mitiempo I think I prefer Blue Seas panels.

All double pole though, breaking hot and neutral. More like what you should see on a metal boat.

Bene505 Here are some pictures of the breaker panel. First the front of the panel.


And a zoom-in of the front of the panel.


Then the back of the panel. There is a bus bar that I think I can remove and use wires instead. It is the thing that has the number 004938 on it.


Each breaker handles two wires (hot and neutral, IIRC). There is a common ground strip (at right). The circuit breaker for the outlets is wired to 2 strips (hot and neutral) for all the outlets to tie into (at left).


Here's a zoom-in of the main breaker.


Looks like all the AC outlets have ground-fault-detectors, except for the new ones the PO added. I'll have to look into that.

Regards,
Brad

Bene505 On the panel there's a green light when shore power is supplied. I could put another one of those in the panel to show that there's inverter power being supplied. There's just enough room for it. I'll have to think again about the other approaches, when I make some time for that.

Regards,
Brad

That's why I like the main panel to inverter to sub panel plan. It makes it real obvious what the inverter is able to power.

Gee, that's one of the reasons I really like wiring option 1, because everything comes thru the main AC breaker on the boat. When it's off, "you don't need no stinkin' signs" saying you can be electrocuted even if the main power switch is off.

Just my simple approach... KISS, consider it, Brad. Bypassing the inverter makes less sense since you mentioned this, I'd forgotten the unforeseen and unintended consequences.

All the best, glad we could, and will continue, to help.

Remember the neutral feed to the inverter must be separate from the neutral output as well as the hot in/out being separate. Most panels have a common neutral bus. They usually also have a common hot bus that the feed side of the breaker connects to but yours apparently does not.
The inverter needs these separate otherwise it will backfeed - AC feeding into the output of the inverter.
Grounds can go to a common bus.

Bene505 Update:

Stu sent me the 1998 manual and it looks like a match. Thank you Stu! (Someone else add to his reputation, since I can only do it once and already did for something else. Click here.)

I went to the boat today and took the circuit breaker cover off. Sure enough, each breaker is wired independently. There is a busbar that fits where wires can also go instead. There should be no problem using the single circuit breaker box and have part of it hold the "sub-panel" for the inverter/charger and it's 110v outlets. I'm really glad about that, since it's so much easier that way, and I won't have to find a place to put a sub-panel box.

I plan to label the breakers as hot even when the main breaker is thrown, with a note to "check to make sure the inverter is off".

I have room for one more breaker in the box, so I'm planning to put in 2 breakers for the outlets -- maybe 1 for port-side outlets and 1 for starboard-side outlets. The previous owner put extra outlets in. [Calling Mark Brazier -- if you are out there please contact me, been looking for you. Free beer for you ]

I even found some breakers on eBay that are like mine.



I'll try to post pictures during lunch tomorrow.

(Also went to the top of the mast to install a block for a lightweight halyard and to "install" anti-seagull/anti-cormorant monofilament. That will be another thread when I get a chance.)

Regards,
Brad

Stu Jackson Sent. Armed with that info, save the phone call. They usually don't respond well to information about equipment they claim they don't know anything about. Heart made those units and X bought them out.

Yes, I got it off the web.

Stu -- I'll pm you my email address. And will call Xantrex during the workweek.

Why not get in touch with Xantrex and ask them. From my ramblings through their website that isn't easy, so you'd need a telephone.

I could provide you with PDFs of our equipment manual, circa 1998. Send me a pm with your email and it'll be on its way to you. I only have the installation manual, not the second book with the dozens of other wiring schemes. But I also have the 2002 manual that does. Be willin' to send ya both.
