The wiring on my 35 MK I was horrible. It was all untinned 16 gauge stuff the crumbled into black dust after 3 Bermuda trips. I have very little of it left.

Some of the wires disappear between the headliner and cabin top, which makes them nearly impossible to replace, and maybe subject to chafing, or damage if you drill any new holes for fittings (like for a dodger in my case). The wiring is only 16ga, which is borderline for the long runs, so don't put larger fuses than the load demands in to avoid melting wires. I'd love to see some photos of what the original looks like, as mine is very far from it... I'll share some once I am done the re-wire... -- Shawn Wright shawngwri...@gmail.com<mailto:shawngwri...@gmail.com> S/V Callisto, 1974 C&C 35 https://www.facebook.com/SVCallisto<https://protect2.fireeye.com/v1/url?k=e491866f-b807d7ca-e491af18-0cc47adc5e34-769ec93efe0876a4&q=1&e=522017d4-a893-4399-9f1e-43f43f789495&u=https%3A%2F%2Fwww.facebook.com%2FSVCallisto> On Wed, Apr 22, 2020 at 3:28 PM dwight veinot via CnC-List <cnc-list@cnc-list.com<mailto:cnc-list@cnc-list.com>> wrote: Is there a big problem with the wiring and circuit panel on my 1974 35mkii. I have original stuff mostly with glass amp rated fuses for circuits on the panel. All systems work fine.

The newer BlueSea 4322 panels that I am using have these, and they are made by Carling, like most of the BlueSea breakers. They come only in 15A rating, but Carling does make other values as well, so one could swap them out. For the few circuits where the wire size does not support 15A (like the long masthead and bow light runs, where 15A would necessitate 12ga wire), I am will be wiring through a small ATO fuse block after the breakers to protect the wire. This is the panel, and the individual breakers look like standard rocker switches. https://www.bluesea.com/products/4322/Water-Resistant_Circuit_Breaker_Switch_Panel_-_Gray_6_Positions<https://protect2.fireeye.com/v1/url?k=20003ccb-7c966d6e-200015bc-0cc47adc5e34-68ba0daa0f3ad34e&q=1&e=522017d4-a893-4399-9f1e-43f43f789495&u=https%3A%2F%2Fwww.bluesea.com%2Fproducts%2F4322%2FWater-Resistant_Circuit_Breaker_Switch_Panel_-_Gray_6_Positions> This is the actual breaker used: https://www.mouser.ca/datasheet/2/65/C1005B_from_Thermal_Catalog-1776146.pdf<https://protect2.fireeye.com/v1/url?k=ea247c53-b6b22df6-ea245524-0cc47adc5e34-db8f400f72f197a4&q=1&e=522017d4-a893-4399-9f1e-43f43f789495&u=https%3A%2F%2Fwww.mouser.ca%2Fdatasheet%2F2%2F65%2FC1005B_from_Thermal_Catalog-1776146.pdf> -- Shawn Wright shawngwri...@gmail.com<mailto:shawngwri...@gmail.com> S/V Callisto, 1974 C&C 35 https://www.facebook.com/SVCallisto<https://protect2.fireeye.com/v1/url?k=2e4730d8-72d1617d-2e4719af-0cc47adc5e34-b5006dceab62c1b5&q=1&e=522017d4-a893-4399-9f1e-43f43f789495&u=https%3A%2F%2Fwww.facebook.com%2FSVCallisto> On Wed, Apr 22, 2020 at 9:27 AM Josh Muckley via CnC-List <cnc-list@cnc-list.com<mailto:cnc-list@cnc-list.com>> wrote: Depends. If they look like little "coffee pot" switches then they are just switches. If they look more like a breaker and are mount with the operator through a hole in the panel with 2 screws o either side then it is a breaker. If it is a breaker then loosening the screws and removing the unit will reveal an amperage marking. If it is a switch then the breaker is elsewhere. My 37+ has a switch panel that makes a very clean and compact power distribution panel. Behind the panel is a row of breakers and terminal boards that provide the over current protection. I'll share pics off list.

For some reason, I got it in my head that the switches on my panel were circuit breakers. I don’t think I have ever had one pop, and I realized the other day that none of them are labelled with an amperage. So now I am wondering if they are just on/off switches. I have looked online and see that you can buy similar panel switches that incorporate a circuit breaker and those are labelled with the amperage. So are these breakers or switches? If switches, how are the original panel circuits fused or maybe the question should be, how are they supposed to be fused?
