Fire breaks out on 11mtr Motor Boat Dublin Bay ,

[SC35]

or it could be an insurance job?

I can think of many much safer ways to achieve that without the risk of serious burns.

Isn't that a rather foolish suggestion/allegation to make in relation to a boat that is probably easily identifiable

'High-current, sustained loads through a stainless washer can create enough resistance to start a fire'

at 12V what is considered a high current ?

I know not everyone are Nigel Calder fans but he makes a very good case over the issues of stainless steel in the conductive circuit.

Yes probably, foolish comment

Being dumb here but aren't my busbars stainless. And wago connectors?

If that's a dumb question, then I'm even dumber, because I didn't think to ask it.

according to google busbars are not solid SS

Every day's a school day - thanks for sharing

There could be any number of ignition sources causing this and having read the article there is nothing making any hypothesis more likely that another. Just as an aside, a cigarette is considered not to be a very competent ignition source within fire investigative circles generally, however accounted for most domestic fire deaths in Scotland when I was still working.

No, both are made from tinned copper.

Not suggesting putting stainless washer between terminals/lugs, but it would be very unlikely to get hot enough on most (all?) boats to cause a fire.

I recently did a Lithium installation on a boat where someone (a so-called "pro" i believe) had drilled holes in the side of the battery compartment and put stainless studs through the holes, each end of the studs had a washer and a stainless nut, all tightened up. The battery cables were connected to one side and all of the loads to the other side. Note, in particular, that the negative stud carries all of the current throughout the boat!!

But, nothing caught fire and the plywood isn't even scorched.

I'm not expecting that to be the cause of this fire but having seen too many boats go up from electrical faults, when I was doing my electrical apprenticeship, bad practice was always frowned upon (like stainless in the conductivity path) and on boats, I am even more thorough, even if it's mostly for my own peace of mind.
