Work-around - velcro!
Thanks Mark:I have thought about calling them but in the end, I think I will put some heavy duty velcro on the CB I have sourced and attach it to the inside of the panel. This way, if the CB trips, I can reset it (I will have to remove the eight screws holding the panel face).I think it was exposure to weather that caused the initial CB to fail. I replaced it temporarily with a normal fuse holder and equivalent fuse. It has only tripped twice in several years. I think it was after letting the exhaust fan run for a long time and starting at the same time.I installed a tankwatch 4 on my tank today. I will try and post pictures over the next few days.I won't be in the water until May. I head back to West Africa to work for 28 days next week.RegardsChris
