I think I'm going to start calling it the omnibus-bar.
I understand what it means no matter how it is spelled. I kind of like omnibus-bar..


It's kind of like the folks who insist it is a cutless bearing yet the word Cutless® is a registered trademark of Duramax Marine® LLC.. The words stave, sleeve or cutlass bearing are the accepted generic terms.

Most people would have no clue what you are talking about if you used the word stave bearing but if you say cutlass everyone knows.

Re: Updating DC System

Mark, how about "spelt"? In this country, for the last 100 plus years, Spelt refers to a form of wheat...

Re: Updating DC System

I insist on continuing to use British English, despite having lived here for 14 years, on the basis that it might eventually catch on.

Spelled vs. spelt - Grammarist

Omnibus-bar fits in well with my policy of referring to the radio as the wireless, bicycle as velocipede, airplane as flying machine, and so on.

Re: Updating DC System

And here I thought a bus bar was the way to go barhopping without putting your beer down in between the bars.

Merriam-Webster....Is that like citing Barack Obama as an expert on helath insurance schemes?

Re: Updating DC System

Hi Maine Sail,

Thank you for the input. On my question #1 related to battery disconnect switches, I was assuming (I know.. I know...) that I would need to add a new disconnect (on/off) switch for each bank. The marine surveyor wrote "A single wire should lead from each battery bank to disconnect switch. That wire should be fused with slow blow fuse rated for wire gauge. All other wires should come off of buss bar aft of disconnect switch." I assumed he meant a separate disconnect switch for each bank close to the batteries before the busbars, and not the 1/2/Both/Off switch which will disconnect the batteries from the DC distribution panel but not isolate the batteries from the positive busbars and loads / chargers shown in ctj1950's wiring diagram. Am I misreading this requirement? I can add the on/off switches if needed.

Thanks too for the information about the Universal M-18 Alternator bracket. More work to do.

And to ctj1950... thanks for the diagram.. and fyi... my boat is on the hard in Mayo, MD... moving to Deale, MD in the spring. That close to you???

Thanks again.

You do not need additional ON/OFF switches on top of the 1/2/BOTH.... The only devices before the battery switch are items like the alternator, which should ideally be fused and ideally have it's own "service disconnect", perhaps a VHF, your bilge pump and any ACR or Echo type charger. On bigger boats and inverter may tie in before the batt switch, but should have its own ON/OFF and a windlass or thruster may as well..... Anything tied in before the batts switch should have sufficient over current protection.

Battery fuses should be ANL, MRBF or Class T....

Re: Updating DC System

Hey cjt1950... Thanks for the crimper usage offer. I cannot respond via private message yet... I've not made enough posts yet apparently. As FYI... my boat will be at the same location in April. So will have to look you up sometime.

Take care,

Boomer
