Stanton Truma heater access

That's an interesting thought Dennis.

As Quilter has recently discovered, losing the mains electric function of the Truma boiler is a real pain (specially when abroad, as she is at present) as it's so difficult to replace the fuse on some of our vans.

I'm wondering if it's worth doing as you suggest - if only to isolate the variable voltage factor from the equation?? 

Gromit, for <£20 why not?

Actually occurred here in the UK.  I have the AVS30 set to activate "immediately" on sensing low voltage - it can be set to wait a predetermined time in case the issue is a short transient. I also have it set quite high - from memory around the 170-180V level.

I have set the wait time when plugging into EHU to about 20s.

Has it earned it keep - well I don't know. But the original purchase seemed to make sense trying to protect an expensive Schaudt system (by comparison the additional Schaudt module cost close to £95+ and only did overvoltage protection).

I don't know how good the Sargent system is at protecting against spikes etc.  I assume there might be some capability built-in??

Impeccable logic Dennis. 

Pity the waterproof box costs £95!!! 

(I jest, of course.)

Of course, I could save on the connectors and wire it at one end of my EHU cable and make a "Protection Cable"

Dave,

4way version of this enclosure £10.95 (I know you were joking)

That's why I was hesitating Dennis. (Thanks for the link).

I've yet to find a suitable looking box that isn't a great big lump. I don't really want a small bungalow dangling from the side of the van, and if I put it on a longer lead I would probably need planning permission! 

I wonder if there's a dedicated in-line voltage protector that's a bit smaller and more streamlined?? Mr Google seems to know nothing, for once!

Thank you Peter. That looks much better and as you say it wouldn't be a problem tucked under the van, not would it be too bulky in storage.

Food for serious thought. I've no idea if voltage fluctuations are the cause of the fuse blowing, but with one of these in line it would eliminate that possibility. Not much cash involved, so I may give it a try!!

So am I Peter, as you will have gathered.

I can only think it's an inherent problem with the boiler, as the failures seem to have no detectable pattern - not that Messrs Truma are likely to own up to it! I may give the voltage protector a try, but probably won't bother since like you, I'm not convinced it will cure the problem.
