Can someone provide me with or point me to the recommended phase to phase and phase to ground clearances for the uninsultated bussing in 15 KV gear to be used with an ungrounded Delta service? - Thanks

I would look in ANSI C37 standards for metal-clad switchgear. At 15 kV, I don't think ungrounded versus grounded will have any impact on the necessary phase spacing.
