I have just received the latest Tosh from Westhaven about increased "electrical safety" requirements.
The upshot is, that unless you have an electrical warrant of Fitness, you will not be able to leave your dehumidifier and battery charger running while you are away. This is whether you have your lead tagged or not. Ewofs are not the same as lead testing. They are designed for boats that have a full AC system fitted and are hard wired. They also cover your DC system.
As per usual, the Marina operators association mention no electrical standards and do not mention who is qualified to issue an eWof or what tests are involved. They also say that they themselves have no idea about electrickery, therefore putting themselves outside the loop of any discussion. That's handy!
The pretty brochure is attached.
I suggest the Marina Operator's association familiarises themselves with AS/NZS 3004 to see what they are lumbering their customers with and also to check whether any inspectors know what they are inspecting.. At a bare minimum I would expect any person inspecting the boat to have a copy of this documentation.
Everyone needs to be aware that to obtain a real Ewof, the boat's entire electrical systems, AC and DC require to be inspected, and all metal parts need to be bonded to the boat's earth with a resistance of less than 0.5 Ohms.
This is a real pain in the arse and if done correctly, will cost $$$$. I am also not sure that I want an MEN system on my boat, as it is not always the best idea. I will also have to do some reading about galvanic action created by connecting my boat's earth to the marina, and therefore every other boat in the marina. Any stray earth leakage currents created by these other vessels will end up sitting in my keel and rig and looking for a path to earth if for any reason the marina's earth is disrupted. I don't like that much.
Might be a good market for Galvanic isolators in the near future!
I will be interested to hear from Westhaven as to what calamitous events involving shore power have brought about this change in marina regulations..
