We have a 460V service that is sole source for a deep well pump. The service is cold sequenced with a Heavy Duty, 600V, 3 pole, 60A fused, 3R disconnect switch that has 200K AIC class R fuses and has a service equipment listing. This disconnect is required by the Utility and becomes Utility owned once energized. This feeds a meter which originally fed a 3R, NEMA 12 pump panel. The pump panel has a fused disconnect with Class J fuses that are also 200K AIC rated. The pump panel does not have a Service Equipment listing as there is no neutral or one needed as the pump motor is 3 phase 460V. This was rejected by the AHJ since the pump panel is not listed as Service Equipment. The available fault current is below 20,000 amps. What is the purpose of 230.66 and why is this a code violation?
