Question: I wonder if you could tell me the following - I need to know the meter tail size for single insulated tails contained within metal trunking, for an 80kVA three-phase and neutral incoming supply?
Answer: From your information, you will have a load current of just under 110A/phase and, therefore, 35mm tails should suffice. You would need to increase to 50mmm tails if your design current is between 110 and 134A/phase.
