Last time I checked, the Recreational Craft Directive and EMC Directive do not help much re this question. There is the EN 60945 standard which includes sections on EMC for marine navigation and radio systems, and I've seen some non-navigation equipment approved to that standard, but it sounds like your equipment is out of scope of that standard. That means you're left with the "normal" non-marine EMC regime.

I'm told US, Canada, Australia and then EU are the markets. -Doug From: [email protected] [mailto:[email protected]] On Behalf Of [email protected] Sent: Thursday, January 08, 2009 10:16 AM To: Doug Kramer Cc: [email protected] Subject: Re: Sanity check on AC motors for boat use Depends upon what is meant by a "Boat" A Recreational Vessel or a Commercial Vessel? I would think the later needs to conform to requirements of the International Association of Class Societies E10 standard. Or more particularly perhaps to the standards of the actual Class Society (Lloyds Register, American Bureau of Shipping, etc.) who is approving the design and construction of the vessel. YMMV John Merrill Square D Automation "Doug Kramer" <dkramer@nceelabs To: <[email protected]> .com> cc: Sent by: Subject: Sanity check on AC motors for boat use [email protected] 01/08/2009 10:48 AM In reviewing standards as applicable to DC powered (battery) motors for use on boats, as I’m seeing it that applicable EMC directive standards to apply would be EN55012 and EN55014-2. EN55014-1 excludes devices used exclusively in vehicles. Another route to go would be in looking at EN61000-6 series for immunity. I think the emissions requirement is very straight forward. A long I/O or control line in addition to the DC power cables causes a pause for thought, but is easily tested and addressed in EN55014-2. Thoughts?
