cannot see (it looks from the photo as if all the electricity is available at all points equally), but the name continues to make me think it does. After all, there are things that do that in computer networks (the word "bus" is common in computing also), so my mind continues to wonder if that is what a busbar is. And then the name "bar" suggests something solid whose cross section is at least approximately square or round, whereas it appears to be flat or hollow. We are all etymologists at heart and like to understand the connections between words. But as far as I can see there are no connections between the name "busbar" and the object itself. Am I right?

I'm curious too! Kris Huang (talk) 08:10, 3 May 2010 (UTC)
UBJ 43X described a bus as: "dropping some off here and picking others up there.." which is a good analogy for a busbar. If you think of electricity as the bus passengers it is quite accurate as a busbar can often be tapped to 'drop off' passengers/electricity anywhere along its length/route. But specifically, a 'bus' in the electrical sense can refer to the path the busbar takes, or to the portion of the circuit facilitated by the parts functioning as the bus. The bar is likely a simple carryover from when busbars were, in fact, solid. That they are now more often tubes doesn't warrant a new term 'bus tube'. Often the reason they are large tubes is more for the rigidity factor. A suitable solid bar would weight much more and cost much more than a larger diameter tube, and the tube being larger is stiffer and less likely to bend out of position. hope this helps.

Someone has very kindly and helpfully now added the first clear explanation I have ever seen: "The term busbar is derived from the Latin word omnibus[citation needed], which translates into English as "for all", indicating that a busbar carries all of the currents in a particular system." Well done, whoever added that, and thank you. Isn't it nice when you understand something at last.UBJ 43X (talk) 14:42, 30 November 2019 (UTC)

Busbar in The Sims 2[edit]

There is an object in The Sims 2, the Bachman Busbar. It is used to serve drinks to guests and household members. Would make a nice "In Popular Culture" section :) —Preceding unsigned comment added by (talk) 17:25, 28 January 2011 (UTC)

BusbarBus Bar – It would seem that the correct name is "bus bar" two words. As this is noted on the page itself it doesn't make sense for the page title to be "busbar". --Shanee753 (talk) 22:54, 6 August 2012 (UTC)

Oppose. IEEE Std. 100 spells it "busbar", as does American Electricians Handbook 11th Edition, and B.M. Weedy "Electric Power Systems Second Edition" page 5. --Wtshymanski (talk) 23:28, 6 August 2012 (UTC)
