wire diameter for specific loads
wire diameter for specific loads
(OP)
I'm designing a link for a power supply (fail-safe system) and am looking for some information on the cross sectional area of conductors needed to carry the load.
The scenarios I have to design for are as follows:
500VAC at both 60Hz and 400Hz, with 4 different current loads (10A, 20A, 50A, and 100A).
The conductor will be silver plates copper solid wire/bar. Any help to find a equation/calculator to determine the appropriate cross sectional area would be greatly appreciated

Click (CABLING) on left scroll menu
Click (POWER CABLE AMPERAGE) and read on....It has a list of gauge to amps for power design.....hope this helps!

thanks for the link BTW.

For a given power, higher voltage means less current and thus less I*R voltage drop. This is the obvious advantage.
But higher voltage also means that any given I*R voltage drop matters less in proportion to a higher voltage. In other words, a 1kV voltage drop is serious for a 6kV line but it is a non-issue for a 500kV line.
The advantage (in terms of reduced voltage drop) goes up as the square of the voltage (for a given power).
None of this matters in this case.
