ECN Forum Forums General Topics of the Trade General Discussion Area Isolation Transformers

Good Day,
I have a question regarding an Isolation Transformer where I work
It is a GE type QL-TE
Model # 9T23C3035
75 kva
3 phase 208 Volt
The windings have a lead (14AWG)coming out of each one, Does anyone know what these leads are for? Any help would be appreciated

Thanks,
