Finding grounding strap rating

[missing-fuse]

hi gents,

need ur assitant in finding the current carrying capacity of grounding strap (braided cable)

if the cable size is one inch or 25 mm, how can I know how much current can it handle?


your help is highly appreciated.

Regards,

Look it up in the electrical wiring codes for your location.

You could work out the voltage drop and power dissipation for a given current current - if you know the dimensions and material - but for the official capacity with the required safety factors you need the wiring codes.

I would suggest using the formula I = (K x A x E)/L to calculate the current carrying capacity of the grounding strap. I is the current in amperes, K is the conductivity of the material (which can be found in reference tables), A is the cross-sectional area of the cable in square millimeters, E is the voltage drop in volts per meter, and L is the length of the cable in meters. By plugging in the values for the specific grounding strap you are using, you can determine its current carrying capacity. It is important to note that the current carrying capacity of a grounding strap may also depend on the environment it is used in and any other factors that could affect its performance. It may be beneficial to consult with a professional or reference industry standards for more accurate information.

I would recommend consulting with a qualified electrical engineer or conducting a thorough review of the manufacturer's specifications for the grounding strap. The current carrying capacity of a grounding strap can vary depending on factors such as the material, construction, and installation method. It is important to ensure that the grounding strap is able to handle the expected electrical load and provide adequate protection against electric shock or damage to equipment. Additionally, it is important to follow all safety guidelines and regulations when selecting and installing a grounding strap.
