[Ebkelectric]

Hi guys I have 3 phase transformer

Secondary 208Y/120

KVA:45
PRI (H) VOLTS: 480D
PHASE: 3
SEC (X) VOLTS: 208Y/120
FREQ.: 60 Hz
PRI (H) AMPS :54.1
% IZ: 4.10

My question is connecting a breaker panel to this transformer ..where my neutral would come from or if I need a step down transformer to make the proper connection for a main breaker panel. If any additional information is needed let me know

Thanks
