BSS fail - what happens next?

 This is one of 7 on Facebook Marketplace, several different models but I expect they are mains gas, but you have bottled gas jets

Not too worried about swapping jets around - assuming the correct ones can be purchased. May or may not have had to do the same the other way on a mains cooker in the past...

 

The issue is finding something which fits the hole. It can't be much bigger or smaller - smaller won't fill the cutout (only about a 5mm lip along the sides) and bigger can't go more than about 20mm. Not sure what the model you have found on Facebook is? I have already enquired in respect of the correct sized models in Spalding and Leighton Buzzard. There is another one in Swansea but I'm not sure how I would get to that one. Haven't spotted any others?

 

The Dometic HBG 3440 is particularly irritating. It is still listed on their website but nobody seems to have one in stock or I would just buy it.

Unfortunately not. If you look at the available items on their website they have a button where you can add it to your cart. That one you can only add to your wishlist, and if you click the tree link top left to other Dometic products you can see it isn't listed as an option.

 

We might have found one in Spain!

The last one is £290 with a sink. You could sell on the sink.

First one was a crazy price so I deleted it

Thank you for looking! Help much appreciated but unfortunately an error on my part. I should have typed 8003 or PI8003. It's the three burner one. Typo corrected in the original post.

Darn it, I'll keep looking. If it helps I've used Anyvan (www.anyvan.com) recently to pick up a sofa suite and they were fab and reasonable, so perhaps worth getting a quote for the hob on Facebook marketplace in Swansea?

 Thanks for the additional thoughts. Btw, this is what it now looks like following an evening of dismantling it.

Looks in pretty good nick. Hopefully any individual parts you need are easier to come by.

If you are stuck Alec I could do a run across to Swansea this weekend and at least get that one to Gloucestershire which is a bit closer!

It is my understanding that every wire coming from the positive terminal of the battery bank should have a fuse rated to protect the wire (except a heavy duty connection to crank an engine). This fuse should be as close as practical to the battery.

 

If there is a change to a lower rated wire at some point in the circuit, then a lower rated fuse may be needed.

 

Every device should have a fuse rated to protect that device (invariably specified by the manufacturer) either in a switch board / panel or in the wire. For lighting circuits & similar a load calculation and installation of a fuse slightly higher than normal load (but still low enough to protect the wire) would be used.

Thee are a list of exceptions to this 'rule', including such as : battery chargers, solar panels, bilge pumps etc etc.

They are all listed in the BSS guidelenes.

Are you sure they don't need fusing

I suspect Alan's confusing the fact that they can be permanently/directly connected to the battery (not via the main power breaker) -- which *is* in the BSS -- with whether they need to be protected by a fuse or not...

I thought that was not needing feeding via a master switch  - not fuses.

from a BSS point of view  - your understanding is wrong or the source your using is...  

 

if you look back up the thread there is clarification of the BSS requirements and what fusing is /is not needed

Er, I think I was rubbish at explaining what I meant - 3.6.1 requires isolators, 3.6.2 makes certain exceptions, allowing direct connection to the battery, where a suitable fuse or circuit breaker must be fitted. D'oh! 

 

3.5.3 requires that battery charging devices connected directly to the battery are fuse / circuit breaker protected. Excludes engine driven alternators.

 

Fortunately, my wiring up appears to be better than my writing as I've just had an installation inspected against this standard without any changes required - except that one piece of equipment was marked as non operational by the examiner. I wasn't there at the time, but when the purchaser queried this with me, I pointed out & then engaged the large, clearly marked circuit breaker on the obvious switchboard and, bingo, the equipment is now operational (this piece of equipment was defined by the manufacturer as requiring direct battery connection

 

I was also just wondering whether going "above & beyond" would be ok. I was thinking of a situation where family, hirers or friends borrowing the boat were rubbish at ever turning off the isolators - would fitting a suitably sized fuse to a supply even though going through an isolator, provide extra protection & be BSS acceptable - I can't see why not? I know some yachties do this.

LOL. Fair enough.   I can't see anyone picking you up for fitting extra fuses, assuming they were appropriately sized and installed properly. 

 

Personally I hardly ever use my isolators and tell family just to switch everything off at the distribution panel. But depends on your situation whether that would work for you.

I think that such a "master fuse" may well be mandatory under the RCR/RCR, so the BSS can't allow a fail if you fit one. It was the first thing I did on my boat when I got it, because many older boats are no protected in this way..
