Would RCD kick in.

[Bahco]

Been cutting slabs with an angle grinder and have been advised to keep the blade cool while cutting with perhaps a hose aimed at the blade in a trickle.

As water and electric do not mix, I am loath to do this for obvious reasons but am wondering if the RCD on the consumer unit would have been adequate protection in the event of water penetrating the grinder.

What do you think?

Not really no.

An RCD is to electrical installations the same as an air bag is to cars.

It is there as a back up so that if all else goes wrong hopefully you will not be killed.

It is not there to prevent you getting an electric shock, it will just hopefully limit the severity of the shock to a less than fatal level.

playing a little water over a slab is great for killing the dust, but the initial information of keeping the blade cool is wrong. if you feel the need to cool the blade, run it in the air to allow it to cool.

personally i've never had a blade get 'too hot' and i have used the cheapest diamond blade i could find on ebay, right up to the most expensive marcrist blades.

Obviously not advised by anyone who has actually done that.

If you did this, the resulting slurry of water and stone particles will splatter everywhere and make a hideous mess which will coat everything in the vicinity.

You also get wet hands, arms, legs, feet, infact everything.

If you really need blade cooling go and hire one that has this facility, as mentioned before you'll end up covered from head to toe in cack
