Re: Lightning prevention system.

Within a foot or so. The other aluminum box is a homemade surge protector for the mast lights. The hull mounted copper ground plate is sitting right below that location.

Re: Arcing in 30 amp shore power cord? (Picture)

This is not going to help your problem but might others that read this thread. A few weeks back I was working on my boat (mostly cleaning interior surfaces). I was running the 12,000 BTU AC to keep...

Re: How much weight can go on the mast ?

in bygone days the crew would often hoist a cannon to the top of the mast to reduce rolling at anchor (probably before aluminum masts).

Might consider what could be located around the radar just...

Re: Electrical Panel replacement

Re: Island Packet 29 - would you take it far Offshore?

Re: Raytheon question

Re: Wiring size thread

Fuse it at 2 amps and find something else to worry about. Next standard size above 125% of full load current is a pretty common applied ROT.

I think you are below the ABYC radar looking for your answer. 1 or 2 amp ATO/ ATC fuse and #16 duplex would be my suggestion. If the coils are in close proximity just install a terminal strip with...
