Super fast hair drier and vacuum cleaner

[ESCAPE PLAN]

Good afternoon all, i have an issue with some of my 110v outlets.My wife smoked 2 hair driers and a vacuum cleaner on 3 different outlets i hookedUp a meter with a plug in outlet tester and it showed 30 rev hot ground.I tested each wire seperately black had 112 and white had 112. Neutral should have zero volts right?Or am i missing something?

 

[Captain Ralph]

Just to make sure, you measured 112Vac between black and white?

Black to white and green should offer 112 to 115Vac.
White to green should be zero.

Some times you may read noise between green and white.
I use a test lamp as a load between wires to ensure I'm reading 115Vac, Noise should go-away and then be truly zero.

Pending if you do not have a service transformer, white and green are tied at the dockside power pole.
When you are off the dock, Your gen-set and/or inverter ties white and green.

If you do have a transformer, White is generated in the transformer. Green may go to shore or the ships bonding. Pending who/how it was wired when assembled.
Here is where white & green may offer that noise.

Now, another leaking appliance passing 115Vac to the white or green wires call for extra Excedrin for that soon to be had; headache.

what do you mean by “ showed 30 rev hot”??

You should have around 110-120v between both terminals as well as between H and G. N to G should be zero

What are you getting between H and N ?

 

[ESCAPE PLAN]

Voltage between black and white is 250vVoltage between white and green 125v should be 0 yes?Voltage between black and green 125vI beleive the transformers have been removedIt was also wired for european along with the fact. wiring.

30 rev gnd hot is what my meter said. It has a plug tester option on it

 

[MadHatter53]

You have 250V ac at the outlet ? Is this issue new ? Hook your meter back up and have someone start turning off breakers and see if voltage drops.

 

[ESCAPE PLAN]

This vessel is new to me im finding out all sorts of crap. I think i might err on the side of caution
And hire a electrician, it is my home and i dont feel like losing it. Any recommendations in the Ft. Pierce area ?

If you have 250v between black and white, these outlets are wired for 240v! You have a serious problem there. Turn off the breaker for these outlets right away

 

[Captain Ralph]

It was also wired for european along with the fact.

Oh Sheet.
Most european stuff runs on 200-220Vac. Your purchase surveyor did not pick up on this?

Yes, To save any more equipment and more (great safety issue), Get a real marine electrician on board.

 

[ESCAPE PLAN]

That is the plan. Some things i will do but i dont screw around with safety.

 

[madhatter1]

Another possibility is lost neutral. Bad JuJu. When neutral is lost voltage floats out of control on the 2 legs based on load.

 

[ESCAPE PLAN]

Ok, i may have found something, i went down to my 120v service c box and found a black #8 wire attached to the neutral bus, the is also a #8blk/red attached to the line on the breakers.
According to my diagrams the black should be the line in on the breakers and blk/red for the spare breakers which i do not have.

Brother, Do you Really know what you are doing?
Guessing?
Asking non-electricians on a web site?

I type this not to be a smart asp or bum on you, but to apply a heavy load of caution your way.
Not just another vacuum cleaner can be at risk while diving into heavy amp services.
Please be extra careful.

Im just reporting what i found,and looking at my Hatteras supplied wiring diagrams it appears to be wired incorrectly. Im not a certified sparky but im no idiot either. And it does seem as if there are a few people here. Who have more knowledge than myself.

Question asked, question answered. Your generators probably run at 50 Hz also. It may be a straightforward remedy, but you really need someone who knows what they're looking at to throw eyeballs on it in person

 

[ESCAPE PLAN]

Gen runs 60hz and marine electrician coming tomorrow.

 

[Avenger]

Sounds good. I just think you're asking a lot of a forum when you're dealing with something that's non-standard and we're not able to see the whole thing while relying on partial descriptions. Hopefully your electrician can get the whole picture and get your electrical back to original.

With the previous mods for europe, there is no telling what is wired to what.
You may have well been rite on to something but Murphy is not a sparky either, but he lurks in the wires.
On our Aqua Space Ships, We need to be extra careful on some systems.

Glad you have a real marine electrical tech coming.

 

[jim rosenthal]

What Ralph said- good that you have a professional coming to look at it.

The chance of Hatteras wiring the boat wrong versus someone screwing it up later in its life... I would bet that someone screwed it up later on. Hatteras Yachts was one of the very few boatbuilders who had their own electrical division with engineers designing the electrical systems and electricians wiring the boats.

 

[ESCAPE PLAN]

Well,
1st electrician spent 2-3 hrs on it and decided that this will take more time than he had yesterday(he had another job and squeezed us in) he's going to Belize tomorrow for a 2-3wk. stay.
he suggested we look for someone else as we need this figured out right away.
i found out that the installers of the euro wiring was Wards Marine Electric in Ft. Lauderdale, so thats who we are talking with today. if they have to, they will come to Ft. Pierce to look at it and come up with a solution.
