I am doing work at a marina, specifically we are raising up an existing 200 amp single phase 240v electrical panel on the shore that gets flooded when TVA raises the water level on the TN River in the spring. We met with the AHJ to put together a plan and the big snag that came up was he said the floating office/store/gas station that is fed with a 2 pole 100 amp breaker must be GFCI protected. It currently is not because it was built in 1993 but since we are messing with it now the protection is required.
Apparently they don't make a 2 pole 100 amp 240v GFCI breaker. I asked AHJ what to do and he said he didn't know, this was a first for him as well.
I did some research on this forum before posting and only saw the big money LifeGuard Series GFCI's as a solution. Is there a cheaper way? Is there a GFCI monitoring setup that could trip a 100 amp shunt trip breaker? I'm just spitballing here lol. My last ditch idea is to do a load calculation and see if its possible to just use a 2 pole 60 amp.
Thanks in advance!
