Did you seen it somewhere?phinds said:but who says it isn't
The fact that you haven't seen it sold that way is irrelevant. I asked you where you heard that it can't be done and you are ignoring the question. On this forum that is not acceptable. When you are asked to provide a source for a categorical statement the rules say you have to provide it. You said it isn't practiced. Give me a source that says it isn't practiced.Ivan001 said:Did you seen it somewhere?
You can everywhere buy horizontal, vertical or stair type of busbar insulators, but nowhere something like that. I guess that those red insulators have low mechanical strenght in regards to short circuit power between two bars. I asked it because I always see three phases placed horizontaly with some spacing between phases, but never seen one above other..
OK, I understand.phinds said:Give me a source
Yeah of course. In that case, can you give explanation why we can use one busbar above other or why we can't. Is insulator's strenght too week for this type of arangement or not?phinds said:Absence of evidence is not evidence of absence. You continue to evade the question.

Convection cooling is improved by mounting the bars on their sides. Better cooling reduces the need for copper and support for that mass.Ivan001 said:Why it's not a practice to use such busbar spacing insulator arrangement as it's showed in the picture from attachment (one busbar above other)?
Well said, thanks.Baluncore said:How many other reasons do you need?
Busbar spacing refers to the distance between two adjacent busbars in an electrical system. It is important because it affects the overall performance and safety of the system. Proper spacing ensures efficient power distribution and reduces the risk of electrical faults and failures.
Stacking busbars means placing them on top of each other instead of having them side by side. This is not recommended because it can lead to overheating and uneven distribution of current. It also makes it difficult to inspect and maintain the busbars.
No, busbars should not be stacked in any situation. It is only recommended in specific cases where the design and installation have been carefully planned and approved by a qualified engineer. Stacking should be avoided whenever possible.
Stacking busbars can lead to overheating, which can cause damage to the busbars and other components in the system. It can also create uneven distribution of current, which can result in power disruptions or even electrical fires. Additionally, it can make it difficult to maintain and inspect the busbars, increasing the risk of electrical hazards.
Yes, there are several alternatives to stacking busbars. One option is to use larger busbars to accommodate the required current. Another option is to use parallel busbars, which involves having multiple smaller busbars connected in parallel to handle higher currents. It is always best to consult a qualified engineer to determine the most suitable alternative for your specific situation.
