I was recently doing an outdoor panel replacement that was ripped out accidently by a landscape crew during excavation. The panel was a 100amp sub panel fed from the residence and intern fed an open u shaped dock. The dock was a private marina where the home owner rented out 5 slip spaces. Each slip had a120v 20amp Duplex Recepticle and a 120v 30amp Twist Lock Recepticle. The 20 amp recepticle were protected by GFCI Breakers and the 30 amp recepticle were only protected by single pole breakers. The original install was 20 years ago and the 30 amp recepticles were not at least 12 inches from the decking and installed on wood posts over the open water. Not to mention the oulet boxes were weather/sun beaten and damaged.
During instal I insisted that the 30 amp shore power recepticles be GFCI protected for several reasons. First is that I felt that the new 2011 code read that all dock,marina and boat house recepticle be GFCI protected. Second the boxes being worn and damaged. Third that the recepticles were over open water not 12 inches above the decking. Forth the PVC Consuit was damaged and the UF that was fed through was showing and subject to multiple wear factors.
My Questions are.
1. Was this an appropriate decisssion given the circumstances listed. And that the home owner was not willing to make any other repairs.
2. Why is it that 120v 30 amp Shore Power is not subject to the same GFCI protection requirements as 120v 20amp recepticle especially with the currently availible technology and the current GFCI and Arc Fault Craze that the NEC is in today.
Thank You,
