I have a customer-owned 12.47KV overhead line ((3) #2 ASCR), which is primary-metered from the utility, that I need to bring underground to a exterior load interrupter switch to enter the facility and feed an indoor dry-type transformer.
I will be transitioning the overhead feeder to a pole-mounted airbreak switch to an undeground feed using EPR conductors.
Question: Does the EPR conductors require a concentric neutral to act as the grounded service conductor between the overhead line and the load interrupter switch? I plan to install a standard ground from the load-interrupter switch location to the interior of the facility but wanted opinions on how I needed to handle the conductors between the overhead line and load interrupter switch.
Thanks.
