Hey Maine Sail, I want to add a Blue Seas terminal block fuse to my house bank. I'm pretty competent with most every system on our boat except the electrical. The photo shows the battery cable used on our boat. I'm hoping you can verify my numbers for the size fuse I should use. According to the chart you posted in your Battery Fuse Sizing tutorial, my 100% ampacity rating would be 147.6 for an inside engine space so I'm assuming a 150A fuse would be ok. !50% ampacity would be 221.4 so a 200A. Another question I have is under what circumstance would I need to go up to 150%?
Thanks for all your help!
