A 320/400 amp meter feeds (2) 200 amp main breaker service panels(grouped together), in a commercial bldg. 240v single phase.
Calculated load of building = 308 amps. Load on each panel less than 180 amps.
Can each main breaker panel be fed with 4/0 AL USE/RHW per 240.4(B)? Terminations are 75 degrees.
