Web27 Feb 2024 · Here's how you calculate AWG (American Wire Gauge) from the diameter of a wire: Find the ratio (R) of the wire diameter to either 0.005 inches or 0.127 mm. Use the equation n = -39 × log92(R) + 36 to find the AWG number. How do I calculate wire size for distance? The wire size is proportional to the length of the cable distance. Web11 Dec 2008 · A 500 MCM copper conductor is good for 380 amps. If the load is 380 amps or less, then you can use a 500 MCM. If the load is 381 amps or higher, you cannot use a 500 MCM. If you have not calculated the load, and you plan to use a 400 amp overcurrent device to protect a 400 amp panel, then a 500 MCM will not be sufficient. stillwater insurance company pay bill https://mergeentertainment.net
