CarpeDiem 430 Posted April 1, 2021 Share Posted April 1, 2021 What do people use for their boats external shore power inlet? I am struggling to find a 16amp panel mount inlet that is water proof when connected and not connected to shore power. Found this, it is the only IP56 I have found. Quite pricy. This is obviously IP nothing if it's unplugged. I understand that Ewof requires an external inlet. Our boat is very wet when racing, there isn’t a dry spot in the cockpit. If I could have the inlet inside then that would be best but I don't think that's allowed. Quote Link to post Share on other sites
Fogg 427 Posted April 1, 2021 Share Posted April 1, 2021 Often they are positioned inside cockpit lockers (with a cutout in the lid to allow the cable through). This is my setup typical on production boats I’ve had. 1 Quote Link to post Share on other sites
Jon 360 Posted April 1, 2021 Share Posted April 1, 2021 That’s similar to the fitting on my boat and it’s protected but outside Cockpit locker would be ideal on your boat CD if you have one as it’s officially not inside your boat. 1 Quote Link to post Share on other sites

In any case it comes with waterproof covers (according to the blurb). IP44 rating would be plenty - it is sufficient for sprays of water. If you are getting water at your marina jetty that is beyond a spray, you will be having bigger problems than whether your shore power inlet is sufficiently waterproof. Shore power has to be supplied through an RCD so there is little to no electrical risk even if water gets into the connector. Quote Link to post Share on other sites

I will investigate the cover, I didn't see that, thanks. Is IP44 sufficient for ewof? 14 minutes ago, aardvarkash10 said: Shore power has to be supplied through an RCD so there is little to no electrical risk even if water gets into the connector. We had an ebox once. The 10a outlet had a small amount water in it. Powered up fine, plugged in the battery charger and it smoked, smelled and went black. Neither the shore rcd or the ebox rcd tripped, it wasn't a happy box. So my approach is to keep the water out of the 230v electrical system whether it's on or not.

aardvarkash10 958 Posted April 1, 2021 Share Posted April 1, 2021 I'd ask one of the people listed in this document. https://www.westhaven.co.nz/getmedia/e07684df-252d-4b62-8cc2-a2146400a62a/Electrical-Connections_2.pdf/ Quote Link to post Share on other sites

SCAME fittings are the "default" option in NZ https://www.firstflex.co.nz/product-category/scame-plugs-connectors/ these are designed to be in the weather, both for IP rating and plastic type, but better if you can locate it in a locker if possible. You should buy an IP67 rated inlet. 1 Quote Link to post Share on other sites
Fogg 427 Posted April 1, 2021 Share Posted April 1, 2021 Suggestion. Before taking any action I’d suggest you ask the person you plan to do your eWOF compliance check. Because being the NZ marine services industry it’s full of ambiguity, vagueness and bad advice. Every time I’ve asked a different inspector for an eWOF checkup I’ve got a different set of answers. So I’ve learned to keep asking until I get the answer I like the best and go with that. Seriously. Quote Link to post Share on other sites

Black Panther 1,584 Posted April 1, 2021 Share Posted April 1, 2021 I've been priced out of marinas. So now I get to save even more by ignoring this clusterfck. 1 Quote Link to post Share on other sites

That is not the sole reason. It is to ensure a high level if electrical safety in all area's. Remember back in the day, not that many years ago, where there were always complaints of the boat next door causing stray earth issues? When was the last time you heard of that? Remember that our boats are in a place of high electrical shock potential. So having proper elctical wiring practice being adhered to is essential. Quote Link to post Share on other sites

Remember that our boats are in a place of high electrical shock potential. So having proper elctical wiring practice being adhered to is essential. The last time I heard of a stray current in a marina full of allegedly inspected abs eWOF’d boats was last month on my marina around my boat - I did an unscheduled liftout of Fogg and found that my 2 new anodes fitted 2 months earlier were 75% gone. I had an electrician check over Fogg abs found nil leakage of my systems therefore only source was another boat near me. Upon enquiring around my berth neighbours they all agreed they had noticed their own anodes corroding mysteriously quickly. So I had a galvanic isolator fitted to protect Fogg regardless of what’s happening around me. Quote Link to post Share on other sites

That’s to enable a single 32A supply to split across two 16A inlets - one does all house systems the other is dedicated to HVAC systems (of which there are two). If I try to run all my systems together I exceed 16A hence the split inputs. As another option, if I can’t get a single 32A socket then I also have 2x separate shore power cables so if necessary I can plug into 2x 16A sockets and run both cables to Fogg side by side.

Plus, if a fault were to ever develop, the inline sockets are 16A unprotected into a 32A supply. Not exactly legal. Not saying you shouldn't. I have been kown fot the odd "creative" wiring ideas when in need. But just be aware. Yes two cables are best, or a single 32A and then split inside the panel with it's own 32a Breaker on supply and appropriat breakers to everything else Quote Link to post Share on other sites
