I have installed a 7 1/2 ton split system air conditioning unit in an electrical/communication room. It is 460 V 3 phase. According to the UMC I need to have a 30" X 30" clear access for where the power is tied into the unit and for controls. I have an inspector who is saying that I must go by the NEC and have 30" X 42" clear access, due to the voltage. Can you help me out.
Thanks
