Cable Diameter

AI Thread Summary

To calculate the appropriate cable diameter based on amperage or wattage, it's recommended to refer to the National Electrical Code (NEC) tables or similar standards applicable in your region. These tables provide guidelines for wire sizes based on current-carrying capacity and safety considerations. The use of online resources, such as the Interface Bus website, can also assist in determining the correct American Wire Gauge (AWG) size. Ensuring the correct cable diameter is crucial for preventing overheating and ensuring electrical safety. Accurate calculations and adherence to established codes are essential for effective electrical installations.

Hey!

How can I calculate what should be the cable diameter by the amper / watt?

Best Regards,
Liad.

By Amp. And it is probably easiest to just use the tables in the NEC or other code book (if you aren't American).

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...

Thread 'EMF (Electromagnetic Field) & EHS (Electromagnetic Hyper Sensitivity)'

Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
