All good avice!

You've received good advice thus far. Here are a few more things to consider.

A great wire gauge calculator: Wire Gauge Calc (LINK)

Marine Wire Termination/Crimping (LINK)

Use tinned marine wire! There are MORE than one manufacturer. I use Berkshire wire but Cobra and Ancor also make good tinned wire.

Use heat shrink crimp connectors. They are more expensive up front but well worth it. The best prices I have seen on small quantities can be found at Sailors Solutions. I worked with Nick to get him using & selling this very high quality crimp for MUCH less than Ancor!!:

Sailors Solutions Crimp Terminals (LINK)

Sailors Solutions also has the BEST price on the proper tool for crimping heat shring connectors!!

Single Ratchet Heat Shrink Crimper $39.95 (LINK)

I have NO vested interest in Sailors Solutions and am a CUSTOMER, who pays full price, just like you guys. I only worked with Nick because no other company / vendor was willing to listen and they all want to sell the "GRAB YOUR ANKLES" stuff made by Ancor which is very pricey & inconsistent especially with their crimp connector sources!!!

I have a distributor up here who sells the same crimps as Sailors Solutions but the smallest quantity is bags of 100..

It depends what you want to do. The panel I got was from Hamilton Marine, built in circuit breakers and 6 switches. My electric needs are minor, no windlass or fridge or anything like that. Just lighting and other small gear so did not need a big one. I have no AC either. You can spend a lot more if you like. I agree on getting a new panel though. Kind of silly to spend hundreds on new wire and spend all that time to salvage a 30 year old panel.

sailingdog If the appliances are in good shape, no real need to replace them IMHO. I'd highly recommend getting new circuit breakers and panels though, since the old ones may or may not be marinized and may or may not be about to fail. It'd be a shame to have a new wiring project burned up by an old panel.

KasbeKZ thanks a lot for all the advise. i guess i am planning on re-doing the wiring then. will i need to replace a lot of appliances? or just the wires going to them?

i'm pretty good with labeling and all. i've done a top end rebuild on my 1990 300zx and got PLENTY of practice lol.

sailingdog BTW, do try and avoid using BLACK for AC hot and DC ground...use YELLOW for the DC Ground... makes your life a lot easier and may save it.

SailorByFate From my own experience rewiring a boat:

Do the AC wiring first because:

(1) You generally want to keep the AC wires away from the DC wires to avoid introducing 60 Hertz hum in DC devices. That means you can often replace AC wiring without disturbing the DC wiring.

(2) When the AC is done, you'll have convenient power that you'll need for the DC rewire: namely good lighting and a heat gun.

(3) Bad AC wiring can be far more dangerous that bad DC wiring. A corroded wire nut can easily create a fire. (Wire nuts should never be used on a boat.) And AC voltages can easily kill a person.

(4) AC wiring is generally simpler than DC wiring. There's less of it and the wires are smaller and more manageable. You'll have an opportunity to test your abilities before the much larger DC rewire project.

All that having been said, be sure to think through your AC needs before you get started. And read up on marine wiring standards. Marine AC is very different from home AC.

rayncyn51 My new-to-me 79 Catalina 30 is getting a complete re-wire. Original wiring diagrams are available from Catalina, then add your updates from there.
