What is the ABYC Standards?
ABYC Standards are the basis of certification programs, marine surveys, and legal judgements. In product liability lawsuits, ABYC Standards are the authoritative reference for evaluating issues of design, construction, maintenance, and product performance.
Are ABYC standards required?
Portable gasoline fuel systems are covered by ABYC H-25, Portable Gasoline Fuel Systems. The United States Coast Guard has promulgated mandatory requirements for gasoline fuel systems in 33 CFR, Subpart J, Sections 183.501 – 183.590. Refer to the CFR for complete, current federal requirements.
What is NMMA certified?
NMMA Certification is a program designed to help boat manufacturers comply with industry safety and construction standards and federal regulations. In order to be NMMA Certified, boat manufacturers must certify each boat model they produce.
What does a galvanic isolator do on a boat?
The function of the Galvanic Isolator is to provide AC continuity of the grounding conductor (required for safety in the event of an AC fault) and to block the flow of corrosion-causing galvanic current.
What size of boat is considered a yacht?
To be termed a yacht, as opposed to a boat, such a pleasure vessel is likely to be at least 33 feet (10 m) in length and may have been judged to have good aesthetic qualities. The Commercial Yacht Code classifies yachts 79 ft (24 m) and over as large.
What does NMMA stand for?
The National Marine Manufacturers Association (NMMA) is the nation’s leading trade association representing boat, marine engine and accessory manufacturers. Collectively, NMMA members manufacture an estimated 80 percent of marine products used in North America.
What is the difference between an isolation transformer and a galvanic isolator?
An ISOLATING TRANSFORMER is completely different although the effective galvanic protection is the same. In this device there is never any continuous earth wire connection. Isolating transformers are big heavy and expensive, whereas galvanic isolators are small, light and cheap.
How do you test for galvanic isolation?
Put one lead on one side of the isolator and the other lead on the other side. As the capacitor starts to conduct current the reading should rise to approximately 0.9 volts. Remove the test leads, short the two wires of the isolator together to discharge the capacitor and repeat the test with the test leads reversed.
