Clifford, Thanks! Brian, Good to know maybe I don't have a problem with the neutral-ground bond. However, during my testing - read more below, if I throw one of my main panel breakers ON, the GFI immediately blows. If I leave all of them Off, it works for 5 - 10 minutes and then blows.

I have disconnected the green ground wire in the Trace and left it disconnected. The shore cord is a 50' 30amp 10 ga. It is not curled up - I always stretch it out and then bring it up to the bus. However, I have a 15/30 adapter at one end and a 30/50 adapter at the other. This 15 a circuit is in an outbuilding that is quite a long distance from the house panel and it has a household refrigerator on it that I cannot disconnect. In consideration of that possibility, I set my inverter to Charge only (no invert) and the charge amps to 5A. During my testing, I had all breakers in the bus Off so that only the inverter/charger was pulling a load. I have a power conditioner that indicates 117 volts AC, 5A AC and 60 hz after throwing the breaker in the bus. Those values hold steady until the gfi blows.

Most boats are still painted with brush. Course it is usually with two painting side by side to achieve two coats immediately and be able to brush any sags or drips. Marine paint is probably the best (translated expensive) paint made. Good Luck, TomC

What gauge is the wire fed by that breaker?

I've powdercoated several sets of automobile wheels, but never a bus/truck wheel. 

I've never once had a problem with flaking, peeling, or cracking.  Prep is everything.  That stuff finishes up as hard as paint, maybe harder -- I even used PC on an entire car tube chassis one time.  Anyway...I pull my wheels on and off for rotations, balances, and tire replacements without a worry.  I usually pay my local shop about $75/wheel, including strip and prep of whatever was on there before.  (That's for much smaller wheels, obviously!)

Cheers, John

You just have to change the front studs only they sell longer nuts for the duals on the rear fwiw oops I see you have hub piloted wheels you would need to change the rear also

Our GFI is in the breaker box inside the house not on the plug ours would always pop if she had something plugged in on one of the GFI outlets which she always did I finally tossed the 15 amp and installed a 20 amp GFI breaker in the box very seldom does it ever pop now Roll Eyes should have went with 30 amp

I went by my tire place today and they told me powder coating the wheels was a 10 day turn around and they charge $25 per wheel. I like the idea of the Alcoas but want I have to change my lug nuts? I was thinking the aluminum wheels were thicker.

I have an ESCO 350 ATS that handles the switching of generator/shore/inverter, but a conversation with ESCO TS reveals that switch does NOT do any kind of neutral/ground bonding or "lifting". I know that my generator ground and neutral are bonded to the chassis at the generator, but I am not able to discern how the neutral-ground bond is being lifted (if it in fact is). I have never had any problems with my electrical system either on gen/shore or inverter.
I welcome any suggestions as to how to proceed.

The Esco ATS has relays that switch the two live leads and the one neutral lead (it's a 50 amp 120/240 volt three source ATS) so that whatever power source is providing power is switched through to the load.  Since it switches all three leads, any ground-neutral bonding that is present at the power source in use is also switched through.  That means the ground-neutral bond at the generator is "lifted" - actually just disconnected from the bus power system - when the ATS is not using the generator for power.  


Did you remove the jumper that connects that filter cap that Sean referred you to?  Is the GCFI now tripping after 3 - 5 minutes with the ground connected or disconnected to the bus?  I can't think of anything that would slowly and consistently develop a current leak in the 5 - 10 milliamp range over a period of minutes.  I just had a thought - how long is your power cord to the bus, what gauge is it, and is it coiled at all or laid out straight?  A coiled cord will inductively couple from live or neutral to ground.  Even a longish uncoiled cord can inductively couple.  

Edit:  I want to go on record that I thought of the long coiled cord thing BEFORE I googled it and found that it's a known cause of nuisance trips.  I also want to know if you've checked the obvious stuff like other outlets with stuff on them downstream of that outlet, and if it's an outside outlet possible corrosion or moisture?

I swapped out my 4speed for an MT654 auto 2 years ago on my MC7 w/8V71. Best thing I have done for the coach.
I think the extra parts and some custom machine work ( including the driveshaft shortening ) was about $2K extra.
I replaced my engine doors with one large mesh door that has a Hayden cooler mounted on it to cool the auto.
Works very well. Also installed a pair of 15" electric engine fans on the cooler (just in case) and that was a waste of $$. Never used them.
I replaced all hoses, replaced starter and alternator at same time. Steam cleaner spent half a day cleaning the engine/trans and engine compartment (well worth the $$). Also spent a few hours welding and reinforcing cracks in the steel framework in the engine compartment.
I think in all spent about $6K.
2 return trips from Canada to Yuma, AZ towing a 4600lb toad, including over the mountains in Wyoming, and never saw transmission temps about 220.
I would do it again definitely.....or I would buy an automatic coach to begin with.

If you had a ground it would trip the GFI instantly that is the purpose taking minutes sounds like a overload but I not that up on inverters and grounds either
