Hello everyone,
following situation: The supplier is laying a NAYY-J 4x50 cable, approx. 10 meters, on our property into a transfer cabinet. From here, we have to organize the rest of the development to the house ourselves. It is another 70-80 meters to the house. (House is being built in the third stage) The power requirement is 30kVA. Now we have received different statements and different offers from electricians. We were definitely recommended to use a copper cable.
Electrician 1 recommends at least an NYCWY 4x50 SM35 cable. Due to the length of 70-80 meters, he actually recommends taking 4x70, as otherwise there may be a voltage drop at this length and the 30kVA can no longer be guaranteed.
Electrician 2 recommends NYCWY 4x35 SM16. This would be completely sufficient.
Is E1 or E2 correct? What would you recommend I take?
Thank you in advance Müller
