Please email on current carrying capacity

Thank you

Dear Sir,

I'm a new member of CR4 and I was interested in this table of current carrying capacity. I tryied to read the contents and it was not possible due to poor resolution.

Could you please help me to send me a copy that is readable.

Thank you.

Can you give me an e-mail address please?

Hi Peterd,

I am not the original enquirer but would be pleased if you could send it to me also.

Please send a copy ( current carrying capacity ) to me.

peterd,

can you please send me a readable copy of this to my email add: reyaddun@yahoo.com

Many thanks!!

Current carrying capacity is sort of a subjective thing. If you want to know the ultimate current-carrying capacity of anything, then it gets quite complicated, as the bus bar thermodynamics come into play.

If you want to know current-carrying capacity of bus bars according to the governing authority in your area, then you'll need to know what "standards" they use, such as International Electrical Code, etc.

The calculations require you to know material resistivity or permittivity (reciprocal of impedance). V = IR, P = I²R, E = Pt. Temperature rise under worst-case conditions will dictate busbar size given no regulating authority. 40^oC rise above ambient temperature is a typical, allowable temperature rise. The calculated temperature rise does require you to use thermodynamics.
