Protection on AC Shoreside Cable Connection

Question:

Hi Jeff. Hope you doing well.  What is the reason ABYC calls for a circuit breaker if the conductors are over 10' from the shore power inlet to the main AC panel? I can't find the "why" anywhere.  Thanks!  - Brad

Answer:

Hi Brad, it’s all about circuit protection. Ideally, you’d want an even shorter amount of unprotected AC cabling inside the boat. The longer and unprotected the cable run the more likelihood of a fire in the event of a short.  - Jeff
