I go Blue Seas for everything. It is very good gear and usually is all over Ebay. For bonding/grounding, you want a nice big bus bar for ship's ground and run EVERY ground to that one spot. Bonding thru-hulls is a complicated subject. Mine are not bonded and I like it that way. Others do the opposite. For shore power, an isolation transformer is the best, but somewhat big and heavy. I use a galvanic isolator. The green wire AC ground does connect to the ship's ground and the incoming green wire from shore goes through the galvanic isolator. This keeps cheap bastards in the other slips from using your zincs. I use various ferrites on leads related to the SSB for RFI suppression. They are pretty cheap off Amazon or Fleabay.

I have been reading about bonding, grounding, panels, etc. and my head is spinning, so thought I 'd turn to the list for some collective wisdom Here's a few: What sort of panels do people recommend? The spread is for a couple hundred bucks for a fuse panel to well over a grand for a combined AC/DC Blue Seas baby. I am removing the old combined AC/DC panel above the companionway with one 6 gang panel in the cockpit and a 12 position plus 3 AC at the Nav Station. SHORE POWER Ok, so who is using an isolation transformer? Do you connect the DC Negative at the battery with the AC ground on your incoming? BONDING/LIGHTNING PROTECTION Who connects all the rig, prop shaft and keel in one electrical bundle also connected with battery ground? Has anyone ever considered bonding the aluminum toe rails? RFI shielding What do you guys do to reduce RFI cross talk? That's it for now. This will be a simple boat, VHF, GPS Simrad WP30 Wheelpilot and Standard Instruments. The power supply for the electric motor was done already by a marine electrical guy and works extremely well. Suggestions? Let 'er roll!
