Wd40 and fuse boards.... Anybody tried it?

[Gavin John Hyde]

Had the WD40 out earlier cleaning my fiancees bike up.
Saw on the side they suggest it can be sprayed into mcbs on a fuse board.
Can't say I have ever thought of that. I know it can be used on contacts but it somehow seems wrong to be spraying a liquid into a fuse board as shown on the can!

I use it to clean Terracotta tiles, but would be a bit wary of spraying it inside a CU.

 

[telectrix]

i'd not use it on MCBs. if necessary, switch cleaner is the better option.

Hmmm...it says it removes moisture from them, but if mine were wet I'd probably replace them.
Mind you, last year I bought a can of compressed air for cleaning dust from delicate machinery...think it was nearly a tenner...for air! It did work though...

 

[Lucien Nunes]

Great... spray volatile flammable liquid into a source of ignition. I think that's a balls-up by their publicity department and they should probably replace that pic with something that is not directly prohibited by their own instructions. I suppose they meant to show a wet distributor cap or something.

A couple of newish cans I can see here do not have that pic though.

Not so sure about wd40 on paintwork either
my mate has a spray shop for vans etc won't have wd anywhere near it

Down here they spray it on toilet seats to stop recreational drug use...

Haha, I remember having to treat the bogs to that solution when I worked in a pub.

The flash point of WD40 is similar to that of diesel so as a liquid it does not evaporate at room temperature to enable combustion from a heat source. Obviously if sprayed direct from the can it is a vapour and mixed with oxygen you have the two of the three elements to start a fire. Sprayed into a protective device will only cause an issue if you introduce the element of heat which could happen if you were switching it on and off prior to spraying it to create a spark.

Funny cos I don’t recall seeing that usage in pictures on the can ha ha ha

What’s the idea of that? Stops the druggies from squeeking???

back to the tin of wd40.
Look at that CU.... no blanks in the spare ways

Good contact with the seat after splash backs...

Heard of people doing it but the fear of spraying liquid in a board is too much for me.

I have seen loads of HV circuit breakers that were completely gummed up because some nugget had sprayed them with WD40. The trip mechanism on a circuit breaker is quite delicate but WD40 leaves a waxy film which jams the mechanism and stops the circuit breaker from tripping.

WD40 is flammable as it is oil based.
