The Power company is making me provide the wire from the transformer to a 800 amp switch gear. The calculated load is 395 amps. I was going to pull parallel 500 mcm's based off of 310.16, and 240.4b however there is no overcurrent device. Is there any code reference's that would allow me to do so or would the calculated amperage of my wire have to be 800 amps or more. Thanks
