do you want to elaborate a little bit I feel like so doing like you mentioned these surveys electrical surveys I've seen probably I would say that over 10 percent of the boats I walk on don't have that AC ground to DC ground tie they're expecting they've either removed it to prevent galvanic erosion which you say Obviously comes from it that AC to DC ground tie and what and the common one I get from these owners some of them do this deliberately and their pushback is well I get my AC ground from Shore so why would I do my ground tie to my DC and potentially live straight current corrosion so what's your response to that how would you what's your take on that common objection with doing a AC to DC ground tie on a recreational boat you'll go around any large Marina when you look at the short power pedestals and you'll see signs of burn marks you look at the show power chords you'll see signs of burn marks and that's because that's an unreliable Connection in in our houses the incoming power is bolted everything is bolted until we get to the the wall outlets and they're relatively low powered in our boats we obviously can't Bolt the short pedal connection so we've got this pin and sleeve connection which is inherently weak and then we're in a salt environment and maybe the cord when it's unplugged only drops it in the water and then fishes it back out again so then we get corrosion so we've got the potential for a poor connection there and the minute we get a poor connection on the grounding circuit we no longer have that safety ground and then anybody that touches equipment that's got a fault is likely to get a shock or the default current is going to find your way into the water but we simply cannot rely on that connection so then we provide the additional connection which is to the grounding circuit which goes to the water but then we've created the the shock hazard in the water so then we need the LC the electric leakage circuit interrupter to Mid against mitigate against that shock acid and many of those boats I'll guess that you're looking at which don't have that connection from the AC grounding circuit to the boat's grounding circuit or probably european-built boats because that's right the equivalent of an LC on their boats they call it a an rcd or residual current device and Dave relied on that rcd to provide the shock protection and therefore they felt that they didn't need the connection from the boats they see grounding circuit to the water however they changed the European standards in if I remember correctly in 2014 to to require that connection to the boat's grounding system and to the water but European boat Builders are still to this day will leave it off the boat which as long as the rcd is working fine is pretty safe but those rcds can fail closed to where they're not going to protect a boat and then at that point you really don't have a path for fault current to get it back to the shore well not a reliable path yeah it sounds like those galvanic isolators that used to fail open and you'd lose your AC Shore power grounding connection from a failure in the galvanic isolator when they used to now they fail now we we install the ones that fail closed but yeah that used to be a real a real challenge as well so if you're curious again go on our website and find out more answers and solutions with this sort of setup and thanks for asking and thanks for all of you for listening and tuning in
