A formula for 60 Hz with reasonable ventilation:
Imax = 7.73 x A^0.5 x p^0.39
A is the cross-section area in sq. mm and p is the circumference of the busbar's cross-section in mm.
So for a busbar of 100 mm x 5 mm the maximum current is 1391 amps.
pressure rating up to 40 mm will be 20 bars and higher sizes it will be reduced as PN-15.
Typically copper conductors that provide a phase of electricity.
Because copper is a very good conductor of electricity. Most other metals aren't as good, and would cause more resistance, resulting in the bus bar heating up.
Bus bars are electrical conductors used to distribute power and are characterized by several key parameters, including current-carrying capacity, material (commonly copper or aluminum), cross-sectional area, and temperature rating. The current-carrying capacity determines how much electrical current the bus bar can handle without overheating. Additionally, factors like ambient temperature, installation environment, and required voltage levels can influence the design and selection of bus bars. Proper sizing and material choice are crucial for efficient and safe operation in electrical systems.
to calculate the weight of diffrent dia bars is d2/162 D=dia of bar , and multiply into 2 times then divide it by 162
BARS stands for Behaviorally Anchored Rating Scale.
In World of Warcraft, copper bars can be used in a few ways. It is used in black smithing plans, engineering schematics. jewel crafting designs and also to make copper bars.
Using your smelt skill you get from purchasing mining you smelt the Copper Ore you get into bars at a ratio of 1:1
You make copper bars in the smelting furnace outside the mine,

The amp rating of a panel is based on the size of materials used (the bars, etc). You can pull 400 amps through your panel (provided a 400amp breaker was in place); but it would probably melt down very quickly. Basically you have 100 amps total to play with: be it from two 50amp breakers or 30 subpanels pulling 3 amps. :D You just can't pull more than 100amps at one time or the main will trip. The 100 amps is a rating for each bar. If your panel has a 100 amp double pole breaker, then you can use up to 100 amps on each pole. You really shouldn't draw more than 80 amps continuously. But you can count on having that 160 amps avilable if all your loads use only one hot leg of the panel (120 volt loads instead of 240).
That depends on the weight of the bars. One half pound bar of copper is approximately four dollars, so two bars, weighing one pound, will be close to eight dollars.
BARS (Behaviorally Anchored Rating Scale) and the Graphic Rating Scale are both performance evaluation tools, but they differ in their approach. BARS incorporates specific behavioral examples to anchor each rating point, providing clear criteria for evaluation and enhancing objectivity. In contrast, the Graphic Rating Scale uses a continuum (e.g., 1 to 5) without specific behavioral anchors, which can lead to more subjective interpretations. Thus, BARS tends to offer more precise feedback, while the Graphic Rating Scale is simpler and quicker to administer.
Copper as a metal is mined from copper nodes by miners; in order to buy it, you'd have to check the Auction House, where the miners then sell their copper. Copper can be sold as either ore, or as copper bars.
although this is not a chemistry question I do have an answer for you. A motor with copper bars is classified as a shaded pole motor. They are low torque motors and do not require any capacitors for run or start functions. hope that helped
