Re: Earth Leakage Protection/ Residual Current Device.

This is what happens when legislators with no technical expertise pass laws regarding technical things. Like not allowing 120v and 240v power in the same conduit, even though both phases of the 120v (which is where the 240v comes from) are .

You don't need to bond all your skin fittings unless you have a traditional wooden hull (carvel etc). Traditional wooden vessels with bronze underwater fittings require the fittings bonded to protect the timber from galvanic current - it destroys the cellar structure of the timber near the skin fitting if not bonded. In essence, the bonding allows the current to flow though the bonding wire instead of the timber.

Of course a fibreglass hull is essentially an insulator so with a fibreglass hull, you can elect to bond skin fitting and it seems that in North America, it is considered essential. In the UK and Aus, it is not done as much. I don't know what is normal practice in Europe or Asia.

However I'm sure you will get other views...
