I am member of 50 households which bought a 11kV 420 100kVA Transformer in an informal settlement. I am not knowledgeable on this subject. We want to avoid misinformation. Question: Electrical suppliers want to know the size of the overhead cable to run from pole to pole, which 20m apart. Each pole will supply 4 houses. Each household should limit its electricity requirement to 1x32A (Stove), 1x20A and 1x10A circuit breakers. Suggestions include 35mm (2core +1E [naked wire]) or 70mm (3Core + 1E) cables. What is the correct cable size required? Will the cable not overheat and burn the transformer at maximum use? Please help.
