MV Service Disconnect

MV Service Disconnect

MV Service Disconnect

(OP)
In an industrial site where the utility provides a primary metered service - 4 wire grounded wye to a single pad-mount transformer. Is a gang-operated load break switch - pole mounted - suitable to serve as the service disconnecting means? Or is a padmount switch or switchgear lineup required. The utility will be providing metering upstream of this disconnect, on the pole, so no metering compartment required.

Talk to the utility or visit their website. If primary service, most utilities have written requirements for protection, grounding...

"Throughout space there is energy. Is this energy static or kinetic! If static our hopes are in vain; if kinetic — and this we know it is, for certain — then it is a mere question of time when men will succeed in attaching their machinery to the very wheelwork of nature". – Nikola Tesla
