To comply, use pin terminals on 22-10 ga wires with setscrews. I like the eurostyle nylon blocks for end connections on devices like lights, etc. for easy service, but that's all. Ring terminals under screws are definitely preferred. For re-work, use locking or flanged fork terminals to avoid losing screws.

Rick-
Picture your white plastic things (agreed as to their value) and now imagine they had been fabbed up from a large aluminum BLOCK instead of cheap plastic castings. Big block. With two 4-g holes in one end, and a dozen 10-g holes in the other end, each hole of course having the matching screw to cross down and secure a wire.

Those black plastic ones are called "barrier strips" and the only real use I had for that, was connecting masthead wires where they jumped from the mast to the bulkhead, where we needed a good way to disconnect them from the hull's wiring.

Thanks, Gord, I didn't have time to get images. That's the right way. Picture solid conductor 'Romex' wire on a boat, that's what setscrew lugs are made for, and they're also suitable for heavy strand THN wire used in equipment, but not for 30-strand marine wire. I like to picture quality terminals, properly crimped. Why search for alternatives to what works? Extra time and patience at the start is the cheapest and fastest thing you'll ever have on your boat...

PIN terminal crimps? Gord, that's fantastic! Something else my local hardware store and chandlery have never heard of.<G>

Nate-
"Ring terminals under screws are definitely preferred." I fully understand and appreciate the concept, but I have a very real love-hate relationship with anything that may force me to undo a screw--which then vanishes into the bilge. Worse, vanishes under my twisted legs, the spare anchor rode, fenders, and lazarette-bottom-dwellers, into the space under the engine.

But if I ever have to do an installation to ABYC/USCG specifications, I'll think about using the confounded parts they require in the places they require them. Maybe. <g>

For “SOME TYPICAL TYPES OF TERMINALS”, goto Figure 17, on page 46 of ABYC Section E-11 at: https://www.abyc.com/committees/.%5CE-11.pdf

No, no, not aluminum! Never, ever use aluminum for electrical connections or wiring! Tinned copper is what you want for both wires and bus bars.

Yes, aluminum bad. Didn't want to pay a machinist to make a bronze one, couldn't find anything else on the market. So...Neverseize and Boeshield it is.
