Question:
On a residential service what is the maximum distance the service conductors can travel with in the structure without over current protection.
Rich Kortkamp
A
Answer:
Hey Rich thanks for your question. The service disconnecting means, if inside a building or structure, must be located nearest the point of entrance of the service conductors as stated in 230.70(A)(1). No specific dimension is given but as you mention those conductors usually do not have overcurrent protection on the secondary of the utilities transformer. Check with the AHJ to see if there are any local requirements for a specific dimension.
