Mystery Object on boat.

[lustyd]

It's earth cable, it doesn't matter.

Only Earth wiring, so no danger of shock

Depends what it’s connected to. It’s not the green that makes it safe!

What ?

 

[lustyd]

What ?

It’s green and yellow so is wire generally used for earth. It can easily be connected to live though, and we can’t see in the picture that it’s not so declaring it safe is unwise. I know you know this, but since two people declared it safe I thought it worth a mention. It’s probably safe but further checks required.

For clarification, had I engaged Mk1 eyeball before keyboard finger Mk1 , would have possibly noticed that the wiring was connected to bolts postioned immediately above the location of hull anodes.

There are two Earth wires connected to a galvanic isolator, don't think there's too much chance of it all being connected to live, or the shore power wouldn't work.

What about the 5Kg weed, & 3 illegal immigrants, that you have not mentioned

Any "Weed" on the boat is available in large quantities at a very reasonable rate, discounts for bulk purchase.
We sell on a Scrape-your Own basis and only use the the finest and most expensive growth encouragers available in our local chandlery in wide choice of very pointless and ineffective colours
Rest assured that everything is sustainably sourced and produced very locally indeed under our "Direct from Hull to Customer" Greenwashing programme.
Guided tours available, bring your own waterproof gear.
We will be shortly be opening up a Franchising Deal..........................
We should warn under the T & C s that you may need a small Flame Thrower for best effect with this stuff.

Oh I must have missed the bit where he said it did work.

If it had been wired to live, shore power would never have worked from day one.

Paul, Didn't your Mother ever tell you not to argue with those who know best

That depends whether the other side is in fact wired to ground. It’s entirely possible both sides go to live. Prudent people check first regardless of expectations

Get a grip.

Sorry but experience has taught me to be cautious around other people’s amateur wiring. I’d have thought that came up in your training too.

It's a galvanic isolator, with two Earth wires, fitted by a professional. Why would any sane person think that both Earth wires go to live ?

If you apply your logic to all the other posts on here it would be impossible to answer anything without an endless list of the different ways someone might have done things incorrectly in the past.

I stand by my original post, nuff said.

I’ve seen stupider things on boats and in houses. I also stand by my post, we can’t declare those wires as safe just because they’re green and appear to be on a GI unit which we aren’t certain is one.

You really are something else. Everyone else reading the thread can see it's a GI. You simply made a post that made no sense and cannot stand to be wrong, as is often your want.

Out.

Just looks like a generic heat sink with some chaps name on it to me. Could be literally anything. I’m not stopping you testing it with your tongue if you want to, just pointing out that green doesn’t mean safe earth wire, it’s just wire and can be used for many purposes. Sensible folk confirm before declaring something definitely safe and not in need of insulation.

Since the guy (Paul Allen) is still in business but now repairing 3KvA and larger gennies, I would credit him with some expertise in electrical engineering.

NP Generators Leics

(Using same contact details as on the sticker on the galvanic isolator so easily contactable to verify)

This is why i'm the marine electrician and you're just some random bloke on an internet forum.

I didn’t say anything against him. Just highlighting that without further investigation it’s unwise to assume a green wire is safe. Very surprised a professional disagrees with that stance, but maybe he’s more cavalier than I gave him credit for.
