SIMPLE AC Distribution Panel?

You'd be best to do some research on the subject, so you actually know something about the ABYC, and how it works, before making such blatantly incorrect and demeaning comments.
I've been researching and studying various ABYC rules and regulations for over 20 years while I fight about them with surveyors and insurance companies (as I said: the surveyors blindly follow ABYC and if you're not compliant, you can't get insurance.)
One of my friends is one of the top gasfitters in Vancouver, and he had a LOT to say (mostly bad) about the way ABYC required him to plumb the propane on my boat. Why is the required pressure gauge on the wrong side of the solenoid for a leak-down test? Why is there no VISIBLE way of ensuring the solenoid is closed (which is a requirement for WCC lockout procedure)? And so on...
And if there is SO much preparation for every regulation, how do you explain the miriad of changes to wiring colour-codes for AC and DC wiring over the last 10 years?

Sorry, I stand by my rant. The constant changes you make require us boaters to put out thousands of dollars for "upgrades" that may well be completely unnecessary.

I should apologize - my Rant was borne from years of frustration based on changing ABYC regulations. I did not mean to insult anyone.
However, if anything (somewhat) positive can be taken away from this, it is this: Main Sail, next time you're in one of those committee meetings, working out wording, etc., please understand that although ABYC is INTENDED to be mainly a guide for new boat construction, the Surveyors and Insurance companies here in Canada take it as Safety Gospel. What this means is that your recommendation for ELCI makes my perfectly-safe 40 year old boat suddenly non-compliant. And, depending on how the Surveyor words it in the Report, it can mean the boat is not insurable. And THAT means I can't get moorage for it, or even haul it out. Essentially the boat is worthless.

Please take this into consideration when you're making these changes.

Why is the required pressure gauge on the wrong side of the solenoid for a leak-down test?
"1.5.2
Each system shall be fitted with a pressure gauge. The gauge shall read the cylinder pressure side of the
pressure regulator."



There is no requirement for the solenoid to be after the regulator but there is a requirement that the pressure gauge be before the regulator because regulators are prone to corrosion & failure, I have seen three failed regulators over the years.. Even if you did place a "low pressure" solenoid after the regulator a leak down is still simple and is now inclusive of the regulator, which is part of the intent, because regulator can fail. The solenoid can be either a high or low pressure model and it can be placed one either side of the regulator.

"1.7.3
A readily accessible manual or electrically operated (e.g., solenoid) shut-off valve shall be installed in the
low or high-pressure line at the fuel supply."

This just means the solenoid can be before or after the regulator but you will need to choose either a high pressure model or a low pressure model. A high pressure solenoid can be used on either side but a low pressure solenoid can only be use on the low pressure side of the regulator.

Why is there no VISIBLE way of ensuring the solenoid is closed (which is a requirement for WCC lockout procedure)? Well there is a switch. These devices are designed to be fail safe meaning they power open and have a strong spring for closure. If you know of one that has a visible indicator, that is also IP rated and 12V, 24V etc. let me know..
If you place the pressure gauge after the solenoid, in other words tank valve>solenoid>pressure gauge>regulator>system hose, you simply close the tank valve with the stove running to reduce line pressure. Once flame get really dim turn off the stove burner. Now close the solenoid and read the line pressure. Now open the tank valve quickly and close it. The solenoid should maintain this pressure for the leak down testing of the solenoid.. Again, as above, there is no requirement for the solenoid to be on the low pressure side of the regulator. It is only the pressure gauge so it can be inclusive of the regulator.

FWIW ABYC A-1 is also Federal Law under the US Code of Federal Regulations so it is not just the ABYC who has examined this safety standard.


And if there is SO much preparation for every regulation, how do you explain the miriad of changes to wiring colour-codes for AC and DC wiring over the last 10 years?
The only real change I know of is adding yellow as an alternative color for DC negative. This did not make black for DC negative obsolete at all. Any surveyor who can't comprehend this should be hung up by their boot string..

Sorry, I stand by my rant. The constant changes you make require us boaters to put out thousands of dollars for "upgrades" that may well be completely unnecessary.

Your rant is misdirected. ABYC standards are not law in Canada, yet, though some parts of it are for inspected vessels. The rumor circulating is that Canada may be making more of ABYC mandatory (even for recreational boats) if the rumors are true. If this is true then you need to take this up with your own government or moving forward it will only get worse.

Your issue is with your surveyor and NAMS & SAMS & their often incorrect interpretations of the ABYC standards. I can't even begin to count the number of times a surveyor has misinterpreted the language/intent of the ABYC standards. Your rant/issues also lie with your insurance company who blindly accept a report from an often under-educated surveyor who many times simply make up rules as the move along. I just went this this in June regarding batteries. The surveyors gross misunderstanding of the standard was going to cost the owner many hundred's of dollars until he called me. One fax to the insurer explaining the actual standards, as related to the owners actual installation, they dropped it. Surveyor was simply under-educated and misinterpreted the standard. Heck you yourself misunderstood A-1 as related to the requirement for solenoids placement.

I even had one insurer mandate the external lead keel be bonded to the mast for lightning bonding. This despite TE-4 NOT being a required standard. The insurer claims that they have less hull damage on boats with a lightning ground. In this case your issue would be directly with the insurer as TE-4 is not even a standard.

ABYC standards are voluntary at this point for recreational boaters, unless you have an inspected vessel, at which point a lot of the ABYC standards are Federal Law...

BTW if you want an inexpensive AC/DC panel the Blue Sea 8029 is a good deal. It has 1 branch circuit and 1 30A double pole main breaker. It also includes the reverse polarity circuit. The last one I sold to a customer was last year and I billed him $102.00 for it..... There are many thousands of boats in Canada that don't have ELCI main breakers and I am assuming most of these also have insurance. I worked on a transient boat just earlier in Aug that did not have an ELCI.

MS,

I appreciate your commitment to safe boating and helping the masses. Could you help us understand the reasoning behind the ELCI requirement I, for one, would appreciate it. If adding an ELCI to my AC system at a cost of ~$150 will make my boat safer for me and others then is it is a small cost to bear.

Thanks,

Dave
An ELCI would not allow this level of leakage current to exist. A balanced power cord, same current on HOT & NEUTRAL reads 0.00A... In a recent marina survey I found that 14% of the boats, that were actively drawing current while plugged in, were well exceeding 30mA of leakage, with many of them looking more like this. I have measured boats losing 6A +... Imagine if the 60 other boats that were plugged in, but not drawing current, were actually trying to pull 15A+.... This is simply scary! My findings are sadly not that far off of what has been "normal" at marinas for a long time.

Druid - there is a AC panel in the classifieds here for $70 -- a few more breakers than you wanted but price is good.
