11kV/400V TX with no LV protection

amlec2021

I am working on a project where we have been asked to install a new LV cable from the outgoing side of a transformer to a new Panel board however the outgoing side of the transformer does not have any protection. We have raised this with the client however they have advised this is not an issue. I am looking for some guidance to back up our argument that the LV cable does not have any protection.

  • It is somewhere in the regulations, words to the effect of "conductors that connect generators, batteries, or transformers with control panels do not require overcurrent protection"
